轮机英语阅读理解108题
第四章关联题108题Passage 1Valve drive mechanismThe valve drive mechanism commands the inlet and exhaust valves at the required timing.The valve drive mechanism consists of an inlet and exhaust cam follower (8) each suspended in a plunger of the tappet assembly (7), two tubular push rods (4) with ball joints, two nodular cast iron rocker arms (2) suspended in a rocker arm bearing bracket, two yokes (5) and a yoke guide pins. See Fig. 4-1.The tappet rollers follow the cam profiles and transfer the movements through push rods to the rocker arms. The rocker arms operate the inlet and exhaust valves through yokes (5).Lubrication for the rocker arms comes from the engine' s secondary oil supply manifold through drillings in the cylinder head and rocker arm bracket.The tappet assembly receives lubricating oil via channels in the engine block from the main supply manifold. For the roller and shaft, the oil is supplied through the guiding plunger.To compensate for heat expansion a clearance must exist between the rocker arm and yoke. All adjustments have to be done on a cold engine only.Fig-4-1 Valve drive mechanism1. According to the passage, the best time to adjust the valve clearance is_____.A. before the engine is startedB. when the engine is runningC. after the engine has just been stoppedD. when something has gone wrong with the engine2. The roller and the tappet assembly are lubricated by means of ________.A. the main lube systemB. the secondary oil systemC. the special pumping systemD. the turbine oil system3. According to the passage, the valve drive mechanism does not include ________ *A. tappet rollersB. push rodsC. nodular cast ironD. yokes and guide pins4. To close valves tightly, which clearance should be inspected according to the maintenanceschedule?A. The one between the cam and the tappet roller.B. Tlie one between the push rods and the ball joints.C. The one between the rocker aims and the yokeD. The one between two tubular push rods.5. Which statement about the passage is not true?A. All adjustments have to be made on a hot engine^ only.B. For the roller and shaft, the oil is supplied through the guiding plunger.C. The valve drive mechanism commands the inlet and exhaust valves at the required timing.D. The rocker arms operate the inlet and exhaust valves through yokes.Passage 3Charge air coolerThe engine is equipped with a charge air cooler. The insert type charge air cooler is mounted in a welded casing (air trunk) . Tlie trunk is bolted to the engine block.Standard is a two-stage cooler mounted. The first stage, through which the charge air flows, is cooled with water from the HT cooling system and cools the charge air till approx. 90 - \00癈. Tie second stage is supplied with water coming from the LT water system and cools the charge air mrther till the required temperature of approx. 50 X.. By controlling the water flow through the LT cooler the charge air temperature can be kept constant at the required temperature.The circulating coolant water should always be under positive pressure and should be as clean as possible. The operating air temperature should be maintained by controlling the coolant inlet temperature.Whilst the engine is running the air and coolant temperatures and pressures at inlet and outlet should be checked and logged periodically. Variations from normal indicate faults developing such as fouling of the film plates or obstruction of the water tubes.Check daily, during operation of the engine, the working of the telltale hole at the free end of the charge air receiver. The function of this hole is to inform the operator the presence of water in the charge air receiver. Under normal condition only compressed air should escape from this hole.1. According to the passage, the expression " HT" probably means ________.A. HIGH TANKB. HIGH TEMPERATUREC. HEAT TRANSMISSIOND. HEAT TRANSFER2. In order to maintain the charge air temperature we should control ________.A. the coolant inlet temperature coming from the first stage coolerB. the coolant flow coming from the second stage coolerC. the coolant outlet temperature coming from the second stage coolerD. the coolant flow coming from the first stage cooler3. The charge air temperature departing from normal may indicate that _____A. condensate can be formedB. only compressed air should escape from the telltaleC. the film plates are becoming dirty or the water tubes are blocked by scaleD. cooling water may have been carried into the cylinders4. The function of the telltale hole is to ________.A. detect whether compressed air has escaped from the holeB. control the coolant inlet temperatureC. determine whether the coolant water is under positive pressureD. inform the operator the presence of water in the charge air receiver5. Which of the following statements is not true?A. The engine is equipped with a charge air cooler.B. A two-stage cooler mounted is standard.C. The first stage is cooled with water from the LH water system.D. The second stage cools the charge air further till about 50ºC.Passage 19Starting air systemThe engine is started with compressed air of max 30 bar. Minimum pressure required is 15 bar. A pressure transmitter PT301 mounted on the starting air line before the main starting valve has an indicator in the instrument panel. The supply line from the starting air bottles is provided with a non return valve and a drain valve.The solenoid valve is electrical (remote control) or manual ( on the engine) operated and send after activation a pilot air signal to the main starting air valve. Interruption of the control air doses the main starting air valve.After the main starting air valve is activated the air flows through the flame arrestere to the starting air valves in the cylinder heads. Part of the air Hows via the starting air distributor to each of the starting air valves in the cylinder heads. The starting air distributor controls the timing of opening and closing of the starting air valves. On the moment the main starting air valve is operated also the governor booster is energized. The main starting air line is provided of a safety valve. Interlock valve is a safety device to avoid an engine start with engagedtuming gear.1. As the engine is started with compressed air, the correct sequence of the following devices beingactivated is ________.①solenoid valve; ②starting air valve; ③starting air distributor; ④main starting air valve ;⑤governor booster.A. ①,⑤,④,②,③B. ①,④,⑤,③,②C. ①,④,③,②,⑤D. ④,③,①,②,⑤2. The sentence " the governor booster is energized" ( paragraphs) probably means ________.A. the governor booster is supplied with electric powerB. hydraulic oil is pumped into the governor boosterC. the governor starts to work before starting the engineD. the governor booster is supplied with pressurized air before starting the engine3. Which of the following components are attached to the air bottles?A. a pressure transmitter FT 301B. a non-return valve and a drain valveC. a solenoid valveD. a starting air distributor4. When the engine is engaged with turning gear,________ can keep the engine from startingA. the control airB. the solenoid valveC. the main starting air valveD. the interlock valve5. The phrase"flame arresters" (paragraph 3 ) probably means________.A. air filtersB. fire extinguishersC. stop fire netD. hydrant connections Passage 20Starting air distributorThe starting air distributor is of the piston type with precision machined inter changeable liners.The liners as well as the pilot pistons are of corrosion resistant materials. The pilot pistons are controlled by a cam connected to the camshaft end. When the main starting valve opens, the pilot pistons are pressed onto the cam, whereby the pilot piston for the engine cylinder which is in starting position admits control air to the main piston of the starting valve . The starting air valve opens and admits compressed air into the engine cylinder forcing that piston down. Shortly before the exhaust valves are opened the pilot valve interrupts the control air to the starting air valve and starting air to that cylinder is stopped. This procedure will be repeated as long as the main starting valve is activated or until the engine speed is so high that the engine fires. After the main starting air valve is closed, the main starting air system is deaerated, the pressure drops quickly and the springe will lift the pilot plungers off the cam. Tins means that the pilot plungers touch the cam only during the starting process and thus wear is insignificant.If a pilot liner is worn out, press it out. It may be necessary to heat the distributor up till about 200ºC as Ixtgtjtg is used for fixing and sealing.1. According to the passage, the liners of the starting air distributor ________.A. can be replaced when worn outB. are made of heat resistant materialsC. are welded preciselyD. are worn out easily during the starting process2. During the starting process, when ________, the main starting air valve is closed.A. the exhaust valves in the starting cylinder are openedB. the pilot air to the starting air valve is stoppedC. the engine speed reaches fire speedD. the pilot pistons are pressed onto the cam3. When some cylinder of the engine admits compressed air into it, the pilot piston of the starting airdistributor should be _________.A. separated from the camB. pressed onto the camC. lifted off the camD. pressed onto the cam repeatedly4. From the passage we know that "Loctile" is probably________.A. a type of gasketB. a kind of lubricantC. a glue bondD. an anti-corrosion additive5. Which of the following statements are not true?A. The pilot air controls the opening or closing of the starting air valve.B. The starting procedure will be repeated until the engine speed is so high that the engine fires.C. After the engine is started, the main starting air system is drained.D. When the engine stops, the pilot plungers of the starting air distributor are separated from thecam.Passage 27The engine' s supporting element consists of a bedplate and frame. The bedplate can be of welded or cast design. The frame is made of cast iron. The turbocharger mounting, the housing for the air cooler andthe charging air receiver are cast as an integral part of the frame. The underslung crankshaft' s main bearings are mounted in bores in the frame and secured with main bearing caps of steel. The caps are guided sideways and are secured by means of threaded studs and nuts that are tightened hydraulically.The caps are also secured with horizontal bracing screws in the frame.The bearing shells are produced with a tolerance that makes it possible to change them a set at a time without any scraping-in.The top flanges of the cylinder liners are forced against the top face of the frame by the cylinder covers , whereas at the bottom they are guided by a bottom flange through which they are free to expand under the effects of heat. Tightness between the water chamber and the crankcase is achieved with two rubber rings inserted in slots in the guide surface of the cylinder liner.The camshaft is driven from the crankshaft through a gearing, which is mounted on the engine's flywheel end and covered by a 2-part shield. The camshaft runs in steel bushes lined with white metal.In each side of the frame, large openings are provided for inspection of roller guides, cams and the main and crank bearings. The openings have covers, some of which are provided with crankcase explosion relief valves that equalize the pressure if the oil vapors in the crankcase are ignited, for example as a result of hot running.The bedplate can be used as a lubricating oil reservoir and is therefore provided with a dipstick. The oil can, however, be drained off to a special bottom tank, so that the engine runs with a dry sump.A fuel oil pump of the gear type is driven from the camshaft through a clutch. A lubricating oil pump, which is of the same type, is driven by a clutch mounted on the end of the crankshaft or, for propulsion plant, through a flexible gear wheel drive.(The following questions are based on the passage above)1. This passage is mainly about ________.A. the construction of an engineB. how the engine worksC. the lube and cooling system of an engineD. when the crankcase explosion occurs2. Which of the following is NOT mentioned as an integral part of the frame?A. Turbocharger mountingB. Bearing capsC. Air cooler housingD. Scavenging air reservoir3. The camshaft ________.A. is supported by bearingsB. may not drive the fuel oil pump in some casesC. will not drive a lube oil pumpD. All of the above are true.4. Which of the following is NOT true?A. The frame is made of cast iron.B. There are underslung bearings in this engine.C. Four rubber rings ensure the tightness between the crankcase and the water chamber.D. Relief valves are provided on the frame.5. Which of the following word can be used in stead of the word "equalize" (underlined in the fifthparagraph)?A. EquivalentB. InterferenceC. ReleaseD. FixPassage 28The cylinder cover is made of cast iron and is provided with two inlet valves, two exhaust valves, a central mounted fuel injection valve and an indicator valve. The inlet valves are mounted with separateseating rings made of special heat-resistant cast iron. These rings are pressed into the cylinder cover in cooled conditions. The exhaust valve searings are special, water-cooled seating rings. These rings are also pressed into the cylinder cover in cooled conditions.Each cylinder cover is provided with cooling water from a screwed-on tubular cooling water jacket through radial bores in the thick bottom of the cover. Each of the radial bores is connected to two side bores. The cover has forther separate bores that lead to the cooling water jacket and the bores in the cylinder cover to a common outlet chamber. The cylinder cover and cylinder liner are assembled by means of four threaded studs screwed into the frame. Tightening is effected by means of hydraulic tools, and sealing by means of a thin ring mounted between the cylinder cover and the cylinder liner. A starting valve is mounted on the side of the cylinder cover.The engine has oil-cooled pistons of cast iron. The pistons are provided with three compression rings and a spring-loaded scraper ring. A space for cooling oil is provided at the top of the piston. The scraper ring prevents lubricating oil from being drawn up into the combustion chamber.Oil for cooling the piston crown is led from a bore in the crankshaft through a channel in the connecting rod and the connecting rod journal, to die bushing for the gudgeon pin. This bushing is provided with an annular groove from which part of the oil is led for lubricating the gudgeon pin. Tile remaining oil continues through bores in the gudgeon pin and the piston to piston cooling chamber.(The following questions are based on the passage above)1. This passage is mainly about ________.A. cylinders and cylinder coversB. cylinders and pistonsC. cylinder covers and pistonsD. cylinders and oil2. Which of the following may be provided on top of the cylinder cover';'A. Two exhaust valvesB. A starting valveC. An indicatorD. All of the above3. Which of the following is true?A.

The scraper ring scrapes the oil downwards.D. The piston cooling is of splash type -5. The "four threaded studs" (underlined in the second paragraph) means________.A. studs which have four threadsB. four threads studsC. four studs that have threadD. threads for studsPassage 29Each of the engine cylinders is provided with a Bosch, type FF, fuel pump. The fuel pump is a single-acting plunger pump with non-adjustable stroke. The plunger is so accurately ground and lapped that its clearance inside the barrel is only 0.002 ~ 0.003 nun. This provides sufficient tightness between plunger and barrel, even at pressures as high as 200 - 400 bar, without the need for sealing materials.Neither the plunger nor the barrel can therefore be renewed individually. The plunger pressure stroke is produced by a cam on the engine camshaft, whereas the return stroke, the suction stroke is effected by means of a strongcoil spring. The top of the pump barrel is closed by a spring-loaded pressure valve, to which the fuel oil pipe for the respective fuel valve on the relevant engine cylinder is connected.Regulation of the amount of fuel delivered by the fuel pump is achieved by turning the pump plunger, the cylindrical surface of which has a milled recess. The bottom of this recess ends with an edge, which is at right angles to the cylinder generating lines, whereas the top of the recess is limited by a helix. This produces an inclined control edge on the plunger, which also has a narrow longitudinal groove. In the pump barrel are drilled two diametrical holes through which the ftiel oil can flow into the fuel pump barrel. The pump barrel is surrounded by a regulating sleeve, the upper end of which is shaped as a toothed rim. The lower end has two lengthwise slots in which projecting lugs on the lower end of the plunger can slide up and down. The end of the regulating rod from the engine governor is designed as a toothed rack that engages with the toothed rim on the end of the regulating sleeve. This makes it possible to nun the pump plunger during engine operation.(The following questions are based on the passage above)1. The fuel pump ________.A. is ofFF typ.B. is of reciprocating typeC. has an inlet valve and an outlet valveD. A and B are true.2.

The word "inclined" (underlined in the third paragraph) means ________.A. sloppedB. slopingC. slungD. slottedPassage 30Governing prime movers, particularly diesel engines, require careful consideration. The cyclic variations of a diesel cycle can be passed into the governor drive if it is too "stiff". Tnat is, the cyclic vibrations will be imposed on the internal gearing etc. inside the governor housing. To prevent this, some form of damper should be used on the drive into the governor. The mounting point for the governor should be rigid; a vibration mounting would soon downgrade even the best of governors. Chain or belt drives should be avoided as far as possible, as slapping of the belt or chain produces speed variations causing malfunction of the governor. Similarly the drive from the end of the camshaft is subject to torsional vibrations, and governors should not be located at that point. They should be located as close as practicable to the fuel pumps, thereby limiting the mass/inertia of operating linkage. hi all cases, the governor should be matched to the engine requirements in terms of droop, load limiting, response time etc. On large engines there is an inertial resistance to acceleration within the masses of reciprocating and rotating elements of the engine, so that during acceleration fuel could be released to the cylinders at a faster rate than efficient combustion can bum it. In an attempt to compensate for this, and to maintain acceptable combustion during acceleration, a tapping from the scavenge space may be taken and the pressure used to regulate the rate offuel released to the engine. This process is incorporated into the governor operating system so that the governor releases a quantity of fuel commensurate with the increase in air pressure in the scavenge space. ( during deceleration the problem is not so great, as excess air can be tolerated far more easily than can the incomplete combustion associated with insufficient air.)(The following questions are based on the passage above)1. This passage is mainly about ________.A. mounting the governorsB. the scavenge pressure limit to the governorC. A and BD. how the governor regulates the fuel index2. The drive to the governor ________.A. should be rigidB. should use damperC. should use chains or beltsD. should be from the end of the cam shaft3. The governor should be mounted close to the fuel pumps ________.A. for limiting the inertia effectB. for limiting the loadC. to ensure speed droopD. to cut down the cost4. It can be inferred that with scavenge pressure limit ________.A. the engine can be accelerated rapidlyB. the engine can be decelerated rapidlyC. the governor will supply fuel oil efficientlyD. the combustion will be more complete5. The word "downgrade" (underlined in this passage) may mean_____.__.A. a lower gradeB. reduce to a lower gradeC. the extent to a lower gradeD. raise the gradePassage 31After the shut-on" valve of the starting air receiver has been opened, the air flows at full pressure through the filter to the main start valve "A" (with complicated construstion), thereby applying pressure to pipe between the main start valve "A" and the starting air control valve. Providing that maneuvering hand wheel is in the "Stop" position, all other pipes are without pressure.If the wheel is turned towards the "Start" position, a pawl above the starting air control valve is actuated and the valve is opened, allowing air to flow to the main start valve "A" . It opens to allow a direct through-flow of air. All cylinder starting valves are thus exposed to air pressure and, furthermore, air flows to the starting air distributor, which is controlled by the camshaft. The distributor has a series of slide valves arranged radially around the camshaft-one slide valve for each cylinder. These supply pilot air to the cylinder starting valves with pistons in the "Start" position. The rotation of the engine crankshaft commences, after which the cylinder starting valves are opened in the correct sequence - The crankshaft is thus brought to speed of rotation necessary for compression and ignition.When the maneuvering hand wheel is turned, the governor is actuated through a flexible cable setting the fuel pumps. However, a fuel index limiting arrangement is inserted, which keeps the regulating shaft and thus the fuel pumps at zero index during the starting process, ensuring that fuel is not injected into a cylinder during the supply of starting air.When the engine crankshaft has reached the necessary speed, the hand wheel is turned further past the "Start" position with the result that the arm above the starting air control valve is released and the valve is closed and vented. At the same time, the control piston in the main start valve "A" is also vented , thus blocking the supply of air to the cylinder starting vales, the starting air distributor and the fuel index limiter. Gradually, as the handle is turned further towards the maximum position. The governor increases the fuelpump index and the crankshaft rotates more quickly. The governor ensures that the maximum permissible speed is not exceeded.(The following questions are based on the passage above)1. This passage is about ________.A. starting air system and speed regulating systemB. start of the engineC. governorD. crankshaft2. If the shut-off valve of the starting air receiver is opened ________.A. the cylinder starting valves are subject to pressureB. the air flows to the starting air distributorC. the starting air control valve is actuatedD. None of the above is true.3. tf the hand wheel is positioned "start"________.A. the starting air control valve will be openedB. individual starting valve on each cylinder will be exposed to pressureC. there will be cylinder starting valve or valves openedD. All of the above are true.4. During the supply of starting air to the cylinder ________.A. air is consumedB. fuel oil may be supplied to the cylinder or cylinderd for reliable startingC. the control piston in the main start valve "A" is ventedD. All of the above are true.5. The word "blocking" (underlined in the fourth paragraph) most probably means_____.A. interposingB. covertingC. stoppingD. distributingPassage 32The governor drive is placed on the stem end of the engine and consists of a cylindrical gear wheel which is driven by the gear wheel on the camshaft, plus a set of conical gears. The function of the governor is to control the effective stroke of the fuel pumps, so that the rev/min of the crankshaft is maintained constant within certain limits, independent of the load.The action of the governor is transferred through arms and draw rods to a longitudinal regulating shaft on which a 2-part arm is provided for each fuel pump. The 2-part arm comprises an aim holder and a spring lever which are connected by a spring, thereby enabling the governor to control the pumps even if one of the pump pistons seizes. TTie movement is transferred from the spring lever to the toothed rack of the pump through a linkage.The regulating shaft is also provided with a stop arm which can be moved by the piston rod in a stop cylinder that is activated when the engine' s overspeed trip comes into operation. The piston rod in the stop cylinder influences the stop arm, whereby the regulating shaft is turned and the fuel pumps are set in the "Stop" position, thus stopping the engine. The Woodward governor tries to maintain the regulating shaft in the "Running" position, but between the governor and the regulating shaft there is a flexible draw rod that can be compressed and thus allows the regulating shaft to be moved into the " Stop" position.If a cylinder is to be set out of action, e.g. when measuring the compression pressure, the spring lever and thereby the toothed rack of the relevant fuel pump is moved to the zero position.(The following questions are based on the passage above)1. This passage is mainly about ________.A. working of the governorB. the camshaftC. fuel index regulating of the engineD. the fael pump2. The governor ________.A. is driven directly by the crankshaftB. is driven with chains by the camshaftC. is in the middle partD. None of the above is true.3. If a fuel pump piston seizes ________A. the stop cylinder will be activatedB. the governor will be damagedC. the relevant spring will be compressedD. the flexible joint will be compressed4. When measuring die compression pressure in the cylinder ________.A. the engine should be stoppedB. the fuel pump should be stoppedC. the toothed rack of the relevant fael pump should be moved to zero positionD. None of the above is true.5. Which of the following can be used instead of " independent of" (underlined in the first paragraph)________.A. Dependent onB. ExtendingC. On account ofD. Regardless of Passage 33Where routine maintenance is concerned, the governor should be checked regularly for adequate lubrication. The operating range is usually quite small, giving a tendency for them to wear over limited areas . Then a sudden and larger change in speed than normal may carry the governor onto a ridge of debris or gummy oil deposit so that it may stick at that point. To restrict this problem as far as possible, the governor pivots, slide, etc. should be cleaned and well lubricated whenever possible. It should be born in mind that the governor structure is such that, were the spring to fracture in any way, the flyweights would be able to move outwards and shut the engine down. The connections from the governor to the fuel racks should be designed in such a way that the governor can both increase and decrease the fuel within the bounds of some hand setting; i.e. the governor can adjust the fuel settings but cannot release more fuel to the engine than is dictated by some predetermined value set by the engine operator.To overcome the above limitations of the CF governor, "servo governors" have been developed. These use the power of hydraulics to pump the heavier fuel rack systems associated with larger engines in to the desired position. This "powered" operation is rapidly and accurately achieved, and the hydraulic flow can be either electrically or mechanically controlled. The speed sensing can be done by a tachometer arrangement that can be set to the desired speed, and on sensing any variation a solenoid operated flow valve allows pressurized hydraulic flow into a servo system of pistons/plungeis which resets the rack positions. Although this system is quite effective, more mechanically controlled governors are fitted to larger engines. These use the principle of the CF governor, i.e. fly weights acting against spring pressure, but instead of the slide working directly onto the fuel racks it simply regulates the flow of hydraulic fluid to servo pistons controlling the rack positions. this system therefore has the proven reliability and sensitivity of the small CF governor and yet develops quite a large governor effort through the hydraulic fluid.(The following questions are based on the passage above)1. Which of the following is the reason that the governor discussed sticks?A. The governor is not sensitive normally.B. It is because of wear in normal working range.。

A monitor is required to measure these values and provide both continuous records and an alarm where the permitted level is exceeded. The principle used is that of ultra-violet fluorescence. This is the emission of light by a molecule that has absorbed light. During the short interval between absorption and emission, energy is lost and light of a longer wavelength is emitted. Oil fluoresces more readily than water and this provides the means for its detection. A sample is drawn off from the overboard discharge and passes through a sample cell. An ultra-violet light is directed at the sample and the fluorescence is monitored by a photoelectric cell. Where an excessive level of contamination is detected an alarm is sounded and diverting valves are operated. The discharging liquid is then passed a to slop tank.(1)A monitor can obtain all of the following functions except___CA measuring oil content valuesB providing continuous recordsC lowering the oil content below 15ppmD providing an alarm unit warning of levels of discharge in excess of 15ppm(2)A sample is drawn off from __D and passes through a sample cellA bilge waterB discharge of oil separatorCslop tankD discharge of oily water separator(3)the passage is mainly about ___DA oil pollutionB current regulations related to oil pollutionC oil in water monitorD the principle of ultra-violet fluorescence(4)from the passage, we can learn that the ultra –violet fluorescenceIs a kind of _____DA oil sampleB lightC photoelectricD alarm unit19.in an auxiliary diesel engine bypass type lubricating oil system, the main lube oil pump forces ___BA all of the oil used by the engine through a filterB some of the oil used by the engine through a filterC some of the oil used by the engine through a centrifugeD all of the oil used by the engine through a centrifuge20.for the oil purifier the water content of the oil is continuously__ D and when apre-set maximum level is reached a total discharge function is automatically actuated AchargedBcompensatedCcomputedD monitored21disinfector used in the sewage biological treatment plant usually is __CA chlorineB ozoneC hypo-calcium chlorideD calcium oxide22in china the administration for implementing SOLAS convention is___BA the harbor bureauB the government of the flag state(MSA)C the ship classification societyD ship company23the minimum height of the head tank may be based on maintaining __D of fresh water in the heat exchanger above that of the sea water to ensure that in the even t of a small internal leak developing sea water cannot enter the fresh water system.

During the suction stroke, the diesel engine admits air only, but the gasoline engine admits a combustible mixture of air and gasoline. After compression, a fine spray of fuel injected into the diesel engine cylinder is ignited by the heat in the cylinder. A gasoline engine needs spark plugs to ignite the combustible mixture in the cylinder. The compression ratio of a diesel engine is higher than that of a gasoline engine. So a diesel engine is bigger than a gasoline engine.2.Xiao Wang is a cadet of the engine department, who just graduated from ShanghaiMaritime University. How do you introduce all the engine room to him?I will introduce the engine room to him in this way: This is the engine room. It is below the first deck on board .There are many machines and equipment in it, including a main engine and a lot of auxiliary machines. This is the economizer, standing just in front of the door .Down the staircase, there is a boiler. Going down some more, you will find a passage leading to the steering gear room. Moving down another flight of stairs, you will come to the level of main engine cylinder heads. Up from there, there are diesel generators. The fresh water generator is also on he same level. As the heart of a ship, the engine room should be kept in good order.3.Xiao Zhang is a three-year student majoring in marine engineering from ShanghaiMaritime University.How do you introduces the equipment and machinery in the engine room to him?I will introduce the equipment and machinery in the engine room in this way: There are many kinds of machines in the engine room. The main engine is the heart of the engine room. It supplies power for the vessel’s propulsion. Boilers are used for producing steam. A fresh water generator is used to produce fresh water from seawater. An air compressor is to supply compressed air. Steering gears are for the control of the ship’s course. All the machinery and equipment should be maintained in good order.4.Look at the illustration and say something about the disposal of the shafting anddiesel engine.I will say something about the disposal of the shafting and diesel engine. The main diesel engine is with a thrust shaft as an integral part. The thrust is bolted to an intermediate shaft. The intermediate shaft is supported by intermediate tunnel bearings. The sterntube bearing supports the tailshaft and part of the propeller weight. Sterntube seals are fitted at both ends of the tailshaft. The shafts, shaft bearings and probability make up the transmission system on board a vessel.5.Look at the illustration and say something about the probability of disposal ofmedium-speed and high-speed diesel engine.Medium-and high-speed diesel engines can be arranged as single-engine propulsion. But they are probably arranged as two-, even three-or four-engine propulsion. The illustration shows a kind of four-engine propulsion. These engines are connected with a reduction gear. Through the reduction gear, the propelling speed is reduced and the torque is increased. One of the advantages of this arrangement is that compact systems can be used.6.Look at the illustration and say something about structure of the main engine.This is an illustration of the structure of a main engine. The main engine consists of two parts: the moving parts and fixed parts. The moving parts include piston, crankshaft, and connecting rod. The fixed parts are bedplate, frame, cylinder, cylinder cover and main bearings. The bedplate, frame and cylinder block are held together by long tie rods. The connecting rod connects the piston with the crankshaft. The piston moves up and down in the cylinder. On the top of the cylinder, there is a cylinder cover. The exhaust valve, inlet valve and injector are installed on the cylinder cover.7.Look at the illustration and say something about stress status of the moving parts.This picture illustrates the stress status of the moving parts of an engine. The moving parts are stressed by two major forces. One is the compressive force from the gas in cylinder. The other is the inertia force of the moving parts. The resultant force of the two can be divided into Force N and Force S. Force S compresses or stretches the connecting rod. And it can be further divided into Force T and Force K. Force K exerts a bending stress on the crankshaft.8.Look at the illustration and say the type of piston head shape in diesel engine.This picture illustrates the shape of a piston head. There are four piston ring grooves in the head. The top of the piston head is concave, like a bowl. This shape is favorable for the mixing of fuel and air. It is also for the free expansion of the head after being heated. The type of this piston is probably a crosshead type.9.Look at the illustration and say the types of piston ring.This picture illustration various types of piston ring. The first one in the picture is the section of a rectangular ring. This kind of piston ring is most common for gas sealing. The second one is a diagonal cut piston ring. It is commonly used for oil distributor ring. The third one is a kind of piston ring with one inner-side chamfer.The fourth one is a twisted ring. And the fifth one is with an oval shape at the outer side. It is particularly used for the running-in period of a new piston.10.Please describe the lubricating mode of main engine.There are two different lubricating modes of main engine. One is for lubrication of the cylinders. The other is for bearing lubrication. The cylinder oil is usually provided by small pumps, known as mechanical lubricators. The oil should be supplied in small quantities. But the method of nearing lubrication is quite different. It is provided by forced feed system. It provides a sufficient supply of oil to all bearing. Lubrication of the main engine can reduce friction.11.Talk about the working principle of purifier according to the picture given.The picture shows the working principle of a purifier on board. It works on the principle of centrifugal separation. In a purifier, there are separation discs and outer periphery with a series of holes. When oil is pumped into it, the centrifugal force causes water to be forced to the outer periphery. A cylindrical interface is formed between the water and oil. The oil is forced inward and up to the clean oil outlet. By this way, a purifier can remove water from fuel oil.12.Talk about the working principle of oily water separator according to the picturegiven.The picture shows the working principle of an oily water separator. It works on the principle of gravity separation. When operated, the oil water separator is first filled with clean water. The oily water mixture is then pumped into the coarse separating compartment. Here some oil will separate and rise into the oil collection space. The remaining mixture now flows down into the fine separating compartment. More oil will separate out. The almost oil-free water passes into the central pipe and leaves the separator unit. The oil content in the water may be 100 ppm or less.13.Talk about the anti-pollution equipment on board ship.Anti-pollution equipment is necessary especially for ocean-going ships. The equipment includes the oily water separator, the incinerator and the sewage treating system. The oily water separator is used to treat the bilge water before discharging it overboard. The incinerator is used to burn oil wastes and some solid wastes on board. The biological sewage treatment plant is used to treat the sewage on board. These devices perform their duties to prevent pollution from ships to the sea. We should take great care of them. We should ensure that they all meet the requirements of the MARPOL Convention.14.Talk about the operation of the ballast system.The ballast system is used to bring the ship’s drafts into a seaworthy condition.Water can be drawn from any tank or the sea, or be discharged to any other tank or the sea. By this way, it can trim the vessel as required. Combined or separate mains for suction and discharge may be provided. We must operate the ballast system according to the international and port regulations. Water from CBTs (clean ballast tanks) or SBTs (segregated ballast tanks) can be discharged directly.Ballast water from fuel oil tanks should be discharged overboard through an oily water separator.15.Talk about the operation of the bilge water system.The operation of the bilge water system is an important routine work. It needs great care. The discharge of bilge waer must meet relevant requirements about pollution prevention. The bilge water should be treated by an oily water separator before being discharged overboard. The oil content limit should not exceed 15 ppm. The duty engineer should discharge the bilges before handing over a watch.The operation must be reported in the Oil Record Book. It should also be reported to the Chief Engineer. And the relieving engineer should check the bilge level when taking over a watch.第三章驾机联系munications with officersCommunications between the engineers and deck officers are very important.Lf the communication fail, accidents may happen.While they are keeping watch, they will communicate with each other by telephone. For example, the duty officer will inform the duty engineer when to stand by engine, when to check out telegraph and when the ship will arrive at the port.Before the engineer gives the main engine a trial on power, he should inform the officer.While testing the steering gear，the engineer will report the rudder angle to the bridge.Lf anything unexpected happens, they will notify each other as soon as possible.2.Noon reportA noon report must be written every day .Lt is a table with three columns.The first column is for daily performance data.Here we should enter some data concerning the main engine, ship and voyage.The second column is for remarks of the Chief Engineer.And the third one should be filled in with the working hours of the main and auxiliary engines.3.Take over watchTake over an engineering watch is an important procedure in watch-keeping .The relieving engineer should be in the engine room 15 minutes ahead of time.Before taking over watch，the relieving engineer should check various things.He should read the standing orders and special instructions of the Chief Engineer.He should be aware of all work being performed on machines and systems.Then he should take a tour around the engine room.He should check the level and condition of fuel tanks, lube oil tanks, water tanks and bilges.He should check all temperatures and pressures of various working systems.He should check the running conditions of the main and auxiliary engines.When every is found in good condition, the relieving is considered completed. 4.Before handing over an engineering watch, the engineer to be relieved shouldrecord all the incidents happened during his watch.He should tell the relieving engineer whether there are any special instructions, all work being performed on machinery and systems.He should tell the relieving engineer the liquid levels and conditions of various tanks being used .If the ship is in port, he should tell the relieving engineer the communication channel with the shore personnelAnd he should tell him all other things concerning the safety and environmental protection .5.Standby engine before departureWhen standing-by engine before departure ,we should do various things.We should check various systems of the main engine .We should warm up the main engine .We should prime the lube oil pump and vent the air from the system .We should start the lube oil pump and make sure that lube oil supply is in order.We should pump up the starting air reservoirs to their maximum pressure.We should check the reversing and control gear of the main engine .We should engage the turning gear and give the engine at least one complete turn.After informing the bridge ,we will give the main engine a brief trial on power ahead and astern .Finally ,we will ring ―stand-by‖ on the engine telegraph.6.Standby engine after sailing.(1)When do you begin standing by engine?(2)How do you stand by engine?After a period of sailing, a ship will arrive at a port.We should begin standing by engine before arriving.The starting air receivers must be pumped up to be read for maneuvering.Some control modes must be changed over from automatic to hand control.About one hour before engine movements, heavy oil should be changed over to diesel.The starting air system should be drained.Lf permissible, a test reversal of the engine should be carried out before arrival in congested waterways.7.Measures to be taken by duty engineer at rough seaWhen sailing at rough sea, the ship will pitch and roll violently.We should pump up the slack tanks and secure some movable things.The main engine speed may exceed the maximum allowable RPM because the propeller may be above the sea surface.The ship’s speed may be reduced because of greater resistanc e.So we should closely observe the working condition of the main engine.And we should get ready to any emergency conditions.8.Actions to be taken after ―Finished with engine’ ‖.(1)When do you begin finishing with engine?(2)How do you finish with engine?Afte r the bridge gives the order ―Finished with engine‖, we begin finishing with the engine.We should check various control levers.We should shut various valves and open various cocks.We should gradually reduce the cooling water temperature over a period of 8 hours.And we should turn the main engine through 3or 4 turns at first.Then we should turn the main engine through one turn at interval during cooling.9.Talk about the steering gear testingSteering gear is one of the key equipment on board.It is u sed to control the ship’s course.Both main and auxiliary steering gears should be tested using the emergency power supply.Alarms should also be checked for correct operation.This job should be done before departure from or arrival at a port.Lf requested by the port state control and officer, testing should also be done.While testing the steering gears, the deck officer and the engineer should work together.The rudder angle should be check and the system be tested.Any error or malfunction if found should be corrected.10.Actions to be taken in the case of the trial of main engineThe main engine should be tried to ensure its good working order.Before the trial, we should warn up the engine.We should engage the turning gear and give the engine at least one complete turn.We should open the scavenge drains.We should ask the bridge for permission to test the main engine.After getting permission from the bridge, we start the engine on air.Then we close all indicator cocks.We will give the engine a brief trial on power ahead and astern.11.Talk about engine room orders.Engine room orders are mainly standard engine orders.―Standing by engine‖ requires that engine room personnel get fully ready to manoeuvre .―Full ahead‖ means the maximum manoeuvring engine revolution for forward propulsion .―Full astern‖ means the maximum manoeuvring engine revolution for astern propulsion .And other engine orders include ―half ahead‖ ,‖half astern‖, ―slow ahead‖, ―slow astern‖ ,‖dead slow ahead‖ and ―dead slow astern‖ .―Finished with engine‖ means that moment of engine is no longer required .Engine orders are transmitted between the bridge and engine room through the telegraph .12.Talk about the telegraph in engine roomThe telegraph in the engine room is very important device.It is installed on the control console.Its movement is transmitted to the telegraph on the bridge.The bridge and the engine room use this system to communicate engine movements.It is usually used when the ship is going into or out of a port.The telegraph control lever has four ―ahead‖ and four ―astern‖ positions with the ―stop‖ position in the middle.第四章应急用语1、Describe briefly one of the main engine breakdown cases you experienced orheard..(1)the case.(2)actions taken in that case(3)your comments as to the actions.I have heard of a case of main engine trouble （just an example）.During navigation, the engine room alarm

Cell tops must be kept The hoisting of the cargo is effected by a hoisting winch driven by ahydraulic motor that provides a constant torque in both directions of rotation and at all speeds within the regulation range of the motor. The winch is equipped with a mechanical belt brake that acts on the outside of the rotating motor housing. During operation, the brake is released by means of oil pressure which compresses a spring. The crane jib is raised and lowered by means of a luffing winch is constructed in a similar manner to the hoisting winch.The pumps are axial piston pumps and are driven by a common 3-phased asynchronous motor at a constant speed of rotation. The capacity of the pump is changed by turning theswash-plate. The crane is turned by a hydraulic motor of the same type as that describedabove, in that the rotor turns a pinion which engages with a toothed ring on the crane housing.An oil cooler is used to remove the heat generated in the oil during the operation of the crane. The system is also provided with a pre-heater for heating the oil in cold weather. If the temperature of the oil reaches 85C, a thermostat in one of the oil lines switches off the electric motor.Pressure relief valves are built into the system to protect the system and the crane against excessive loads. All moving parts in the hydraulic system are lubricated by means of the oil in the system..The crane housing, which is a welded construction on a rigid base-plate, contains all the mechanical machinery, the hydraulic system and the electrical equipment. The top of thecrane housing and the jib carry blocks for wires for the hoisting of the cargo and the raising of the jib. All of the blocks have enclosed ball bearing.75.Which of the following is true about the hoisting of the cargo?A. an electric motor provides a constant torque.B. an hoisting winch is used.C. a mechanical brake acts on the hoisting cable.D. All of the above are true.76.The pumps _____.A. are driven by variable speed electric motorsB. turn the craneC. may deliver variable capacity by turning the swash plateD. B and C are true77.Which of the following is true about the oil in the system?A. It can be cooled in a cooler.B. Its temperature can exceed 85 degrees centigrade in no account.C. It can be used to lubricate moving parts.D. All of the above are true.78.Which of the following is true?A. The mechanical brake is released by means of a strong spring.B. At least three hydraulic motors are fitted to the system.C. The crane housing is of forged construction.D. The blocks are installed on the base-plate.三、中译英（共2题，请将答案写在答题纸上）79.主机3、4和7号缸套吊出检查和测量。
