关联题（136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 pin.s. 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. Alladjustments 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 maintenance schedule?A. The one between the cam and the tappet roller.B. The 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.AACCPassage 2Compressor cleaning during engine operationThe compressor may be cleaned by water injection during the engine operation. The cleaning process will have good results as long as the deposit formation has not gone too far. In ease a very thick hardened crest of dirt the compressor has to be dismantled for cleaning.In this method of cleaning the water is not acting as a solvent but instead removes the deposits mechanically by the impact of the water droplets. It is therefore recommended to use clean water without additives. The water should not contain any additives which might remain on the compressor blades.Periodically cleaning of the compressor (Fig. 4-2) prevents or delays excessive build-up of dirt but in no way replaces the usual overhauls where the turbocharger is completely dismantled.The turbocharger is provided with a water container (1). During the cleaning procedure the container is pressurized with the charge air (2) and from where the water is forced to the compressor inlet (3).1. Which of the following statements can be used to clean the compressor with the engine running?A. Water droplets Water with additives C. Charge air D. Hard crust2. What principal is used in this method of cleaning?A. The cleanser solves the deposits.B. The cleanser melts the deposits.C. The cleanser beats the deposits mechanically.D. The high pressure of the cleanser removes the deposits.3. Which of the following statements is not correct?A. The compressor needs regular cleaning.B. Periodical cleaning of the compressor contributes to reducing build-up of dirt.C. It’s not necessary to dismantle the turbocharger if periodical cleaning of the compressor is performed.D. Additives should better be avoided during the cleaning process.4. The cleaning water should not contain any additives, because_____.A. they may delay build-up of dirtB. they might remain on the blades of the compressorC. they may be forced to the compressor inletD. they are not good solventsACCBPassage 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) . The 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 -100℃. The second stage is supplied with water coming from the LT water system and cools the charge air further till the required temperature of approx. 50℃. 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 TEMPERA TUREC. 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 receiverBBCDPassage 4The vibration damper serves to reduce the torsional vibration generated by the crankshaft. The damper consists of a housing and a free rotating inertia ring supported by an axial bearing. It forms a totally enclosed unit. The free space between inertia ring and damper housing is filled with a high viscous fluid. When the crankshaft rotates at constant speed, the inertia ring will follow this movement. The combustion pressure exerted on each piston generates vibration in the crankshaft, and each variation generated by such a vibration will affect the movement of the inertia ring. The resulting shift of the ring to the damper housing is opposed by the viscous fluid and the vibration will be reduced.The energy, absorbed during the process, is converted into heat and then radiated to the surrounding air. Hence, proper ventilation of the damper is essential.The viscous damper fluid is during engine operation subjected to ageing and the fluid becomes more viscous. In sending fluid samples on a regular base to the damper manufacturer the rate in reduction of the viscosity can be determined. As sampling interval time is 6000 hours advised. Dampers with a too high fluid viscosity may cause crankshaft breakdown.The damper cover has two filling holes located 180o opposite each other and closed by screw-in filler plugs. If one of these plugs is accessible, a fluid sample container can be screwed in and a sample taken with the damper in place. On a spare damper, sampling must be effected with the damper in the vertical position.For liquid sampling, a special kit can be ordered from Stork-Wartsila Diesel.1. The general description of the vibration damper tells us that_____.A. the free space between inertia ring and damper housing is filled with a low viscous fluidB. when the inertia ring moves at constant speed , the crankshaft follows this movementC. the damper is made up of a housing and a free rotating inertia ringD. no ventilation of the damper is necessary as the vibration reduction process absorbs little energy2. Which of the following statements is not true about maintenance of the viscous damper?A. Sampling interval time for determining the quality of the fluid is 6000 hours.B. For liquid sampling, a special kit can be used.C. On a spare damper, sampling must be effected with the damper in place.D. The viscous fluid in a damper becomes more viscous as time goes by.3. During the engine operation, the vibration damper can_____.A. transfer the energy of the engineB. absorb the combustion heatC. oppose the crankshaft rotatingD. reduce the vibration of the crankshaft4. According to the passage, we learn that two filling holes in the damper cover are used _____.A. to recharge the fluidB. to ventilate the damperC. to fit the containerD. to take the sampleCCDDPassage 5The vibration damper employs a high viscous fluid to oppose the shift of the inertia ring to the damper housing. It is necessary to get samples to determine the rate in reduction of the viscosity. The steps to draw off the sample are as follows(Refer to the Fig. 4-3):1. Turn the engine until the drain plugs are easy accessible. Do not unscrew the drain plug until the damper is luke warm (approx. 40o C ).2. Carefully tap the locking of the upper drain plug backwards, using a punch, and unscrew the threaded plug. Do not yet remove the plug!3. Unscrew one cap nut from the (plastic) liquid container.4. Remove the drain plug and screw the liquid container instead.5. Remove the outer cap nut from the liquid container. Make sure that no machine oil or dirt can enter the liquid container!6. Screw the outer cap nut again, once the liquid has reached the open end of the liquid container. The filling-up period of the liquid container may take from a few seconds up to more than an hour, depending on the liquid condition.7. Unscrew the liquid container from the damper and fit the drain plug using a new joint ring (supplied with the mounting kit).8. Fit the second cap on the liquid container.If no sample can be taken in this way, you can proceed as follows:- If still no liquid appears after a while, remove the second drain plug, too.- Supply nitrogen of 3.5 bar maximum pressure through the open filling hole.If no nitrogen is available, air may be used, provided this air is properly filtered and dry.- Once the liquid has reached the open end of the liquid container, cut off the supply of nitrogen and screw the cap on the liquid container.- After the nitrogen supply has cut off, unscrew the liquid container, screw the second cap and fit both drain plugs.If a liquid sample cannot be obtained this way either, it can be assumed that the damper liquid has thickened to an inadmissible value, necessitating the replacement of the damper.1. According to the passage, we can learn that_____.A. before using the container to draw off the sample, both ends of it are closedB. the liquid container must be washed with machine oil before samplingC. liquid sampling must take more than one hourD. two liquid samples should be taken every time2. If the liquid sample cannot be taken any way, it means_____.A. nitrogen pressure is too lowB. the quantity of the damper fluid is insufficientC. the viscous fluid in damper becomes too thickD. the method of liquid sampling is incorrect3. Which statement is tree about the sampling process?A. The drain plug can be unscrewed regardless of the damper temperature.B. The drain plug should not be removed until one cap nut from the liquid container is unscrewed.C. The outer cap nut must be screwed before the liquid reaches the open end of the liquid container.D. The drain plug can be fit by using the old joint ring.4. If no sample can be taken by removing the first drain plug, then which of the following is done?A. The second drain plug should be removed too.B. A pressure of 5.3 bar should be applied.C. Clean and damp air is used instead of nitrogen if the latter is not available.D. The nitrogen supply continues when the liquid has reached the outer end of the liquid container. ACBAPassage 6At the first start, listen carefully for possible jarring(刺耳的) sounds. If anything is suspected, stop the engine immediately, otherwise stop the engine after 5 minutes’ idling. Check at least the temperatures of the main and big end bearings and of all other bearings which have been opened. Make visual inspection from below to the cylinder liners and piston skirts which have been opened. If everything is in order, restart.Check that there is no leakage of gas, water, fuel or lubricating oil. Especially observe the fuel lines, HP fuel pumps and injectors. Watch the quantities emerging from the leak oil pipes!Check that the starting air manifold is not hot at any cylinder (leaky starting valve may cause explosion!After overhaul, the following instructions are important:- check pressure and temperature gauges.- check the automatic alarm and stop devices.- check the pressure drop over the fuel filter and lubricating oil filter.- check the oil level in the oil sump/oil tank. Estimate the condition of the oil.- check the de-aerating of the engine circulating water system.- check the quantity of fuel leak.- check the telltale holes for leaks.- check the circulating water quality- check the cylinder pressures.- listen for jarring sounds.- check the crankcase pressure.- check the starting air manifold.Running-in is mainly intended to let piston tings "wear" to fit properly in the cylinder liner.Do not continuously run at constant load during the running -in process ( Fig. 4-4).It is important to vary the load several times. The ring grooves in the piston will have a different tilting angle at each load and consequently the piston ring has a different contact line to the cylinder liner wall.1. Paragraph 1 tells us that_____.A. if we hear vibration sounds, we should stop the engine quickly, or allow it to operate at low speed for5 minutes, then stop it and check everythingB. if we hear vibration sounds, we should stop the engine quickly, otherwise the engine will be stopped automatically after 5 minutesC. if we hear explosion sounds we should stop the engine then check everythingD. if we hear surging sounds, we should stop the engine immediately otherwise after 5 minutes the engine will be destroyed2. After overhaul, following instructions are important except_____.A. release air from the engine circulating water systemB. treat the circulating water if necessaryC. make sure the pressure drop is enough besides the fuel filterD. make sure the quantity of lube oil meets the requirement3.

When dealing with engine troubles, _____.A. no leakage of lubricating oil should be checked_____.B. quantities of oil emerging from the leak oil pipes must be watchedC. quality of the leak oil must be watchedD. the number of the leaking fuel lines should be checkedACDBPassage 7This sequence of events is made possible by substituting ports in the bottom of the cylinder wall for the inlet and exhaust valves. There are two groups of these ports, one for exhaust and the other for scavenging air, usually on the opposite sides of the cylinder, but in some designs both groups are arranged on the same side. The exhaust ports connect with the exhaust manifold, while the scavenging ports communicate with the scavenging air receiver in which low-pressure air is stored. The exhaust ports are slightly higher than the scavenging ports, so that they are uncovered by the piston while the scavenging ports are still closed.(The following 2 questions are based on the passage above. )1. From the paragraph above, we know that_____.A. In general, both exhaust ports and scavenging air ports are on the opposite sides of the cylinderB. The exhaust ports are on the opposite sides, but the scavenging air ports are on the same sidesC. The scavenging air ports are on the opposite sides, but the exhaust ports are on the same sidesD. Two groups of parts are never arranged on the same sides2. According to the above paragraph the exhaust ports link with_____.A. the exhaust valvesB. the scavenging air receiversC. the exhaust manifoldD. the scavenging portsThe engine is also provided with a governor which is designed to regulate the engine' s speed by adjusting the quantity of oil injected. When the engine runs at a speed higher or lower than that is set, the governor will act automatically reduce or increase the fuel oil supply so that the engine can be adjusted.( The following 2 questions are based on the passage above. )3. From this paragraph we can understand that_____.A. if the engine runs at a speed higher than that is set, the governor will increase the fuel oil supplyB. if the engine runs at a speed higher than that is set, the governor will decrease the fuel oil supplyC. the governor will not act until the engine runs at speed lower than that is setD. the governor regulates the engine's speed by adjusting the fuel oil injection4. The engine governor is used for_____.A. adjusting the fuel oil injection qualityB. adjusting the engine speedC. keeping the engine at higher speedD. keeping the engine at lower speedACBBPassage 8The lubrication system of an engine provides a supply of lubricating oil to the various moving parts in an engine. Its main function is to enable the formation of a film of oil between the moving parts, which reduces friction and wear. The lubricating oil is also used as a cleaner and in some engines as a coolant. The usual method of bearing lubrication is by forced feed system, which supplies oil to all bearings, so that a film of oil is maintained on the journal and bearing surfaces.(The following 2 questions are based on the passage above.)1. The forced feed system is put into use in order to _____.A. supply oil to all parts of the engineB. lubricate the bearing and the pistonC. maintain a film of oil on the journal and bearing surfacesD. maintain a film of oil on the piston surfaces only2. What is the function of lubricating oil?A. Formation of a film of oil between the moving parts, which reduces friction and wear.B. Used as a cleaner.C. As a coolant in engines.D. All of the above.Fresh water is used for the cooling of the cylinder jackets and covers of the main engine, whereas the various cooling liquids which circulate the engine are themselves cooled by sea water, such as, sea water is used for the cooling of the oil in the lubricating oil cooler as well as the fresh water. In an emergency situation, for example in the event of damage to a fresh water cooler or generator, the sea water pumps can be used to supply sea water to the fresh water cooling system, merely by removing the blind-flanges.(The following questions are based on the passage above. )3. In which situation we should use sea water system instead of fresh water system?A. When sea water pumps are damaged.B. When sea water cooler is damaged.C. When fresh water pumps are damaged.D. The blind-flanges are broken.4. The word “merely” in this paragraph could best be replaced by_____.A. onlyB. necessaryC. butD. ifCDCAPassage 9Because the exhaust gas driven turbo-blower cannot provide enough air at low engine speeds, the pressurized air should be cooled to increase the charge air density. As the air passes through the charge air cooler, its temperature may be reduced and moisture condensed, with the condensate in danger of being carried into the engine. So a water separator should be mounted beneath the bottom part of the engine inlet manifold.(The following 2 questions are based on the passage above.)1. A water separator is used in order to _____.A. keep the air from being carded into the engineB. keep the moisture from being condensedC. keep the danger from being carded into the engineD. take away the condensate from the air2. Why should we use a charge air cooler?A. In order to increase the charge air temperature.B. In order to increase the charge air pressure.C. In order to reduce moisture condensed.D. In order to increase the charge air density.Lubricating oil from the compressor will pass along the air lines and deposit on them, in the event of a cylinder air starting valve leaking, hot gases would pass into the air pipes and ignite the lubricating oil. If starting air were supplied to the engine, this would further feed the fire and could lead to an explosion inthe pipelines. In order to prevent such an occurrence, cylinder-starting valves should be properly maintained and the pipelines regularly drained. Also oil discharged from compressors should be kept to a minimum, by careful maintenance.(The following 2 questions are based on the passage above.)3. Which of the following may cause an explosion according to the passage?A. Starting air cannot be supplied into the engine.B. Air starting valve leaks and starting air is supplied into the engine.C. Cylinder-starting valves are properly maintained.D. Oil discharged from compressors is kept to a minimum.4. In order to avoid igniting the lubricating oil and leading to an explosion in the pipelines, _____.A. pipelines should be regularly drainedB. cylinder-starting valves should be properly maintainedC. oil discharged from compressors should be kept to a minimumD. A+B+CDDBDPassage 10Fuel oil is thought to be one of the main factors, having much to do with the operation and maintenance of an engine. The fuel oil system for a diesel engine can be considered in two parts: the fuel supply and the fuel injection system. When the atomized fuel is injected into the combustion space, ignition is not altogether instantaneous, a definite time lag being measurable between the time of injection and ignition. The period of ignition lag depends, among other factors, on the ignition quality of the fuel and the temperature of the compressed air.(The following 2 questions are based on the passage above.)1. This paragraph tells us that_____.A. ignition takes place before the injection of the atomized fuelB. ignition takes place simultaneously with the injection of the atomized fuelC. the period of ignition lag depends only on the quality of the fuel and the temperature of the compressed airD. the ignition quality of the fuel and the temperature of the compressed air are the two main factors determining the period of ignition lag2. “instantaneous瞬间的” in the passage probably means_____.A. simultaneous（同时的）B. afterC. beforeD. whenThe crankshaft is built up, the forged main bearing journals being shrunk into cast steel crank throws. The crank throws are displaced from each other to obtain the same number of degrees between the different crank throws. The alignment of the crankshaft in the bedplate should be checked at intervals to ensure that the shaft is not subjected to additional bending stresses, which, under extreme conditions, may cause crankshaft failure.(The following 2 questions are based on the passage above.)3. What does the word “alignment” mean in this passage?A. the bedplate is checked at intervalsB. to ensure that the shaft is not subjected to additional bending stressesC. to obtain the same number of degrees between the different crank throwsD. arrangement in a straight line4. The number of degrees between the different crank throws should beA. all the sameB. a little bit differentC. smallerD. largerDADAPassage 11During overhaul the safety roles have to be observed as required in order to prevent the danger of accidents. Special precaution is necessary when the engine is running with lagging removed. During overhauls, with the engine shut down, safety measures should be taken to avoid undesirable turning of the crankshaft. All pipes should be pressure-relieved before the repair work is started. Read the pressure gauges and/or check the pipes by carefully loosening the screw plugs or connections.(The following 2 questions are based on the passage above.)1. During overhaul, we have to observe the safety rules, in order to _____.A. avoid desirable turning of the crankshaftB. make all pipes pressure-relievedC. avoid the danger of accidentsD. let the crankshaft turn undesirably2. Before the repair work is started, _____.A. engine should be pressure-chargedB. the pressure in all pipes should be increasedC. all pipes should be pressure-relievedD. the air in some pipes should be relievedFresh water is used for the cooling of the cylinder jackets and covers of the main engine, whereas the various cooling liquids which circulate the engine are themselves cooled by sea water, such as, sea water is used for the cooling of the oil in the lubricating oil cooler as well as the fresh water. In an emergency situation, for example in the event of damage to a fresh water cooler or generator, the sea water pumps can be used to supply sea water to the fresh water cooling system, merely by removing the blind flanges.(The following 2 questions are based on the passage above.)3. From this paragraph, we can see that_____.A. the cylinder jackets and covers are cooled by fresh water and then by sea waterB. fresh water is used for the cooling of the cylinder jackets and covers of the main engineC. fresh water is used for the cooling of the main engineD. sea water is used for the cooling of both the fresh water and the main engine4. According to the paragraph, the term “various cooling liquids” refers to_____.A. fresh water and sea waterB. air and fresh waterC. fresh water and cooling oilD. sea water and airCCBCPassage 12The installation including expansion, preheating and pressurizing should be carried out in strict accordance with the instructions of the engine manufacturer to obtain a correct and trouble free installation. There should be no reason to carry out any maintenance to the cooling water system unless the temperatures in the cooling water system start to rise without any clear reason. Normally all inspections andmechanical cleaning of the cooling water system components are better to do at planned intervals.The circulating fresh water should be treated according to the recommendations to prevent corrosion and deposits. If the risk of freezing occurs, drain all cooling water spaces. Avoid using fresh cooling water. Save the drained water and use it again.In completely closed systems the fouling will be minimal ff the cooling water is treated according to the instructions.Depending on the cooling water quality and the efficiency of the treatment, the cooling water spaces may or may not foul over the length of time. Deposits on cylinder liners walls, cylinder heads and cooler stacks should be removed to avoid disturbance in the heat transfer to the cooling water with thermal overload as consequence.The necessity of cleaning should be investigated, especially during the first year of operation. This may be done during overhaul of a cylinder liner inspection for fouling and deposits on the liner and block. The cylinder head cooling water spaces can be checked by removing the water space plugs in the sides of the cylinder heads. The turbocharger can be checked through the inspection covers of the water spaces. The deposits can quite vary in structure and consistency. In principle, it can be removed mechanically and/or chemically.1. The sentence “The circulating fresh water should be treated ...” (paragraph 2), most probably means that the fresh cooling water should be _____.A. drained to avoid freezingB. collected when drainingC. changed at planned intervalsD. analyzed and dosage added if necessary2. Which of the following statements is true?A. The cooling water system does not need maintenance if it works normally.B. The circulating fresh water does not need special treatment when in normal operation.C. In completely closed cooling water system scale will not be formed.D. Deposits in the cooling water system may not be formed over the length of time.3. Which of the following statements about the first sentence in paragraph 1 is true?A. The engine is installed by the manufacturer free of charge.B. The engine should be warmed in advance before installing.C. The installation must be conducted according to the instructions.D. The installation may be carried out freely.4. We can _____ to find out about the scale in the cooling water space of the cylinder cover.A. overhaul the cylinder linersB. remove the plugs in the sides of the headsC. open the inspection coversD. withdraw the pistonsDACBPassage 13Mechanical cleaningA great deal of the deposits consists of loose sludge and solid particles which can be brushed and rinsed off with water. On places where the accessibility is good, e.g. cylinder liners, mechanical cleaning of considerably harder deposits is efficient. In some cases it is advisable to combine chemical cleaning with a。

(236015:第 1 章船舶主推进装置:571)A. pumpedB. chargedC. loadedD. releasedDIESELITE is a multi-functional fuel treatment containing combustion catalysts and ash modifiers. It is intended for use in diesel engines and boilers burning residual fuels. Carbon residue formation during combustion is inhibited by catalysts that lower the ignition temperature of heavy asphaltenic particles. Combustion time is consequently increases, leading to a reduction of tarry deposits and carbonaceous fire-scale.Ash modifiers combine with fuel combustion ash to raise the sinter and melting points of the ash above the engine or boiler normal operating temperatures. High temperature corrosion is minimized, reducing maintenance and extending service life. The majority of ash formed is ejected with the exhaust gases in a fire, solid state, and any ash remaining in the exhaust system is easily removed by light brushing.The conversion of fuel sulphur to potentially corrosive sulphur trioxide gas is also inhibited. Sulphur trioxide react with condensed steam in the exhaust trunking, funnel uptakes and other cooler zones to form sulphuric acid.DIESELITE is a wide spectrum additive intended for continuous use.(1) Which of the following statements is NOT true according to the passage?A. DIESELITE contains combustion catalysts and ash modifiers.B. DIESELITE is a wide spectrum additiveC. DIESELITE is a multi-functional fuel treatmentD. DIESELITE is intended for use in diesel engines only.（2）Carbon residue formation during combustion is inhibited by ____.A.tarry depositsB.ash modifiersC.catalystsD.carbonaceous fire-scale (3)According to the passage, we can learn that ___.A. DIESELITE agent should not be used continuouslyB.the ash modifiers can reduce forming ashC.DIESELITE agent can not inhibit sulphuric acidD.DIESELITE agent can not only reduce high temperature corrosion, but also reduce low temperature corrosion.(4)DIESELITE is most suitable for treating _____.A.lube oilB.diesel oilC.residual oilD.turbine oilHand control of excitation(励磁) is difficult so use is made of an automatic voltage regulator (A VR). The A VR consists basically of a circuit fed from the alternator output voltage which detects small changes in voltage and feeds a signal to an amplifier(放大器) which changes the excitation to correct the voltage. Stabilizing features are also incorporated in the circuits to avoid …hunting(振荡)‟ (constant voltage fluctuations (波动)) or overcorrecting(过调).With all types of electrical equipment cleanliness is essential for good operation. Electrical connection must be soun and any signs of sparking should be investigated. Parts subject to wear must be examined and replaced when necessary. The danger from a.c. equipment in terms of electric shocks is far greater than for similar d.c. voltages. Also a.c. equipment often operates at very high voltages. Care must therefore be taken to ensure isolation of equipment before any inspections or maintenance is undertaken. The accumulation of dirt on electrical equipment will result in insulation breakdown and leakage currents, possibly even an earth fault. Regular insulation resistance measurement and the compiling of records will indicate the equipment requiring attention. Ventilation passages or ducts may become blocked, with resultant lack of cooling and overheating.Totally enclosed machines should be periodically opened for inspection and cleaning since carbon dust will remain inside the machine and deposit on the surface. Brushgear should be inspected to ensure adequate brush pressure and the spring adjusted if necessary. New brushes should be …b edded in‟ to the commutator or slipringshape with fine glass paper. Sparking at the commutator will indicate poor commutation. This may require polishing of a roughened commutator surface.(1) Insulation breakdown and leakage currents may result from ____.A.circuitB.d irt accumulationC.e lectrical connectionD.cleanliness designed that it is possible to maintain a rather high injection pressure also at low load, without the limitation from the camshaft-controlled engine, where this would result in too high pressure at high load. Both the ‟cam angle, indication and length‟ are electronically variable. In addition, the ME engine features electronic control of the cylinder lube oil feed. With the Alpha Lubrication system, about 0.3g/bbph cylinder oil can be saved, compared with engines with mechanical lubricators. The electronic control of the engine fuel injection and exhaust valves improves low-load(2)__ is essential for good operation to all types of electrical equipment.operation, engine acceleration, and give better engine balance and load control,A.CareB.D.C voltagesC.A.C equipmentD.Cleanliness(3) What does the underlined word …resultant‟mean ?A.PunkB.T rashC.C ompoundD.Relevant(4) Which of the following statement is wrong?A.Inspection and cleaning are needed by totally enclosed machines.B.T he danger from a.c. equipment is far less than for similar d.c. voltages.C. B rushgear should be inspected to ensure adequate brush pressure.D.Hand control of excitation is difficult so use is made of an automatic voltageregulator.Camshaft-controlled diesel engines have been the state of the art ever since the birth of reciprocating machinery and have been refined and developed ever since. However, a mechanical cam is fixed once made and, in spite of various mechanical and hydraulic add-on devices like VIT, etc, timing control possibilities are limited with mechanical cams. Not least fuel injection pressure control and variation over the load range have limitations with a cam-controlled engine. Therefore, the main purpose of changing to electronic control is to ensure fuel injection timing and rate, as well as the exhaust valve timing and operation, exactly when and as desired. Especially with respect to the fuel injection rate, the control system has been so leading to longer times between overhauls, also by implementation of enhanced diagnostics systems. It will give lower fuel consumption, lower cylinder oil consumption and, not least, better emission characteristics, particularly with regard to visible smoke and NOx.(1) What is the passage talking about?A.NOx emissionB.M E engineC.A lpha LubricatorD.VIT(2) What can be inferred according to the passage?A.For traditional engine, the pressure control of fuel injection is harder than thetiming control.B.W ith ME engine, the timing of exhaust valve can be controlled.C.T he traditional engine will have high injection pressure when at low load.D.For traditional engine, the pressure control of fuel injection is easier than thetiming control.(3) Which one of the following is true according to the passage?A.For ME engine, the cylinder oil supply is electrically controlled.B. T he ME engine has no cylinder lubricator.C.T he ME engine Alpha Lubrication system.D.For ME engine, the cam is mechanically variable.(4) Which one of the following is not one of the merits of ME engine?A.Lower charge air pressureB.M ore accuracy and flexible control of engine.C.Lower NOx emissionD.Lower fuel consumption.The Protocol on Preparedness, Response and Co-operation to Pollution Incidents by Hazardous and Noxious Substances (OPRC-HNS Protocol), 2000, has achieved enough ratification for entry into force on 14 June 2007.

Assertions are sometimes made by cargo interests that rust on a particular shipment is normal and will not affect its market value. Such comments should be disregarded.In all cases where a steel cargo is found to be rusty, it is imperative that remarks are made on the bills of lading, irrespective of the apparent severity of the rust. The bills of lading should also be claused to reflect any physical pre-shipment damage to the steel and/or wrappers.Selecting the most appropriate clauses to describe pre-shipment damage is not always easy, and the attending surveyor should be consulted for advice. Care must be taken to confine the remarks only to the apparent condition of the steel. Comments such as “damaged by stevedores”and “loaded during rain” have no value.Similarly, words such as “slight”, “superficial”, “partial” and “atmospheric” may be open tomisinterpretation and should never be used. Wherever possible, the remarks should be specific.69. The carrier will be relieved of the responsibility if ______.A. he fails to identify cargo’s pre-shipment damageB. he fails to clause mates’ receipt and bills of lading.C. he identifies cargo’s pre-shipment damage and make proper remarks on mate’s receipt andbills of lading.D. he makes assertion that the rust is normal and will not affect its market value.70. Under what condition should the bill of lading be claused?A. when pre-shipment damage is seriousB. so long as a steel cargo is found rustyC. so long as its physical pre-shipment damage is not easy to describeD. You should consult the attending surveyor for advice about it.71. What do you think of the remark “partial damage to wrapper”?A. It’s easy to cause misunderstanding.B. It has no value.C. It can not exempt the carrier from the liability if actual damage is found at the destination.D. All of the above.72. The best title of this passage may be ______.A. Carrier’s rights, limitations and immunitiesB. Cargo’s pre-shipment damageC. Clausing bills of ladingD. Value of remarks第二组：During an anchoring operation, a vessel's anchor was run out under gravity to 6 shackles, checked and finally adjusted to 9 shackles on deck. A crew member who was on the forecastle but not directly involved with the anchoring operation, was enveloped by the resulting dust/debris cloud and later complained of irritation to his eyes requiring treatment from the shore doctor to alleviate it.When engaged in anchoring, there is always a hazard from dust and debris flying off the anchor cable. With this in mind, all persons in the vicinity should be wearing suitable personal protection including eye protection. The chief officer in charge must always ensure that neither himself nor any other crew member stands in line with the anchor cable either in front or behind the cable lifter, as there have been fatalities in the past caused by cables which have gone out of control.If there is any doubt as to the efficiency of the brake, anchors should always be lowered in gear, using the windlass motor and never allowed to run so fast as to overheat the brake.73.From the first paragraph, we can get that ______.A. the crew member was directly engaged in anchoring operation.B. the crew member was enveloped by anchor chains.C. the crew member had been injured by anchor chains.D. the crew member had foreign material in his eyes.74.“Fatality”in the second paragraph means ______.A. injuryB. deathC. fractureD. fate75. When engaged in anchoring, what you should not do is ______.A. to stand near behind the windlassB. to wear gogglesC. to wear glovesD. to lower anchors in gear if there is no doubt as to the efficiency of the brake76.Which one of the followings is not mentioned in the passage?A.

轮机英语UNIT2 how does a diesel engine work
At this low speed the engine requires no reduction gearbox between it and propeller.
The four-stroke engine (usually rotating at medium speed, between 250 to 750 rev/min) is used for alternators and sometimes for main propulsion with a gearbox to provide a propeller speed of between 90 to 120 rev/min.
The burning of the fuel adds more heat to the air charge, causing it to expand（膨胀） （膨胀） and force the engine piston to do work on the crankshaft（曲 （ 轴） which in turn drives the ship’s propeller(螺旋桨 螺旋桨). 螺旋桨
Fuel injector Cylinder Piston
Exhaust port
Scavenge port
Connecting rod Crank
Scavenge (a)
Compression (b)
Injection (c)
Exhaust (d)
The two-stroke cycle begins with the piston coming up from the bottom of its stroke, i.e. bottom dead center (BDC), with the air inlet ports or scavenge ports(扫气口 in the 扫气口) 扫气口 sides of the cylinder being opened (Fig. 1-a)).
