With good management, to facilitate subsequent starting from cold, the fuel system of large boilers will have been flushed through with diesel oil when the boiler was on light duty immediately prior to being secured. When burning such diesel fuel it is essential for safety that only the correct (small) burner tip should be used. It should be kept in mind that if fire does not light, immediately shut off fuel and vent furnace.Complete ignition of fuel in the furnace is essential. The burner flame, the smoke indicator and the funnel should be frequently observed. With satisfactory combustion, the flame should appear in candescent （白热的）with an orange shade at the flame tip, and a faint brownish haze should show at the funnel. If on first ignition the flame is uncertain, badly shaped and separates from the primary swirler, momentary opening or closing of air register may correct.75.

If only one or two cylinders fail, and the engine is not f ully loaded, the crankshaf t rev/min does not decrease, the reason being that the governor ensures that the remaining cylinders are loaded to a correspondingly great er extent. If the engine is already f ully loaded, the cylinders that are working normally become overloaded causing a smoking exhaust and higher exhaust temperatures etc. The load must always be reduced until the f ailure has been located and recti f ied. The reasons f or a cylinder suddenly working at reduced load, or failing completely, may be :1. a def ective or blocked f uel injection valve.2.the f uel oi l pump piston seizing in the barrel. This f ailure can be ascertained by trying to move the pump‟s toothed rack.Defective f uel pumps must be changed.3.the compression being to low because of sticking , worn or broken piston rings.4 leaking inlet or exhaust valves5. no clearance in the valve operation gear.The reasons f or the crankshaf t rotating more slowly, or stopping completely,can also be:1. the f uel oil f ilter being blocked.

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.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 andcould lead to an explosion in the pipelines. In order to prevent such an occurrence, cylinder-starting valves should be properly maintained and the pipelines regularly drained. Also oildischarged from compressors should be kept to a minimum, by careful maintenance.69.A water separator is used in order to ______.A. keep the air from being carried into the engineB. keep the moisture from being condensedC. keep the danger from being carried into the engineD. take away the condensate from the air70.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.71.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.72.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+C第二组：Maintenance and OverhaulingSatisfactory and proper operation of the engine depends not only on correct manoeuvring but also on how well it is kept in order. Regular maintenance of the engine helps a lot in preventing early wear of parts and in ensuring a long service as well as the working efficiency of the engine.With various types of engines, of course, the maintenance and overhaul is different. Instruction books are to be referred to whenever necessary.The individual parts of the engine should be inspected and thoroughly cleaned at regular intervals. The periods for such overhaul work depend largely on the quality of the lubricating oil and fuel, on the load and on the efficiency of the operator in locating troubles and remedyingthem in time..During overhaul the safety rules have to be observed as required in order to prevent the danger of accidents. Special precaution is necessary when the engine is running with the 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.If some parts of the running gear are dismantled, before using the turning gear, make sure that no loose parts are jammed in the crankcase where it is easy for them to cause damage.73.According to the passage, which the following factors are involved to keep the enginesatisfactory and proper running?A. correct manoeuvringB. keep the engine in orderC. refer to the instruction booksD. all of above74.According to the passage, which the following items do influence the periods of the overhaulingwork?A. the quality of the lubricating oilB. the load of the engineC. the efficiency of the operator in locating troubles and remedying them in timeD. all of the above75.According to the passage, we should take special precaution when ____.A. the engine is running with the removal of laggingB. the engine is shut downC. pipes are removedD. the screw plugs or connections are lossened76.According to the passage, line 17 the bold and italic word “it” may propabably mean ____ .A. running gearB. turning gearC. crankcaseD. to cause damage中华人民共和国海事局2003年第3期海船船员适任证书全国统考试题(总第32期)科目：轮机英语试卷代号：803适用对象：无限、近洋航区3000KW及以上船舶大管轮（本试卷卷面总分100分，及格分为70分，考试时间为100分钟）答题说明：请选择一个最合适的答案，并将该答案按答题卡要求，在其相应位置上用2B铅笔涂黑。

A control system is a system which measures the condition of some entity and, with the information, governs the state of a variable; i.e., speed, temperature, pressure, position, etc. The open-loop system is the simplest form a control system may assume. It is distinguished from the closed-loop system by the lack of an input which measures the state of the controlled variable; such an input is called a feedback. In modern ships the open-loop system has practically disappeared and the closed-loop system which operates with a feed-back is extensively used. An information system serves the parallel function of monitoring system or plant performance. The monitoring function may serve a number of purposes; specifically it may indicate values of controlled variables to guide remote control operations, w arn ofoff-limit conditions and provide record of performance. In many cases a visual and audible alarm may be provided to warn of off-limit conditions on board ship and, associated with this, the important variables will be recorded on demand. The automatic control system can be more sophisticated by incorporating digital-processing equipment, that is, a computer. This computer is usually fed with signals from all sensors. It scans the values of the sensors and generates alarm signals for off-limit conditions, acting as a super-supervisor. Sometimes, it can even make necessary and take the necessary action to optimize performance without human intervention.69. The closed-loop system differs from the open-loop system byA. the lack of a feedbackB. the presence of a feed backC. the lack of a computerD. the presence of a computer70. A feedback is an input ____A. which governs the state of a variableB. which provides a visual and audible alarmC. which indicates values of controlled variablesD. which measures the state of the controlled variable71. The monitoring function may serve all of the following purposes exceptA. instigating corrective actionB. indicating values of controlled variablesC. warning of off-limit conditionsD. providing record of performance72. The word "off-limit" in the passage may mean .A. off-setB. off-stateC. within limitsD. beyond the limit第二组The only attention that heat exchanger should require is to ensure that the heat transfer surfaces remain substantially clean and the flow passages generally clear of obstruction. Indication that undue fouling is occurring is given by a progressive increase in the temperature difference between the two fluids, over a period of time, usually accompanied by a noticeable rise in pressure loss at a given flow.Fouling on the sea-water side is the most usual cause of deterioration in performance. The method of cleaning the sea water-side surfaces depends on the type of heat exchanger. With shell-and-tube heat exchangers, the removal of the header covers or, m the case of the smaller heat exchangers, the headers themselves, will provide access to the tubes. Obstructions, dirt, scale etc., can then be removed, using the tools provided by the heat exchanger manufacturer. Flushing through with fresh water is recommended before a heat exchanger is returned to service. In some applications, such as piston oil cooling, progressive fouling may take place on the outside of the tubes. Most manufactures recommend a chemical flushing pr6cess to remove this in situ~ without dismantling the heat exchanger.Plate heat exchangers may be cleaned by unclamping the stack of plates and mechanically cleaning the surface of each plate as recommended by the manufacturers. The plate seals may require replacement from time to time and here the manufacturers' instructions should be closely followed 73. By which of the following indication, can we conclude that the lube oil-sea water heat exchanger is unduly fouled?A. the heat exchanger lube oil inlet temperature loweringB. the heat exchanger sea-water outlet pressure riseC. the heat exchanger temperature difference between lube oil and sea water increasingD. the heat exchanger pressure difference between sea water inlet and outlet decreasing74. What is the most usual reason for the fresh water-sea water heat exchanger fouling in the sea side?A. lube oil sludge accumulating in itB. dirt and scale etc., formed on the surfacesC. deformation of the tubes and the shell or the platesD. lube oil leakage into sea-water side75. According to the passage, it is recommended that the heat exchanger side be cleaned by .A. flushing with chemical solvent without being dismantledB. brushing mechanically after being disassembledC. flushing with flesh water onlyD. flushing with clean oil only76. According to the passage, which of the following statement is not true?A. the heat exchanging surfaces should be kept substantially cleanB. the heat exchanger flow passages should be clear of obstructionC. seals for the plate heat exchanger needs to be renewed oftenD. the cleaning process of the plate heat exchanger should be done following our experiences only三、中译英（共2题，请将答案写在答题纸上）77. 在船舶以主机“正常全速”运行时，尽管速度设定及压力正常，转速逐渐下降，驾驶台控制立即转换至机旁控制。

The cause of the potential is the development of a galvanic element between the ship’s hull, sea water, and the propeller shaft/crankshaft.The oil film acts as a dielectric. The puncture voltage in the bearing depends on the thickness of the oil film. With increasing engine ratings, the specific load in the main bearing is increased. This will reduce the oil film thickness, and enable the discharge to take place at a lower voltage level.Since the hydrodynamic oil film thickness varies through a rotation cycle, the discharge will take place at roughly the same instant during each rotation cycle, i.e. when the film thickness is at its minimum. The roughening will accordingly be concentrated in certain areas on the journal surface. In the early stages, the roughened areas can resemble pitting erosion. but later, as the roughness increases, the small craters will scrape off and pick up white metal-hence the silvery white appearance. Therefore, to ensure protection against spark erosion, the potential level must be kept at maximum 80 mV, which is feasible today with a high efficiency earthing device. If an earthing device is installed, its effectiveness must be checked regularly. Spark erosion is only observed in main bearings and main bearing journals.69. According to the paragraph one, a voltage between the main bearing and journal surface isproduced by______.A. propeller rotationB. leakage from M/E electric control unitC. a galvanic elementD. friction between the main bearing and journal surface70. ______engine ratings increase, the hydrodynamic oil film between the main bearing andjournal surface is______.A. The lower/thinnerB. The higher/the thickerC. The lower/thickerD. The higher/thinner71. When will the spark erosion take place on the journal surface during each rotation cycle?A．when the film thickness is at its minimumB．when the film thickness is at its maximumC．when the engine is on its compression strokeD．when the engine is on its exhaust stroke72. During the engine room watch keeping, which equipment must be noted to ensure protectionagainst spark erosion?A．the antifouling plant B．the earthing deviceC．the main engine electric heating coils D．the shaft generator第二组：The 1978 STCW Convention was the first to establish basic requirements on training, certification and watch-keeping for seafarers on an international level. Previously the standards of training, certification and watch-keeping of officers and ratings were established by individual governments, usually without reference to practices in other countries. As a result standards and procedures varied widely, even though shipping is the most international of all industries.The Convention prescribes minimum standards relating to training, certification and watch-keeping for seafarers which countries are obliged to meet or exceed.The Convention did not deal with manning levels: IMO provisions in this area are covered by regulation 13 of Chapter V of the International Convention for the Safety of Life at Sea (SOLAS), 1974, whose requirements are backed up by resolution A.890(21) Principles of safe manning, adopted by the IMO Assembly in 1999, which replaced an earlier resolution A.481(XII) adopted in 1981.The Articles of the Convention include requirements relating to issues surrounding certification and Port State Control.One especially important feature of the Convention is that it applies to ships of non-party States when visiting ports of States which are Parties to the Convention. Article X requires Parties to apply the control measures to ships of all flags to the extent necessary to ensure that no more favorable treatment is given to ships entitled to fly the flag of a State which is not a Party than is given to ships entitled to fly the flag of a State that is a Party.The difficulties which could arise for ships of States which are not Parties to the Convention is one reason why the Convention has received such wide acceptance. By December 2000, the STCW Convention had 135 Parties, representing 97.53 percent of world shipping tonnage.73. Before the establish of the STCW78, the standards of training, certification and watch-keeping ofseafarers _____.A．were established by IMOB．were established by a famous organizationC．were established by individual governments with reference to practices in other countries D．varied widely among countries74. The regulation 13 of Chapter V of the SOLAS 1974 covered _____.Ａ．the manning of shipsＢ．the standards of training certificationＣ．the standards of trainingＤ．the standards of watch-keeping75.One especially important feature of the STCW Convention is _____.Ａ．the adoption of the policy “ more favorable treatment”Ｂ．“ no more favorable treatment” to Non-parties of the conventionＣ．the adoption of the minimum standardsＤ．the adoption of the obligatory standards76.One reason why the Convention has received such wide acceptance is _____.Ａ．that it is only the minimum standardsＢ．that it is the obligatory standardsＣ．that it is established by IMOＤ．difficulties could arise for ships entitled to fly the flag of a Non-Party State三、中译英（共2题，请将答案写在答题纸上）77. 航行期间，主机1号气缸发出敲击声，经确认敲击声来自气缸内部。

Unfortunately this is not the case as evidenced by the many marine accidents around the world-hence the need for additional control.The authority for exercising PSC is the national law based on relevant conventions. It is therefore necessary for a port State to be Party to those conventions and to have promulgated the necessary legislation before exercising PSC. In accordance with the provisions of the applicable conventions,Parties may conduct inspections of foreign ships in their ports Port State Control Officers(PSCOs).B89.The purpose of PSC is_________1) to check and inspect foreign ships2) to verify the condition of a ship in compliance with requirements of international conventions;3)to make sure that the ship is manned and operated well4)to detain shipsA 1)2) B.2)3) C.1)3) D.1234C90.Who will be responsible for ensuring that a ship maintains a standard at least equivalent to that specified in international conventions?A.PSCOsB.Ship ownersC.Flag statesD.Port statesA91.Before exercising PSC,a port state should ____________A.become a contracting Party and promulgate regulations for implementing PSCrm ship ownersC.establish proceduresrm shipping companiesC92. PSC inspection is implemented by_________through________A. flag states/PSCOsB.flag states/ship ownersC.port states/PSCOsD.port states/ship owners第二组Almost all failures in the fuel oil system,including the compression being to low,result in the crankshaft rotating more slowly if there is a failure at one or more cylinders simultaneously. If only one or two cylinders fail, and the engine is not fully loaded, the crankshaft rev/min does not decrease, the reason being that the governor ensures that the remaining cylinders are loaded to a correspondingly greater extent. If the engine is already fully loaded, the cylinders that are working normally become overloaded causing a smoking exhaust and higher exhaust temperatures etc. The load must always be reduced until the failure has been located and rectified. The reasons for a cylinder suddenly working at reduced load, or failing completely, may be :1. a defective or blocked fuel injection valve.2. the fuel oil pump piston seizing in the barrel. This failure can be ascertained by trying to move the pump‟s toothed rack.Defective fuel pumps must be changed.3. the compression being to low because of sticking , worn or broken piston rings.4. leaking inlet or exhaust valves5. no clearance in the valve operation gear.The reasons for the crankshaft rotating more slowly, or stopping completely,can also be:1. the fuel oil filter being blocked. This failure is identified by decreasing oil pressure after the fuel oil filter.2. valve sticking in the open position3. leaking fuel oil pipes or joints.4. water in the fuel oil5. the regulating mechanism being jammed6. the governor not funcitoning correctly.7. the electrical shutdown valve(the monitoring system)being activated.A93.This passage is mainly about___________A.the failure of reduced rpm.B.the failure of the governorC.how to ensure the constant rotational speedD.the reasons for the fuel system to shut downC94.If one or two cylinders fail in fuel oil system the crankshaft rev/min ___________.1)will invaviably decrease 2)does not decrease 3)will decrease under certain circumstancesA.1B.2C.3D.None of 1 2 3is trueD95. Which of the following is NOT mentioned as the reason for a cylinder suddenly working at reduced load?A.fuel valve failureB.failure of fuel pump discharge valvesC.too large gaps of piston ringsD.the fuel oil filter being blocked completelyA96.Which of the following is NOT mentioned as the reason for the crankshaft rotating more slowly or stopping?A.changing from heavy oil to light diesel oilB.connections leakingC.there being too much waterD.malfunction of the governor。

It is essential therefore that the bridge is informed of the location and extent of the fire.A small fire might reasonably be immediately tackled by the finder but attempts should be made whilst fighting the fire to attract attention. Shouting ‘Fire’, banging on bulkheads, deliberately setting off equipment alarms in the vicinity, all are possible means of attracting attention. Anyonefinding a fire must decide whether to fight it immediately or whether to leave it and inform others first. The more people who know of a fire the greater the efforts that can be brought to bear upon it.If in doubt—inform!Ships are built to contain fires in the space where they begin.Fire resisting bulkheads and decks are positioned at appropriate distances in order to limit the spread of fire, and it remains for fire fighting personnel to ensure that these barriers are secure whilst attempting to fight the fire.All doors and openings should be closed, all ventilation and exhaust fans stopped, and flammable material isolated from the space. It should be remembered that a fire exists in three dimensions and therefore has six sides, so it must be contained on six sides.69.According to the passage, once a large fire detected, _____should be informed immediately.A. chief engineerB. bridgeC. masterD. deck officer70.All of the following methods that may possibly be used to give alarms to others in case of a fireare mentioned in the passage except ____.A. shoutingB. banging on bulkheadsC. setting off equipment alarmsD. phoning71.Fire resisting bulkheads and decks provide barriers to______.A. control the spread of fireB. form a room for fire fighting personnelC. secure fire fighting personnelD. isolates fire fighting personnel72.Which one is NOT right for fire fighting?A. doors and openings to be closedB. exhausts fans to be stoppedC. fire to be controlled best in one directionD. flammable material to be isolated第二组：The introduction of invasive marine species into new environments by ships’ ballast water attached to ships’ hulls and via other vectors has been identified by the GEF as one of the four greatest threats to the world’s oceans. The other three are land-based sources of marine pollution, over exploitation of living marine resources and physical alteration/destruction of marine habitat.The I nternational Convention for the Control and Management of Ships’ Ballast Water and Sediments was adopted at an IMO Diplomatic Conference held 9-13 February 2004.

To reduce the risk of scavenge box fire, remove any oil sludge and carbon deposits in the scavenge air box and receiver in connection with the inspection.The port inspection should be carried out at the first stop after a long voyage, e.g. by anchoring if possible ,to obtain the most reliable result with regard to the effectiveness and sufficiency of the cylinder lubrication and the combustion cycle(complete or incomplete).A misleading result may be obtained if the port inspection is carried out after arrival at harbor, since manoeuvring to the quay and low –load running , e.g. river or canal passage, requires increased cylinder oil dosage , I .e. the cylinders are excessively lubricated .Further ,during low load ,the combustion cycle might not be effective and complete as expected, due to the actual fuel oil qualities and service (running ) condition of the fuel injection equipment. It is highly recommended to take this information into consideration.89、The components of an engine involved in normal scavenge port inspection comprise_______.①the piston ②piston rings ③the lower part of the cylinder liner ④the fuel injectorA. ①②B. ①②③④C. ②③D. ①②③90、If the scavenge box had too much oil sludge and carbon deposits ,what would occur?A. excessive cylinder oil consumptionB. the scavenge box fireC. the crankcase explosionD. excessive wear of the cylinder liner91、In order to obtain the most reliable result with regard to the effectiveness and sufficiency of the cylinder lubrication and the combustion cycle, when should the scavenge port inspection be carried out?_______A. at the first stop after a long voyage , e.g. by anchoring if possibleB. at the first stop after arrival at harborC. at the first stop after low load runningD. at the first stop after passing river or canal passage92、Under what condition that the scavenge port inspection can gain a misleading result?①after passed through Panama Canal ②after got alongside shanghai quay③after arrival shanghai roadstead(外锚地)A. ②③B. ①②C. ①②③D. ①第二组Current regulations with respect to the discharge of oily water set limits of concentration 15parts per million. 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 provided 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 fluoresces 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 to a slop tank.93、The passage is mainly about_______.A. oily water separatorB. current regulations related to oil pollutionC. oil in water monitorD. the principle of ultra –violet fluorescence94、A monitor can obtain all of the following functions except_______.A. measuring oil content valuesB. providing continuous recordsC. lowering the oil content below 15 ppmD. providing an alarm unit warning of levels of discharge in excess of 15 ppm95、From the passage ,we can learn that the ultra-violet fluorescence is a kind of _______.A. oil sampleB. lightC. photoelectric cellD. alarm unit96、A sample is drawn off from _______ and passes through a sample cell.A. bilge waterB. discharge of oil separatorC. slop tankD. discharge of oily water separator。

The collision resulted in serious damage to both vessels and spillage of 2,700 tonnes of fuel oil from the tanker.The cause of the sudden steering failure could not be established. Small passing distance (0.5 miles) between the two vessels precluded effective avoidance action being taken on both vessels. Both vessels unnecessarily restricted their passing distance by choosing the deepwater route although their relatively shallow draft permitted them to use the recommended directions of traffic flow outside the deepwater route.Vessels should avoid using deepwater routes when their draft permits them to use a traffic separation scheme. OOW should remain at heightened alert when passing another vessel at close range and should be vigilant(警惕) for equipment failure and unexpected response from own or other vessel including interaction between vessels passing each other at close distances.69．What happened in the story?A．An oil tanker grounded and spilled a large quantity of oilB．A bulk carrier collided with a sunken rock and spilled some fuel oilC．An oil tanker collided with a bulk carrier and spilled some fuel oilD．A bulk carrier collided with an oil tanker and spilled some fuel oil70．Which of the following statements is true?A．Improper maintenance led to the steering system failureB．Both vessels took effective avoidance actionC．There was not sufficient depth of water in the channelD．Both vessels chose the deepwater route71．Which of the following statements is NOT true?A．Vessels shall never use deepwater routesB．OOW shall always keep a sharp lookoutC．OOW shall be watchful for the equipment failureD．OOW shall be careful at the response from other vessel72．Which of the following may be the cause of the accident?A．Sudden steering failureB．Restricted passing distancesC．Both A and BD．Neither A nor B第二组：Crewmembers and other personnel onboard must familiarize themselves with the Muster list and Emergency Instructions posted up in the crew’s quarters and other conspicuous(显著的) places.The Muster list specifies details of the general emergency alarm signal and also action to be taken by crew and passengers when this alarm is sounded; specifies how the order to abandon ship shall be given; shows the duties assigned to the different members of the crew in connection with the closing of various doors and mechanisms, the equipping of the lifeboats and buoyant apparatus, the general preparation of any other boats, buoyant apparatus, inflatable life rafts and all other matters, and the extinction of fire; specifies which officers are assigned to ensure that life-saving and fire-fighting appliances are maintained in good conditions and are ready for immediate use; specifies definite signals for calling all members of the crew to their boat and fire stations and shall give full particulars of these signals.73．Which function of the followings is not mentioned about Muster list in the passage?A．How to order to abandon shipB．How to assemble the crew and passengersC．The apparatuses used to release various alarmsD．The actions of a crewmember onboard when in emergencies74．The phase “familiarize themselves with” in the first paragraph means ______.A．Be familiar with B．Familiarity withC．Get in touch with D．Used to75．The word “extinction” in the second paragraph means ______.A．Ignition B．Existing C．Extinguishing D．Breaking out76．Which one of the followings is false?A．Muster list shows officers’ duties onlyB．Muster list is posted up in the crew’s quarters and other conspicuous placesC．Muster list specifies which officers are in charge of the maintenance of lifesaving andfirefighting appliancesD．All of the above三．中译英（共5题，请将答案写在答题纸上）77．(航海日志) 航经海盗多发区域，夜间安排船员巡逻。

This is achieved by the superior combustion performance with the common-rail fuel injection.This system maintains the fuel injection pressure at the optimum level right across the engine speed range, ensuring optimum combustion under all operating conditions. In addition, a selective shut-off of single injectors at very low speeds and an optimized exhaust valve timing help to keep smoke emissions below the visible limit.Sulzer RT-flex engines also have the advantage of steady running at lower speeds than engines with mechanically-controlled injection. They can run very steadily, andwithout smoking, at 10-12% of nominal speed, which for the RT-flex 60C is about 10-14rpm. This is made possible by the precise control of injection, together with the higher injection pressures achieved at low speed, and the sequential shut-off injectors.75.According to above massage, the advantage of common-rail injection is______.A. smokeless operationB. shockless operationC. noiseless operationD. no vibration operation76.According to above massage, RT-flex engine can optimize______.① fuelinjection pressure ② combustion ③ exhaust valve timingA.①②B. ①②③C..③D. ②77.The key feature of the Sulzer RT-flex system is that it gives complete freedom inthe _____ and operation of fuel injection and exhaust valve actuation.A. meteringB. timingC. controlD. using78.The RT-flex engine can run at very low speed, this is made possible byfollowing things except _______.A. the precise control of injectionB. the higher injection pressuresC. the optimized exhaust valve timingD. the sequential shut-off injectors4三、中译英（共2题，请将答案写在答题纸上）79、（轮机日志）上午10时30分，由于不明原因运行中NO.1发电机跳闸，导致全船失电, NO.2发电机自动起动恢复正常供电。
