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. After piston overhaul, the running-in process should be carried out_____.A. periodically at steady loadB. occasionally at various loadC. continually at constant loadD. continually at various load4. 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.

Visual signals can be sent by using flags or an Aldis lamp. An Aldis lamp is an electric lamp used for flashing messages in Morse code. The traditional method of signaling from one ship to another is by using flags. There are different colored flags for each letter of the alphabet. There are also pennant-shaped flags for numbers, and a long pennant, known as an answering or code pennant. Three other flags, which are burgee-shaped, are known as substitutes. These show that the flat or pennant is being repeated. Besides standing for a letter of the alphabet, each flag, when hoisted along, has another meaning. For example, the 'W' flag also means: 'I require medical assistance'. Flags can also be hoisted in combinations of two, three or four. Siren, whistle, bell or other sound signals can be used in fog and similar circumstances when visual signals can not be seen.(1)An Aldis lamp is used for ______.A.sending flag signalsB.sending sound signalsC.transmitting Morse codeD.flashing flags(2)Burgee-shaped flags are used as substitutes to show ______.A.'I requiring medical assistance'B.'repeating'C.'answering'D.'code' pennant(3)Communications over relatively short distances may be made by ______.A.Morse CodeB.Either visual or sound signalsC.sound signalsD.visual signals(4)______ are used in fog and similar circumstances when visual signals can not be seen.A.SubstitutesB.The ship's siren, whistle or bellC.Visual signalsD.Pennant-shaped flagsThe official original data (S57 data) of the electronic nautical chart is usually supplied on CD-ROM or,in case of updates, via digital telephone or satellite communication system. This original data is also called electronic nautical chart (ENC).The chat database is organized in cells that cover the entire earth's surface without overlapping. The cells store all nautical chat objects as well as objects created only during the operation of the system, such as waypoints and leg lines, notes, positions of own ship and of other vessels, etc.The data in the System Electronic Nautical Chart (SENC) is generated from the original data of the ENC. The Enc has to be kept unaltered in order to be able to reconstruct the SENC data if this is unintentionally damaged or destroyed. In SENC, the chart data is stored in a proprietary file format designed by the ECDIS manufacturer for speed and reliability.The S57 data represents a specific kind of attributed vector data. The kind of data (object description with geometry and geographical position) requires an efficient kind of storage.
