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.

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 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。

First, it is fed through a heater and next through a centrifuge for purification. It may then pass through a cooler, before being discharged to the steam-heated heavy oil service tanks. Two of these are usually fitted and they are used alternately. One tank is in use, while the other is being filled. These tanks are heated to a moderate temperature and self-closing drain valves are fitted to remove any water or sludge which may settle out. The oil is drawn from the service tank in use by pumps and discharged at low pressure to the fuel oil heater. These pumps should be in duplicate. A relief valve on the pumps will return excess pressure to the system. A viscosity regulator is fitted at the heater discharge, through which the oil will pass. This automatically controls the temperature of the oil fuel leaving the heater to maintain its viscosity within close limits. A by-pass must be fitted to the viscosity regulator. The oil is then discharged through a fine strainer to the main engine fuel pump suctions. A pressure control valve is fitted in thesystem and excess oil returned either to the heavy oil service tanks or to a balancing tank.A diesel fuel tank is included in the system with its discharge to the primary pump suctionsthrough a change-over valve. By operating this valve the engine may be operated on diesel oil.Change-over should be very gradual to allow temperatures in the system to stabilize. During this period, the excess oil will return either to the heavy oil service tanks or a balancing tank. After it has been pumped from the DO tanks, where it is stored, the diesel oil passes through a centrifuge for purification before entering the diesel oil tank.75.The word “these” in line 4 probably means ______.A. HO tanksB. a heater and a centrifugeC. a heater and a coolerD. heavy oil service tanks76.How is change over from heavy oil to diesel oil carried out?A. Step by stepB. Hand over handC. Step for stepD. Quickly77.Where are self-closing drain valves fitted?A. HO tanksB. Heavy oil service tanksC. Balancing tankD. Centrifuge78.Which of the following statements is true according to this passage?A. Two heavy oil service tanks are used meanwhile.B.“Heater” mentioned in this passage is only used to heat heavy oil.C. Two pumps are fitted, which draw oil from the service tank in use.D. Diesel oil passes to the primary pump, and then through a change-over valve.三、中译英（共2题，请将答案写在答题纸上）79.所有费用由船东支付。

immediately ensure that corrective action is taken and shall in due course notify the Administration.If such corrective action is not taken, the Certificate shall be withdrawn and the Administration shall be notified immediately; and if the ship is in a port of another Party, the ropriate authorities of the port State shall also be notified immediately.When an officer of the Administration, a nominated surveyor or a recognized organization has notified the ropriate authorities of the port State, the Government of the port State concerned shall give suchofficer, surveyor or organization any necessary assistance to carry out their obligations under this regulation.When licable, the Government of the port State concerned shall take such steps as will ensure that the ship shall not sail until it can proceed to sea or leave the port for the purpose of proceeding to the nearest ropriate repair yard available without presenting an unreasonable threat of harm to the marine environment.Whenever an accident occurs to a ship or a defect is discovered which substantially affects the integrity of the ship or the efficiency or pleteness of its equipment covered by this Anne_ the master or owner of the ship shall report at the earliest opportunity to the Administration, the recognized organization or the nominated surveyor responsible for issuing the relevant Certificate,

the shipB.the AdministrationC.the Administration, the recognized organization or the nominated surveyor responsible forissuing the relevant CertificateD.the ropriate authorities of the port State第二组Under normal operation, some lubrication oil mist may be discharged from the air pressor to the air start system.This oil may be from e_cess pressor cylinder lubrication, fromfaulty oilscraper rings, or may even be suspended oil vapor contaminating the engine room atmosphere anddrawn in at the pressor suction.Oil discharge is kept to a minimum by draining the after cooler,air receiver and starting system.If small quantities of lubrication oil do get passed into the starting air system, they will deposit as thin moist film over internal pipe surfaces but are not readily bustible.If a cylinder non-return valve leak while the engine is in operation, some hot gas, possibly with unburned fuel and cylinder lubrication oil, may be blown through the valve to the adjacent air manifold.With further heating from the leaky valve, this, together with the already deposited oil film,will carbonize and form incandescent carbon.If starting air is lied to the system while still hot, the high pressure air ing into contact with the burning carbon may cause ane_plosion.Such an e_plosion will cause a flame to pass back through the air start pipe system, evaporating the depositedoil film and igniting it in the presence of air.Very high velocities and shockwaves are generated which may rupture pipes and fittings.Alternatively, if e_cessive oil has entered the air start system, a mi_ture of air and oil droplets maybe discharged through the open cylinder non-return valve during starting.This spray may ignite due to high temperatures in the cylinder, causing a flame through the still open valve to the air manifold.To prevent an e_plosion, air start valves must be correctly maintained and lubricated to ensure correct timing and free movement with positive closing.Oil in the system must be kept to a minimum, pipe lines must be drained and cleaned internally when necessary and oil discharge from air pressors must be kept to a minimum by good maintenance.87.The passage is mainly about .A.crankcase e_plosionB.scavenge bo_ fireC.starting air pipeD.the danger of e_plosion in the starting air system88.According to this passage, if the cylinder non-return valve were not leaky, .A.an e_plosion would not be causedB.there still would be a danger of e_plosionC.oil would not deposit in the air pipeD.pipe lines would not have to be drained89.Which of the follog is NOT mentioned in this passage?A.There may be oil vapor in the engine room。

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。

As the circuit breaker must be able to withstand closing onto a fault conditions without sustaining damage, it is of heavy construction. Fitted with an over current release mid overloads with time lags, a circuit breaker can be used as follows: to control the output of a generator; as a direct on line starter and to control outgoing feeder circuits.On modern switchboards, "draw out" circuit breakers may be fitted. In the open position the whole circuit breaker can be wound clear of the bus bars, thus full inspection and maintenance can be achieved without the necessity of de-energizing the bus bars.The "plug in" contacts joining the circuit breaker to the bus bars are not capable of taking the breaking load and it is essential that the circuit breaker is in the open position before any attempt is made to withdraw it. A mechanical interlock is fitted arranged to trip the circuit breaker before the winding handle can be inserted.The breaker also has a mid position. In this position the control circuits are still connected with the bus bar connection isolated. The electrical operation of the breaker can then be tested. Circuit breakers are normally fitted with under voltage protection and tripping is accomplished by shorting, which releases the latching in mechanism. The no-volt coil may also be open circuited by a reverse power relay and an overload trip fitted with a time delay.83. A circuit breaker can be used as follows except .A. to control outgoing feeder circuitsB. to act as a direct on line starterC. to take the breaking load on lineD. to control the output of a generator84. A "draw out" circuit breaker refers to a circuit breaker .A. which can be made clear of the bus bars by using a winding handleB. which can be made clear of the bus bars by plugging in contactsC. whose test can be carried out with the control circuits still connectedD. whose test can be carried out with the bus bar connection isolated85. A mechanical interlock is fitted .A. to take the breaking load when the circuit breaker is being withdrawnB. to put the circuit breaker, before being withdrawn, in the open positionC. to put the circuit breaker, before being withdrawn, in the mid positionD. to take the breaking load when the contacts join the circuit breaker to the bus bars86. According to this passage, the electrical operation of this kind of circuit breaker can be tested when __ .①the Circuit breaker at mid position ②the bus bar connection is isolated③the control circuits are linkedA. ①B. ②C. ②③D. ①②③第二组：Ship recycling contributes to sustainable development and is the environmentally friendly wayof disposing of ships with virtually every part of the hull, machinery, equipment, fittings and even furniture being re-used. However, while the principle of ship recycling is a sound one, the reported status of working practices and environmental standards in recycling facilities often leaves much to be desired. Such growing concerns about environmental safety, health and welfare matters in the ship recycling industry have resulted in a growing belief that an international instrument to regulate the ship recycling process is urgently needed.Having become aware of the need to reduce the environmental, occupational health and safety risks related to ship recycling, as well as the need to secure the smooth withdrawal of ships that have reached the end of their operating lives, the International Maritime Organization (IMO) has taken action to develop a realistic and effective solution to the problem of ship recycling, which will take into account the particular characteristics of international maritime transport and the economic realities.87. Which statement of the following is true?A. Ship recycling is sustainable.B. Ship recycling is very friendly to our environment.C. Ship recycling is the best way to dispose the machinery, equipment, fittings and even furniture on board.D. Ship recycling brings many problems concerning environmental safety, health and occupational safety.88. Which information is not given in the text?A. Ship recycling contributes to sustainable development.B. The IMO believes that making all international instrument to regulate the ship recycling process is urgently in need.C. An international convention on ship recycling has been adopted.D. The IMO has taken action to develop an effective solution to the problem of ship recycling. 89. What is the best explanation to the underline phrase "to secure the smooth withdrawal of ships" ? A. To withdraw a ship and make it in a safe condition. B. To secure the life of a ship and recycle it. C. To break a wreck.D. To finish the service of a ship and break it without other problems. 90. What is the main problem lied in the ship recycling industry? A. It lies in the sustainable development.B. It is about how to recycle the ship as they can as possible.C. It is a big problem concerning environment, safety and health.D. The big problem is that ship-recycling will violate the regulations made by IMO.第三组：Via the crankcase connection unit, the crankcase atmosphere is supplied to a separator in the base plate, where large particles are separated off with the aid of the centrifugal force. The oil separated off in the crankcase connection unit and in the separator is directly ducted off, via the oil drain ducts, to the air draft pump in the base plate and then out of the unit, so that it is not supplied to the opacity measuring track at all.From the separator, the sampled crankcase atmosphere is fed to the opacity measuring track in the measuring unit. In order to avoid soiling of the infrared filters by the crankcase atmosphere, a certain amount of fresh air is continuously drawn in from the vicinity of the measuring unit via one air filter in each of the two so-called scavenging air chambers. This fresh air prevents the crankcase atmosphere from entering into contact with the infrared filters. After passing the optical measuring track, the crankcase atmosphere is fed to the air draft pump. The air leaving the air draft pump contains the crankcase atmosphere and leak oil from the separator and the crankcase connection unit, and is fed to the bilge or the leak oil channel of the engine.The optical measuring track includes an infrared light emitting diode generating a certain lighting intensity at the photodiode sensitive to infrared light. The photodiode convert the lighting intensity into an electrical signal which is fed to the electronic evaluation unit. If the crankcase atmospherecontains oil mist, part of the infrared light is absorbed in the measuring track. As a result, the electrical signal is weakened. A higher opacity of the crankcase atmosphere will produce a lower electrical signal. This electrical signal is monitored in the electronic evaluation unit for falling short of aminimum threshold value. This means for the opacity of the crankcase atmosphere that it is monitoredfor exceeding a maximum threshold value.91. According to this passage, the oil separated off in the crankcase connection unit and in the separator is directly ducted off and finally fed to___.A. the opacity measuring trackB. the bilge or the leak oil channel of the engineC. the scavenging air chambersD. the collection chamber92. If the infrared filters were soiled by the crankcase atmosphere, what would take place? A. the oil mist detector would produce an oil mist alarm B. the air draft pump would increase its outputC. the built-in heating unit would put into operationD. the sintered bronze air filters would by large particles93. Which generate the infrared light in the optical measuring track? A. the sintered bronze air filters B. the infrared filters C. the emitting diode D. the photodiode94. When the oil mist in the crankcase atmosphere exceeded a maximum threshold value, an electrical signal produced by the photodiode would .A. increase to a minimum threshold valueB. decrease to a minimum threshold valueC. remain constant without variationD. absorb the most intensive infrared light。
