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.

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。

The burning of the oil in the cylinders of the diesel engine or gasoline engine provides the ship with driving power. The electrical motor runs on the electrical power. But the generator also consumes oil to produce this kind of power. Beside, the lube oil can reduce the friction between the moving parts of the engine and has much to do with its working condition.69.Ｗhat do people use to drive a modern ship?A. the windB. the sailC. the oarsD. the machines70.Which of the following does not directly burn oil?A. A gasoline engineB. A diesel engineC. An electrical motorD. None of them71.What does a generator provide?A. driving powerB. a great deal of heatC. frictionD.electricity72.What’s the function of the lube oil?A. to take away the heatB. to reduce frictionC. to remove thedetritus D. all of the A.B.C第二组：The field current supply in older machines comes from a lower voltage direct current generator or exciter on the same shaft as the alternator. Modern machines however are either statically excited or of the high-speed brush-less type. The exciter is required to operate to counter the effects of power factor for a given load. The power factor is a measure of the phase difference between voltage andcurrent and is expressed as the cosine of the phase angle. With a purely resistance load the voltage and the current are in phase,giving a power factor of one. The power consumed is therefore theproduct of voltage and current. Inductive or capacitive loads,combined with resistance loads, produce lagging or leading power factors which have a value less than one. The power consumed istherefore the product of current, voltage and power factor. Thealternating current generator supplying a load has a voltage drop resulting from the load. When the load has a lagging power factor this voltage drop is considerable. Therefore the exciter, in maintaining the alternator voltage, must vary with load current and also the power factor. The speed change of the prime mover must also be taken into account.73.The word “machines” in the passage refers to ______.A. the direct current generatorB. the alternating currentgeneratorC. the exciterD. the prime mover74.Which of the following statements is true according to the passage ?A. With a purely resistance load, the power factor is zero.B. Inductive loads combined with resistance loads produces leadingpower factors.C. Capacitive loads combined with resistance loads produces laggingpower factors.D. With a purely resistance load, the phase angle is zero.75.When the load has a lagging power factor this voltage drop isconsiderable. This sentence means that ______.A. with a purely resistance load, the voltage drops too muchB.there is a considerable voltage drop in the capacitive load combinedwith resistance loadC.when the load is the capacitive load combined with resistance load,the voltage drops tozeroD.when the load is the inductive load combined with resistance load,the voltage drop isfairly large76.The exciter must vary with : Ⅰ. load current. Ⅱ. the power factor.Ⅲ. speed change of the prime mover.A. onlyⅠB. only ⅡC.Ⅰand ⅡD.Ⅰ, Ⅱ and Ⅲ三．中译英77. 螺旋桨需拆卸，尾轴拉出检查修理，所有拆卸部件重新装妥。

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 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.2) 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 anemergency 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.69.

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.73.Small package boilers will use _______ while being lit up.A.the usual source of oilB.fuel oilC.diesel oilD.mixture of fuel oil and diesel oil74.After large boilers being secured, the fuel in the feeding line will be____.A.the usual source of oilB.fuel oilC.diesel oilD.mixture of fuel oil and diesel oil75.If large boilers were not lit up, _____.A.feed water to normal levelB.stop fuel supply immediately and purge the furnaceC.light the boiler againD.reset the burner76.An indication for a good combustion is ______.A.white smokeB.brown haze in the funnelC.orange flame tipD.swirl oil spray答案：CCBBCCBC三、汉译英1. 1号主空压机不能加压，进行了拆卸、清洁、检查，排气阀片发现断裂，换新、装复后进行了试验。
