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

By adding the ISM Code to SOLAS it is intended to provide an international standard for the safe management of ships and for pollution prevention.The ISM Code establishes safety management objectives which are: to provide for safe practices in ship operation and a safe working environment; to establish safeguards against all identified risks; to continuously improve safety management skills of personnel, including preparing for emergencies.The Code requires a safety management system (SMS) to be established by "theCompany", which is defined as the ship-owner or any person, such as the manager orbareboat charterer, who has assumed responsibility for operating the ship. This system should be designed to ensure compliance with all mandatory regulations and that codes, guidelines and standards recommended by IMO and others are taken into account.The SMS in turn should include a number of functional requirements: a safety andenvironmental protection policy; instructions and procedures to ensure safety andenvironmental protection; defined levels of authority and lines of communication between and amongst shore and shipboard personnel; procedures for reporting accidents, etc.;procedures for responding to emergencies; procedures for internal audits and management review.The Company is then required to establish and implement a policy for achieving theseobjectives. This includes providing the necessary resources and shore-based support. Every company is expected "to designate a person or persons ashore having direct access to thehighest level of management".69.The new chapter of the SOLAS is mainly on ______.A. the watch-keeping standards for seafarersB. the certification standards forseafarersC. the ISM CodeD. thetraining standards for seafarers70.The safety management objectives of the ISM Code are ______.A. to provide for safe practices in ship operation and a safe working environmentB. to establish safeguards against all identified risksC. to continuously improve safety management skills of personnel, including preparing foremergenciesD. all the above71.The term "the Company" in the ISM Code is defined as ______.A. the ship-ownerB. any person who has assumed responsibility foroperating the shipC. either A or BD. neither A nor B72.The “person”in the phrase "to designate a person or persons ashore having direct access tothe highest level of management" refers to ______.A. the manager of the shipping companyB. the master of the shipC. the designated person on board shipD. the designated person ashore第⼆组：The electrical remote control system is commonly used in modern steering installations since it uses a small control unit as transmitter on the bridge and is simple and reliable in operation.The control box assembly is mounted on the steering gear. Movement of the bridge transmitter results in electrical imbalance and current flow to the motor in the control box.The motor drives, through a flexible coupling, a screw shaft, causing it to turn. A screw block on the shaft is moved and in turn moves the floating lever to which a control rod is attached.The control rod operates the slipper ring or swash plate of the variable delivery pump. Acut-off lever connected to the moving tiller will bring the floating lever pivot and the lever into line at right angles to the screw shaft axis. At this point the rudder angle will match the bridge lever angle and the pumping action will stop. For local manual control, the electrical control is switched off and a small hand-wheel is connected to the screw shaft. Rotation of the hand-wheel will move the floating lever and bring about rudder movement as desired.73.This passage is mainly on ______.A. the electrical remote control of main enginesB. the electrical control equipment of steering gearsC. the bridge remote control of main enginesD. the control box assembly in steering gear compartment74.The advantage of the control equipment is ______.A. that the transmitter is on the bridgeB. that local manual control can be achieved.C. that remote control cab be achieved.D. simple in construction and reliable in operation75.The function of the cut-off lever is ______.A. to provide electrical signalB. to provide feed-backC. to provide local manual controlD. to provide right rudder angle76.Another name for the “swash plate”in the variable delivery pump is ______.A. tiltable discB. gravity discC. distributing discD. catch plate三、中译英（共2题，请将答案写在答题纸上）77.填写《油类记录簿》时，⽇期、作业代码和项⽬编号，应记⼊相应的表格内，所要求的细节，应按年⽉顺序记⼊空栏。
