(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.

章节训练篇Lesson 1 Ships and MachineryI. Translate the following phrases into Chinese:1. naval architect2. marine engineer3. longitudinal bulkhead4. transverse bulkhead5. container vessel6. roll on and roll off7. bulk carrier 8. crude carrier9. passenger ship 10. displacement11. light weight 12. deadweight13. metric ton 14. long tonII. Translate the following sentences into Chinese:1. Some overlap in responsibilities occurs between naval architects and marine engineers in areas such as propeller design, the reduction of noise and vibration in the ship’s structure, and engineering services provided to considerable areas of the ship.2. Depending on the nature of their cargo, and sometimes also the way the cargo is loaded/unloaded, ships can be divided into different categories, classes, and types, some of which are mentioned in Table 1.3.

During the suction stroke, the diesel engine admits air only, but the gasoline engine admits a combustible mixture of air and gasoline. After compression, a fine spray of fuel injected into the diesel engine cylinder is ignited by the heat in the cylinder. A gasoline engine needs spark plugs to ignite the combustible mixture in the cylinder. The compression ratio of a diesel engine is higher than that of a gasoline engine. So a diesel engine is bigger than a gasoline engine.2.Xiao Wang is a cadet of the engine department, who just graduated from ShanghaiMaritime University. How do you introduce all the engine room to him?I will introduce the engine room to him in this way: This is the engine room. It is below the first deck on board .There are many machines and equipment in it, including a main engine and a lot of auxiliary machines. This is the economizer, standing just in front of the door .Down the staircase, there is a boiler. Going down some more, you will find a passage leading to the steering gear room. Moving down another flight of stairs, you will come to the level of main engine cylinder heads. Up from there, there are diesel generators. The fresh water generator is also on he same level. As the heart of a ship, the engine room should be kept in good order.3.Xiao Zhang is a three-year student majoring in marine engineering from ShanghaiMaritime University.How do you introduces the equipment and machinery in the engine room to him?I will introduce the equipment and machinery in the engine room in this way: There are many kinds of machines in the engine room. The main engine is the heart of the engine room. It supplies power for the vessel’s propulsion. Boilers are used for producing steam. A fresh water generator is used to produce fresh water from seawater. An air compressor is to supply compressed air. Steering gears are for the control of the ship’s course. All the machinery and equipment should be maintained in good order.4.Look at the illustration and say something about the disposal of the shafting anddiesel engine.I will say something about the disposal of the shafting and diesel engine. The main diesel engine is with a thrust shaft as an integral part. The thrust is bolted to an intermediate shaft. The intermediate shaft is supported by intermediate tunnel bearings. The sterntube bearing supports the tailshaft and part of the propeller weight. Sterntube seals are fitted at both ends of the tailshaft. The shafts, shaft bearings and probability make up the transmission system on board a vessel.5.Look at the illustration and say something about the probability of disposal ofmedium-speed and high-speed diesel engine.Medium-and high-speed diesel engines can be arranged as single-engine propulsion. But they are probably arranged as two-, even three-or four-engine propulsion. The illustration shows a kind of four-engine propulsion. These engines are connected with a reduction gear. Through the reduction gear, the propelling speed is reduced and the torque is increased. One of the advantages of this arrangement is that compact systems can be used.6.Look at the illustration and say something about structure of the main engine.This is an illustration of the structure of a main engine. The main engine consists of two parts: the moving parts and fixed parts. The moving parts include piston, crankshaft, and connecting rod. The fixed parts are bedplate, frame, cylinder, cylinder cover and main bearings. The bedplate, frame and cylinder block are held together by long tie rods. The connecting rod connects the piston with the crankshaft. The piston moves up and down in the cylinder. On the top of the cylinder, there is a cylinder cover. The exhaust valve, inlet valve and injector are installed on the cylinder cover.7.Look at the illustration and say something about stress status of the moving parts.This picture illustrates the stress status of the moving parts of an engine. The moving parts are stressed by two major forces. One is the compressive force from the gas in cylinder. The other is the inertia force of the moving parts. The resultant force of the two can be divided into Force N and Force S. Force S compresses or stretches the connecting rod. And it can be further divided into Force T and Force K. Force K exerts a bending stress on the crankshaft.8.Look at the illustration and say the type of piston head shape in diesel engine.This picture illustrates the shape of a piston head. There are four piston ring grooves in the head. The top of the piston head is concave, like a bowl. This shape is favorable for the mixing of fuel and air. It is also for the free expansion of the head after being heated. The type of this piston is probably a crosshead type.9.Look at the illustration and say the types of piston ring.This picture illustration various types of piston ring. The first one in the picture is the section of a rectangular ring. This kind of piston ring is most common for gas sealing. The second one is a diagonal cut piston ring. It is commonly used for oil distributor ring. The third one is a kind of piston ring with one inner-side chamfer.The fourth one is a twisted ring. And the fifth one is with an oval shape at the outer side. It is particularly used for the running-in period of a new piston.10.Please describe the lubricating mode of main engine.There are two different lubricating modes of main engine. One is for lubrication of the cylinders. The other is for bearing lubrication. The cylinder oil is usually provided by small pumps, known as mechanical lubricators. The oil should be supplied in small quantities. But the method of nearing lubrication is quite different. It is provided by forced feed system. It provides a sufficient supply of oil to all bearing. Lubrication of the main engine can reduce friction.11.Talk about the working principle of purifier according to the picture given.The picture shows the working principle of a purifier on board. It works on the principle of centrifugal separation. In a purifier, there are separation discs and outer periphery with a series of holes. When oil is pumped into it, the centrifugal force causes water to be forced to the outer periphery. A cylindrical interface is formed between the water and oil. The oil is forced inward and up to the clean oil outlet. By this way, a purifier can remove water from fuel oil.12.Talk about the working principle of oily water separator according to the picturegiven.The picture shows the working principle of an oily water separator. It works on the principle of gravity separation. When operated, the oil water separator is first filled with clean water. The oily water mixture is then pumped into the coarse separating compartment. Here some oil will separate and rise into the oil collection space. The remaining mixture now flows down into the fine separating compartment. More oil will separate out. The almost oil-free water passes into the central pipe and leaves the separator unit. The oil content in the water may be 100 ppm or less.13.Talk about the anti-pollution equipment on board ship.Anti-pollution equipment is necessary especially for ocean-going ships. The equipment includes the oily water separator, the incinerator and the sewage treating system. The oily water separator is used to treat the bilge water before discharging it overboard. The incinerator is used to burn oil wastes and some solid wastes on board. The biological sewage treatment plant is used to treat the sewage on board. These devices perform their duties to prevent pollution from ships to the sea. We should take great care of them. We should ensure that they all meet the requirements of the MARPOL Convention.14.Talk about the operation of the ballast system.The ballast system is used to bring the ship’s drafts into a seaworthy condition.Water can be drawn from any tank or the sea, or be discharged to any other tank or the sea. By this way, it can trim the vessel as required. Combined or separate mains for suction and discharge may be provided. We must operate the ballast system according to the international and port regulations. Water from CBTs (clean ballast tanks) or SBTs (segregated ballast tanks) can be discharged directly.Ballast water from fuel oil tanks should be discharged overboard through an oily water separator.15.Talk about the operation of the bilge water system.The operation of the bilge water system is an important routine work. It needs great care. The discharge of bilge waer must meet relevant requirements about pollution prevention. The bilge water should be treated by an oily water separator before being discharged overboard. The oil content limit should not exceed 15 ppm. The duty engineer should discharge the bilges before handing over a watch.The operation must be reported in the Oil Record Book. It should also be reported to the Chief Engineer. And the relieving engineer should check the bilge level when taking over a watch.第三章驾机联系munications with officersCommunications between the engineers and deck officers are very important.Lf the communication fail, accidents may happen.While they are keeping watch, they will communicate with each other by telephone. For example, the duty officer will inform the duty engineer when to stand by engine, when to check out telegraph and when the ship will arrive at the port.Before the engineer gives the main engine a trial on power, he should inform the officer.While testing the steering gear，the engineer will report the rudder angle to the bridge.Lf anything unexpected happens, they will notify each other as soon as possible.2.Noon reportA noon report must be written every day .Lt is a table with three columns.The first column is for daily performance data.Here we should enter some data concerning the main engine, ship and voyage.The second column is for remarks of the Chief Engineer.And the third one should be filled in with the working hours of the main and auxiliary engines.3.Take over watchTake over an engineering watch is an important procedure in watch-keeping .The relieving engineer should be in the engine room 15 minutes ahead of time.Before taking over watch，the relieving engineer should check various things.He should read the standing orders and special instructions of the Chief Engineer.He should be aware of all work being performed on machines and systems.Then he should take a tour around the engine room.He should check the level and condition of fuel tanks, lube oil tanks, water tanks and bilges.He should check all temperatures and pressures of various working systems.He should check the running conditions of the main and auxiliary engines.When every is found in good condition, the relieving is considered completed. 4.Before handing over an engineering watch, the engineer to be relieved shouldrecord all the incidents happened during his watch.He should tell the relieving engineer whether there are any special instructions, all work being performed on machinery and systems.He should tell the relieving engineer the liquid levels and conditions of various tanks being used .If the ship is in port, he should tell the relieving engineer the communication channel with the shore personnelAnd he should tell him all other things concerning the safety and environmental protection .5.Standby engine before departureWhen standing-by engine before departure ,we should do various things.We should check various systems of the main engine .We should warm up the main engine .We should prime the lube oil pump and vent the air from the system .We should start the lube oil pump and make sure that lube oil supply is in order.We should pump up the starting air reservoirs to their maximum pressure.We should check the reversing and control gear of the main engine .We should engage the turning gear and give the engine at least one complete turn.After informing the bridge ,we will give the main engine a brief trial on power ahead and astern .Finally ,we will ring ―stand-by‖ on the engine telegraph.6.Standby engine after sailing.(1)When do you begin standing by engine?(2)How do you stand by engine?After a period of sailing, a ship will arrive at a port.We should begin standing by engine before arriving.The starting air receivers must be pumped up to be read for maneuvering.Some control modes must be changed over from automatic to hand control.About one hour before engine movements, heavy oil should be changed over to diesel.The starting air system should be drained.Lf permissible, a test reversal of the engine should be carried out before arrival in congested waterways.7.Measures to be taken by duty engineer at rough seaWhen sailing at rough sea, the ship will pitch and roll violently.We should pump up the slack tanks and secure some movable things.The main engine speed may exceed the maximum allowable RPM because the propeller may be above the sea surface.The ship’s speed may be reduced because of greater resistanc e.So we should closely observe the working condition of the main engine.And we should get ready to any emergency conditions.8.Actions to be taken after ―Finished with engine’ ‖.(1)When do you begin finishing with engine?(2)How do you finish with engine?Afte r the bridge gives the order ―Finished with engine‖, we begin finishing with the engine.We should check various control levers.We should shut various valves and open various cocks.We should gradually reduce the cooling water temperature over a period of 8 hours.And we should turn the main engine through 3or 4 turns at first.Then we should turn the main engine through one turn at interval during cooling.9.Talk about the steering gear testingSteering gear is one of the key equipment on board.It is u sed to control the ship’s course.Both main and auxiliary steering gears should be tested using the emergency power supply.Alarms should also be checked for correct operation.This job should be done before departure from or arrival at a port.Lf requested by the port state control and officer, testing should also be done.While testing the steering gears, the deck officer and the engineer should work together.The rudder angle should be check and the system be tested.Any error or malfunction if found should be corrected.10.Actions to be taken in the case of the trial of main engineThe main engine should be tried to ensure its good working order.Before the trial, we should warn up the engine.We should engage the turning gear and give the engine at least one complete turn.We should open the scavenge drains.We should ask the bridge for permission to test the main engine.After getting permission from the bridge, we start the engine on air.Then we close all indicator cocks.We will give the engine a brief trial on power ahead and astern.11.Talk about engine room orders.Engine room orders are mainly standard engine orders.―Standing by engine‖ requires that engine room personnel get fully ready to manoeuvre .―Full ahead‖ means the maximum manoeuvring engine revolution for forward propulsion .―Full astern‖ means the maximum manoeuvring engine revolution for astern propulsion .And other engine orders include ―half ahead‖ ,‖half astern‖, ―slow ahead‖, ―slow astern‖ ,‖dead slow ahead‖ and ―dead slow astern‖ .―Finished with engine‖ means that moment of engine is no longer required .Engine orders are transmitted between the bridge and engine room through the telegraph .12.Talk about the telegraph in engine roomThe telegraph in the engine room is very important device.It is installed on the control console.Its movement is transmitted to the telegraph on the bridge.The bridge and the engine room use this system to communicate engine movements.It is usually used when the ship is going into or out of a port.The telegraph control lever has four ―ahead‖ and four ―astern‖ positions with the ―stop‖ position in the middle.第四章应急用语1、Describe briefly one of the main engine breakdown cases you experienced
