If only one or two cylinders fail, and the engine is not f ully loaded, the crankshaf t rev/min does not decrease, the reason being that the governor ensures that the remaining cylinders are loaded to a correspondingly great er extent. If the engine is already f ully loaded, the cylinders that are working normally become overloaded causing a smoking exhaust and higher exhaust temperatures etc. The load must always be reduced until the f ailure has been located and recti f ied. The reasons f or a cylinder suddenly working at reduced load, or failing completely, may be :1. a def ective or blocked f uel injection valve.2.the f uel oi l pump piston seizing in the barrel. This f ailure can be ascertained by trying to move the pump‟s toothed rack.Defective f uel pumps must be changed.3.the compression being to low because of sticking , worn or broken piston rings.4 leaking inlet or exhaust valves5. no clearance in the valve operation gear.The reasons f or the crankshaf t rotating more slowly, or stopping completely,can also be:1. the f uel oil f ilter being blocked. This f ailure is identif ied by decreasing oil pressure af t er the f uel oil f ilter.2.valve sticking in the open position3.leaking f uel oil pipes or joints.4.water in the f uel oil5.the regulating mechanism being jammed6.the governor not f uncitoning correctly.7the electrical shutdown valve(the monitoring system)being activated.93.This passage is mainly aboutA.the f ailure of reduced rpm.B.the f ailure of the governorC.how to ensure the constant rotational speedD.the reasons f or the f uel system to shut down94.If one or two cylinders fail in f uel oil system the crankshaf t rev/min .1)will invaviably decrease 2)does not decrease 3)will decrease under certain circumstancesA.1B.2C.3D.None of 1 2 3is true95. Which of the f ollowing is NOT mentioned as the reason f or a cylinder suddenly working at reduced load?A.f uel valve f ailureB.f ailure of f uel pump discharge valvesC.too large gaps of piston ringsD.the f uel oil f ilter being blocked completely96.Which of the f ollowing is NO T mentioned as the reason f or the crankshaf t rotating more slowly or stopping?A.changing f rom heavy oil to light diesel oilB.connections leakingC.there being too much waterD.malf unction of the governor 46轮机英语的答案1- 5 DBABC 6-10 BDBAB11-15 CDCBC 16-20 BCACA 21-25 CDDBA 26-30 BDABA 31-35 BDADA 36-40 BCACB 41-45 DDDBC 46-50 DABDA 51-55 BBDBA 56-60 DDDAD 61-65 BBBCC 66-70 CADDB 71-74 ACABA 76-80 DBADB 81-87 CCAC ACD 88-AB 89-92 ~~~~ 93-96~~~~。

The inspection consists of visually examining the piston, the rings and the lower part of the cylinder liner, directly through the scavenge air ports To reduce the risk of scavenge box fire, remove any oil sludge and carbon deposits in the scavenge air box and receiver in connection with the inspection.The port inspection should be carried out at the first stop after a long voyage, e.g. by anchoring if possible, to obtain the most reliable result with regard to the effectiveness and sufficiency of the cylinder lubrication and the combustion cycle (complete or incomplete)A misleading result may be obtained if the port inspection is carried out after arrival at harbor, since manoeuvring to the quay and low-load running, e.g. river or canal passage, requires increased cylinder oil dosage, i.e. the cylinders are excessively lubricated, Further, during low load, the combustion ccle might not be as effective and complete as expected, due to the actual fuel oil qualities and service (running) condition of the fuel injection equipment. It is highly recommended to take this information into consideration.89.

A monitor is required to measure these values and provide both continuous records and an alarm where the permitted level is exceeded.The principle used is that of ultra-violet fluorescence. This is the emission of light by a molecule that has absorbed light. During the short interval between absorption and emission, energy is lost and light of a longer wavelength is emitted. Oil fluoresces more readily than water and this provides the means for its detection.A sample is drawn off from the overboard discharge and passes through a sample cell. An ultra-violet light is directed at the sample and the fluorescence is monitored by a photoelectric cell Where an excessive level of contamination is detected an alarm is sounded and diverting valves are operated. The discharging liquid is then passed to a slop tank.93. The passage is mainly about ________.A. oily water separatorB. current regulations related to oil pollutionC. oil in water monitorD. the principle of ultra-violet fluorescence94. A monitor can obtain all of the following functions except _______.A. measuring oil content valuesB. providing continuous recordsC. lowering the oil content below 15 ppmD. providing an alarm unit warning of levels of discharge in excess of 15 ppm95.

Both use a basically similar arrangement of an automatic pump supplying the liquid to a tank which is pressurized by compressed air. The compressed air provides the head or pressure to supply the water when required．The pump is started automatically by a pressure switch which operates as the water level falls to a predetermined level．The fresh water system has，in addition，a calorifier of heater which is heated，usually with steam．Fresh water supplied for drinking and culinary purposes must meet purity standards specified by the Department of Transport．Water produced from most evaporator/distillers will not meet these standards and must be treated to ensure it is biologically pure and neutral or slightly alkaline．A treatment plant suitable for a general cargo ship is shown in Figure 6.21．The water is sterilizedby an excess dose of chlorine provided as hypochlorite tablets．It is then de-chlorinated in a bed of activated carbon to remove the excess chlorine．Any color, taste and odor which was present in the water will also be removed by the carbon．Excess chlorine is originally applied to insure that complete sterilization occurs.(1)What's the function of the Domestic water system?

CoCoS consists of four modules that can be used individually or together. The modules can help in fault finding, work planning, managing ship's stock and handling spare parts orders. An electronic version of the instruction book will also be included in the complete package.CoCoS has been developed within the MAN B＆W Diesel group and, in the programming, both MAN B＆W Diesel's main engine and auxiliary engines have been considered.The development work is being performed as an inter-company project, involving MAN B＆W Diesel in Copenhagen (MBD-K), Alpha Diesel (MBD-F),Holeby Diesel (MBD-H), MAN B＆W Diesel in Augsburg (MBD-A) and Pielstick in France. The engine diagnostics part is being developed on the basis of the experience gained with MBD-K's CAPA, MBD-A's Modis and MBD-H's HGM and will, when finished, be able to replace these products. The three other modules include areas that are new to us.(5)How many companies are mentioned in the passage to carry out the development work?

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 befrequently 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. Small package boilers will use ____C___ while being lit up.A. the usual source of oilB. fuel oilC. diesel oilD. mixture of fuel oil and diesel oil76.
