The burning of the oil in the cylinders of the diesel engine or gasoline

44、 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. h

45、at do people use to drive a modern ship? A. the wind B. the sail C. the oars D. the machines 70. Which of the following does not directly burn oil? A. A gasoline engine B. A diesel engine C. An electrical motor D. None of them 71. What does a generator provide? A. driving power B. a great deal of he

46、at C. friction D. electricity 72. Whats the function of the lube oil? A. to take away the heat B. to reduce friction C. to remove the detritus 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 al

47、ternator. 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 and current and is expressed as the

48、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 the product 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 is therefore the product of current,
