10、 or stroke. “Stroke” refers to piston movement; a stroke occurs when the piston moves from one limiting position to the other. The upper limit of piston movement is called TDC (top dead center). The lower limit of piston movement is called BDC (bottom dead center). A stroke is piston movement from T

11、DC to BDC or from BDC to TDC. In other words, the piston completes a stroke each time it changes its direction of motion.Where the entire cycle of events in the cylinder requires four strokes (or two crankshaft revolutions), the engines is called a four-stroke-cycle engine, or a four-cycle engine. T

12、he four piston strokes are intake, compression, power, and exhaust.1.What do we see from the paragraphs? ( )A. What is stroke? B. What is engine? C. What is cylinder?2. Which one Statement is true according the above first paragraph? ( ) A. A four-stroke-cycle engine means that four strokes is requi

13、red when it finish the whole cycle. B. A stroke is not piston movement from TDC to BDC, but from BDC to TDC.C. The lower limit of piston movement is called TDC (top dead center).3. What is BDC in the term of automobile industry? ( ) A. Bottom dead center. B. Top dead center. C. Neither of A and B.4.

14、 Which one Statement is TRUE according the last paragraph? ( ) A. The four strokes occur in two crankshaft revolutions. B. The four strokes occur in four crankshaft revolutions. C. The four strokes occur in one crankshaft revolutions.5. Which one Statement is TURE according the article? ( ) A. The f

15、our piston strokes are intake, compression, power, and exhaust. B. The four piston strokes are intake, compression, power, and inhauls. C. The four piston strokes are intake, combining, power, and exhaust.Part 2Power stroke: As the piston reaches TDC on the compression stroke, an electric spark is p

16、roduced at the spark plug. The ignition system delivers a high-voltage surge of electricity to the spark plug to produce the spark. The spark ignites, or sets fire to, the air-fuel mixture. It now beings to burn very rapidly, and the cylinder pressure increases to as much as 3-5 Mpa or even more. Th

17、is terrific push against the piston forces it downward, and a power impulse is transmitted through the connecting rod to the crankpin on the crankshaft. The crankshaft is rotated as the piston is pushed down by the pressure above it.6. Which topic is fit with the paragraph? ( ) A. Power stroke B. Co

18、mpression stroke. C. Exhaust stroke. 7. Which one Statement is TURE according the article? ( ) A. The terrific push against the piston forces it downward. B. The slight push against the piston forces it downward. C. This little push against the piston forces it downward.8. Which word or phrase can c

19、hange the word “ignites”? ( ) A. sets fire to B. shoots at C. charges 9. Which one Statement is TURE according the article? ( ) A. The ignition system delivers a high-voltage surge of electricity to the spark plug to begin the spark. B. The ignition system delivers a low-voltage surge of electricity

20、 to the spark plug to defend the spark. C. The ignition system delivers a constant-voltage surge of electricity to the spark plug to produce the spark.10. When the air-fuel mixture beings to burn very rapidly, how much does the cylinder pressure increase to? ( )A. As much as 3-5 Mpa or even more.B.

21、As much as 3-5 bar or even more.C. About 3-5 Kpa. Part 3 We all know that diesel engines, in principle, work in the same way as gasoline engines do. Both kinds of engines are internal combustion engines, but each of them has its characteristic features. Now let us compare the diesel engine with the

22、gasoline engine. Firstly, the explosive mixture of the gasoline engine is provided by a carburetor, but in the case of the diesel engine the supply is affected by an injection or “jerk” pump which forces a “shot” of fuel into each cylinder in turn according to the correct firing sequence. Secondly,

23、the fundamental difference between gasoline and diesel engines is that in the gasoline engine the source of the heat for igniting the charge, namely, an electric spark, is generated outside the engine, and is taken, as it were, into the waiting charge at the required instant. In the diesel engine th

24、e source of heat for igniting the charge is created within the engine by compressing pure air to a degree that will initiate combustion and then injecting the fuel at the right time in relation to the movement of the crankshaft.11. What do we see from the first paragraph? ( )A. Diesel engines work i

25、n the same mean as gasoline engines do.B. Diesel engines dont work in the same way as gasoline engines do.C. Either of A and B. 12. Which one Statement is true in the article? ( )A. the explosive mixture of the gasoline engine is provided by a carburetor. B. the fuel supply of the diesel engine is a

26、ffected by an injection or “jerk” pump. C. both of A and B13. What is the fundamental difference between gasoline and diesel engines? ( ) A. In the gasoline engine, an electric spark plug is required in a cylinder. B. In the diesel engine, an electric spark plug is required in a cylinder. C. Both of

27、 A and B. 14. Which one Statement is true in the term of diesel engines in the article? ( ) A. the diesel engine the supply is affected by an injection.B. the diesel engine the supply is affected by or a “jerk” pumpC. Both A and B.15. Which topic is fit with the article? ( ) A. Diesel engine operati

28、ng features. B. Gasoline engine operating features. C. Jerk pump operating features. Part 4 Both classes of engines are of very similar construction. But as the higher pressure is called upon in cylinders, it has to be of more substantial construction, and is thus heavier. In general, the diesel eng

29、ine may weigh about 9.25 kilograms per kilowatt. The most important advantage of the gasoline engine is its lower weight per kilowatt. The gasoline engine for automobiles may weigh about 6.17 kilograms per kilowatt, and gasoline engines for airplanes may weigh as 0.77 kilograms per kilowatt. This ad

30、vantage prevents the diesel engine form replacing the gasoline engine in some automobiles and airplanes. In addition, the engine runs cooler than the gasoline engine. This advantage is especially obvious at lower speeds. Diesel oil is not only cheaper than gasoline, but also safer to store.16. Which

31、 one Statement is true in the term of engines in the article? ( ) A. Both classes of engines are of very similar construction. B. Both classes of engines are of a little similar construction. C. Both classes of engines are NOT of similar construction.17. How many kilograms per kilowatt may the diesel engine weigh generally? ( ) A. about 9.25B. about 0.77C. about 6.1718. What is the most important advantage of the gasoline engine? ( )A. its lower weight per kilowatt. B. its higher weight per kilowatt. C. neither of A and B19. What advantage is especially o
