The automobile engine is an internal combustion engine because the fuel (gasoline) is burned inside it. The burning of gasoline inside the engine produces high pressure in the engine combustion chamber .This high pressure forces piston to move, the movement is carried by connecting rods to the engine crankshaft. The crankshaft is thus made to rotate: the rotary motion is carried through the power train to the car wheels so that they rotate and the car moves. 1. What do we see from the first paragraphs? ( ) A. The engine is source of power for a car. B. The engine can not make wheels go around. C. The engine is resource of oil. 2. Which one Statement is true according the above first paragraph? ( ) A. The automobile engine is an international combustion engine. B. The automobile engine is an external combustion engine. 第 1 页 共8页 C. The automobile engine is an inner combustion engine 3. What do we see from the second paragraphs? ( ) A. High pressure is source of power inside a engine. B. Crankshaft is rotated without any force. C. Combustion chamber is not a part of the engine. 4. Which one Statement is true according the above second paragraph? ( ) A. The movement of piston is carried by connecting rods to the engine crankshaft. B. .This lower pressure forces piston to move. C. Both of A and B are true. 5. Which one Statement is true according the last sentence in the article? ( ) A. The power train is required for a car moving. B. The rotary motion of crankshaft is enough for a car moving. oth A and B are false. C. B Part 2 The engine also needs a cooling system; the combustion of the air-fuel .The mixture in the engine c to 2700?). The cooling system takes heat away reates a very high temperature (as high as 2000? from the engine by circulating a liquid coolant (water mix with antifreeze) between the engine and a radiator .The coolant gets hot as it goes through the radiator. Thus, the coolant continually takes heat away from the engine, where it could do damage, and delivers it to the radiator .Air passing through the radiator takes heat away from the radiator. 6. What do we see from above paragraph? ( ) A. a cooling system is must for the engine . B. The engine don’t need a cooling system C. The engine might need a cooling system. 7. How much will be created the temperature of the mixture in the engine? ( ) A. As high as 2000? to 2700?. B. As high as 1300? to 2000?. C. Not higher than 2000?. 8. What is liquid coolant? ( ) A. water mix with antifreeze B. water used by the cooling system. C. Any liquid used by the cooling system. 9. What do we see from above paragraph? ( ) 第 2 页 共8页 A. The coolant gets HOT as it goes through the radiator . The coolant gets COOL as it goes through the radiator B C. Both A and B are false. 10. Which one Statement is true in the article? ( ) A. Air passing through the radiator takes heat away from the radiator. B. Air passing through the radiator gets MORE heat. C. Both A and B are false. Part 3 Power stroke: As the piston reaches TDC on the compression stroke, an electric spark is produced 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. This 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. 11. Which topic is fit with the paragraph? ( ) A. Power stroke B. Compression stroke. C. Exhaust stroke. 12. 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. 13. Which word or phrase can change the word “ignites”? ( ) A. sets fire to B. shoots at C. charges 14. 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 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. 第 3 页 共8页 15. 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. As much as 3-5 bar or even more. C. About 3-5 Kpa. Part 4 The actions taking place in the engine cylinder can be divided into four stages, 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 TDC 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. The four piston strokes are intake, compression, power, and exhaust. 16. What do we see from the paragraphs? ( ) A. What is stroke? B. What is engine? C. What is cylinder? 17.Which one Statement is true according the above first paragraph? ( ) A. A four-stroke-cycle engine means that four strokes is required 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). 18. What is BDC in the term of automobile industry? ( ) A. Bottom dead center. B. Top dead center. C. Neither of A and B. 19. 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. 20. Which one Statement is TURE according the article? ( ) A. The four piston strokes are intake, compression, power, and exhaust. 第 4 页 共8页 B. The four piston strokes are intake, compression, power, and inhauls. C. The four piston strokes are intake, combining, power, and exhaust. 三、句子英译汉(每小题5分,共25分) Section A Translation English into Chinese Directions: This part is to test your ability to translate English into Chinese. 1. All vehicles must fitted with at least 2 independent brake systems. They were once called the service brake and the emergency brake. 所有汽车都必须配备两套独立的制动系统,即行车制动和紧急制动。 2. The location of the driving axle determines whether the vehicle is classified as rear-wheel drive,front-wheel drive,four-wheel drive or all-wheel drive. 驱动桥的位置决定驱动方式的类型:后驱、前驱、四轮驱动和全轮驱动。 3. We all know that diesel engines, in principle, work in the same way as gasoline engines do. 4. The vehicles are normally consisituted by four parts, such as engine, chasis,body,electrical equipment.
