3、le 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.

4、 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 r

5、esource 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.C. The automobile engine is an inner combustion engine3. What do we see from the second paragr

6、aphs? ()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 cranks

7、haft.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.C. Both A and B are false.Part 2Th

8、e engine also needs a cooling system; the combustion of the airfu- el ?The mixture in the engine creates a very high temperature (as high as 2000C to 2700 C°). T°he cooling system takes heat away from the engine by circulating a liquid coolant (water mix with antifreeze) between the engine

9、 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?

10、()A. a cooling system is must for the engine .B. The engine don't need a cooling systemC? 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 C t°o 2700 C°.B. As high as 1300 C t°o 2000 C°.C. No

11、t higher than 2000 C. °8. What is liquid coolant? ()A. water mix with antifreezeB. water used by the cooling system?C. Any liquid used by the cooling system.9. What do we see from above paragraph? ()A. The coolant gets HOT as it goes through the radiatorB. The coolant gets COOL as it goes throu

12、gh the radiatorC. 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 3Power stroke: As the piston reaches TDC on the compressi

13、on 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 bum very rapidly, and the cylinder pressure increases to as

14、 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 pa

15、ragraph?( )A. Power strokeB. 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.

16、 Which word or phrase can change the word“ ignite)s"?(A. sets fire toB. shoots atC. charges14. 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-volt

17、age 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.15. When the air-fuel mixture beings to burn very rapidly, how much does the cylinder pressure increase to?( )A. As much as 3-

18、5 Mpa or even more.As much as 3-5 bar or even mocC. About 3-5 Kpa.Part 4The actions taking place in the engine cylinder can be divided into four stages, or stroke. ， ' refers to piston movement; a stroke occurs when the piston moves from one limiting position to the other. The upper limit of pis

19、ton 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 ev

20、ents 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. W

21、hat 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 cal

22、led TDC (top dead center).1 & 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 fou

23、r 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.B. The four piston strokes are intake, compression, power, and inhauls.C?
