Translate the following sentences into Chinese.1) In the internal combustion engine, an air-fuel mixture is introduced into a closed cylinder where it is compressed and then ignited.2) The intake stroke of a four-stroke engine begins with the piston at top dead center (TDC).3) After the piston reaches bottom dead center (BDC), it moves upward again as the starter continues to turn the crankshaft in a clockwise direction.4) Just as or slightly before the piston reaches TDC on the compression stroke with the air/fuel mixture fully compressed, a timed electrical spark appears at the spark plug.5) The engine cycle has only one power stroke where the piston is actually driving the crankshaft.5. Translate the following passage into Chinese.The engine is considered by most to be the definitive factor of an automobile. It provides the motivational force for the vehicle and drives the electrical and auxiliary systems required for operation. The internal combustion engine changes energy forms to provide propulsion. Combustible materials are detonated to create a forceful explosion (and this expansion of gasses) that is then converted into some form of rotational motion. This rotational force or torque is then applied to the wheels to provide linear motion. Engines can consist of two or four-cycle piston units, turbines, rotary units, or free piston units. The most common is the four-cycle piston engine.Unit 2 Exercises1. Choose the best answer from the following choices according to the text.1) The ______ are circular, tube like openings in the block, which act as guides for the pistons as they move up and down.A. chambersB. cylindersC. boresD. rings2) Manufacturers make most engine pistons from _____, which is less than half the weight of iron.A. ironB. nickelC. chromiumD. aluminum3) _____ describes the escape of unburned and burned gases from the combustion chamber, past the piston, and into the crankcase.A.

Translate the following sentences into Chinese.1) The cylinders are circular, tube like openings in the block, which act as guides for the pistons as they move up and down.2) Many parts are also attached by fastening devices to the engine block.3) Depending on the style of engine, the cylinder head serve many functions.4) If this clearance is too small, for whatever reason, several problems can develop.5) The measurement of this open period is not in units of time because the actual time a valve remains open varies with engine speed.5. Translate the following passage into Chinese.Overhead cam engines use camshafts located above the cylinder head instead of the more common location inside the engine block. This eliminates the use of push rods and rockers creating a tighter valve train less susceptible to float. These engines can operate more efficiently at higher engine speeds than pushrod types.Unit3 Exercises1.Choose the best answer from the following choices according to the text1) The has the job of supplying a combustible mixture of air and fuel to theengine.A. stating systemB. cooling systemC. lubricating systemD. fuelsystem2) Electronic Fuel injection system can be divided into basicsub-systems.A. twoB. threeC. fourD. five3) To maintain precise fuel metering, the fuel pressure regulator maintains aconstant fuel .A. pressureB. flowC. velocityD. quality4) The monitors variables such as coolant temperature, engine speed,throttle angle, and exhaust oxygen content.A. sensorB.

Translate the following sentences into Chinese1) The fuel system has the job of supplying a combustible mixture of air and fuel to the engine.2) Fuel is pumped from the tank by an electric fuel pump, which is controlled by the circuit-opening relay.3) Fuel injection volume determination is based upon the value of input sensor signals.4) By delivering fuel directly at the back of the intake valve, the intake manifold design can be optimized to improve air velocity at the intake valve.5. Translate the following passage into ChineseWhen the throttle valve is opened, air flows through the air cleaner, through the air flow meter(on L-type systems), past the throttle valve, and through a well tuned intake manifold runner to the intake valve. As the throttle valve is opened further, more air is allowed to enter the engine cylinder, Some engines use two different methods to measure intake air volume. One of EFI type system measures air flowdirectly by using an air flow meter. The other type of EFI system measures air flow indirectly by monitoring the pressure in the intake manifold.Unit 4 Exercises1.Choose the best answer from the following choices according to the text1) In an automobile engine, heat flows or transfers from the iron or aluminum cylinder to the cooling water, and from the coolant to the copper oraluminum .A. pumpB. radiatorC. pistonD. fan2) When water freezes, it expands approximately percent in volume.A. sevenB. eightC. niceD. ten3) Most cases of lost are due to excessive clearance in the bearings ofthe enginerather than worn oil pumps.A. oil pressureB. water pressureC. oil temperatureD. oil viscosity4) Oils used in automobiles need some to improve their characteristics.A. additivesB. antifreezeC. lubricantD. coolant2.

Translate the following sentences into Chinese1) Excessive friction in the engine, however, would mean rapid destruction.2) In order to reduce the formation of rust, commercial antifreeze contains an inhibitor designed to prevent corrosion.3) Air-cooled engines were used successfully in the early days of the automobile.4) The requirements of today’s automobile engines are far beyond the range of straight mineral oils.5. Translate the following passage into ChineseA car’s cooling system is one of its most vital components. Engines rely on their cooling systems to remove immense amounts of heat that if allowed to accumulate would cause engine failure. There are two types of cooling systems; air cooled and liquid cooled engines. Air-cooled engines utilize metal fins that radiate off the combustion chamber. These fins provide greater surface area to radiate heat into the air. This is utilized extensively on motorcycle engines and also the Porsche flat six is a automotive air-cooled engine. A liquid cooling system is a series of fluid pathways that transport a cooling fluid. This fluid is usually a 50/50 mixture of antifreeze to water. This fluid removes heat from the engine as it flows through passageways cast into the engine block. This fluid circulates to a radiator that has many metal fins. Cars have grilles and louvers that direct air flow across the radiator releasing heat into the air.Unit 5 Exercises1.Choose the best answer from the following choices according to the text1) The on an internal, combustion engine provides the spark that ignites the combustible air/ furl mixture in the combustion chamber.A. stating systemB. cooling systemC. ignition systemD. fuelsystem2) The purpose of the ignition switch is to connect and disconnect the ignitionsystem fromthe , so the engine can be started and stopped as desire.A. batteryB. starterC. radiatorD. distributor3) The provides the power to turn the internal combustion engine over until it can operate under its own power.A. fuel systemB. cooling systemC. ignition systemD. starting system4) The battery supplies in the form of current flow for the starting circuit.A. electrical energyB. mechanical energyC. chemical energyD.heat energy2. Translate the following into Chinese.1) spark plug 2) battery 3) distributor4) armature 5) commentator 6) ignition system7) starting system 8) brush 9) field coil3. Translate the following into English1) 点火线圈2）初级线圈3）分电器盖4）启动机电磁开关5）点火提前6）点火正时7）点火分电器8）启动机9）点火开关4. Translate the following sentences into Chinese1) The purpose of the ignition condenser is to reduce arcing at the breaker points, and prolong their life.2) A distributor rotor is a conductor designed to rotate and distribute the high tension current to the tower s of the distributor cap.3) This insures a strong spark during the crankshaft period, and in that way quicker starting is provided.4) The armature is the only rotating component within the starter.5. Translate the following passage into ChineseThe starter is the device that is responsible for initiating the rotational motion of the engine. This device replace the old style hand cranks found on many very early cars. The starter works on a switched circuit with the ignition key. When the key is turned the starter receives power from the battery. This power then engages a clutch that pushes the starter gear to the gear on the flywheel of the engine. The motor then turns, thus turning the engine. When the engine reaches speed, or the power is removed, the gear retracts to prevent damage to the teeth.Unit 6 Exercises1.Choose the best answer from the following choices according to the text1) When oil is being consumed by passing through the engine, it usually will case heavyto come from the exhaust, particularly after the engine has idled for several minutes.A. black smokeB. blue smokeC. white smokeD. steam2) Out-of-balance tires and propeller shafts are the most common causes ofvibration.A. chassisB. engineC. bodyD. flywheel3) An abnormal sound originating from some form of piston-ring problem is audible during engine .A. startingB. stopC. decelerationD. acceleration4) The one abnormal sound unrelated to worn, damage, loose, or maladjusted engine parts is .A. piston slapB. piston-pin knockC. main bearing noiseD.detonation knock2.

Translate the following into English1) 活塞敲缸2）发动机过热 3）发动机异响4）水垢5）活塞销6）爆震敲击7）机油消耗8）发现并处理故障9）临界速度4. Translate the following sentences into Chinese1) All surface of the radiator and its hose connections should be carefully inspected.2) It is not too unusual for cracks to form in the engine water jacket.3) A sound not frequently heard in an engine is that of a piston ring striking the ring ridge at the top of the cylinder4) The one abnormal sound unrelated to worn, damage, loose, or maladjusted engine parts is detonation knock.5) Excessive clearance in the valve train produces a noise that is usually more apparent during engine idle rpm than any other time.6) L loose vibration damper or flywheel can also cause abnormal engine noises.5. Translate the following passage into ChineseSludge is a mayonnaise(蛋黄酱) –like mixture of water, oil, dirt and other products of combustion. It is most likely to form in an engine that seldom reaches a satisfactory operating temperature. Slow speed, stop-and-go operation means that the engine seldom gets hot enough to drive the water and vapor out of the crankcase. The water condenses on the cold walls of the crankcase or in some cases gets into the crankcase through leaking cylinder head gaskets. This water emulsifies with the oil, carbon, dirt, etc., to form sludge.。

Engine The engine acts as the power unit. The internal combustion engine is most common: this obtains its power by burning a liquid fuel inside the engine cylinder. There are two types of engine :gasoline(also called a spark-ignition engine) and diesel(also called a compression-ignition engine).Both engines are called heat engines; the burning fuel generates heat which causes the gas inside the cylinder to increase its pressure and supply power to rotate a shaft connected to the transmission.
