Translate the following sentences into Chinese. 1.All automobile engines, both gasoline engine and diesel engine, are classified into internal combustion engines because the combustion or burning that creates energy takes place inside the engine. 译文：由于所有的汽车发动机，包括汽油机和柴油机在内，产生能量的 燃烧都发生在发动机内部，所以它们都被称为内燃机。 2. Cars equipped with automatic transmissions normally do not have a clutch, on these, the transmission operates automatically so that the driver is not required to use a clutch to shift gears. 译文：装有自动变速器的汽车通常没有配离合器，变速操作是自动的因 此不需要驾驶员通过踩离合器进行换挡。,Answers of Exercises,3. In addition, it provides a cushioning effect through the use of padded interiors, a compliant windshield, and an energy absorbing steering column and dash, all of which help ameliorate the impact of an unrestrained occupant against the interior of the passenger compartment. 译文：另外，为了缓解行撞，进行内部加垫处理、采用平顺的风窗玻 璃、装有能量吸收式转向柱和缓冲器，所有这些措施都可以减少车内未 系安全带的乘员所受到的行击。 4. The purpose of the battery is to supply current for operation of the cranking motor and the ignition system when the engine is being cranked for starting. 译文：蓄电池的作用是当发动机正在起动时，为起动机和点火系统提供 电流。,Answers of Exercises,IV. Review the following questions according to the texts. Q1:Please list the name of the four strokes cycle, and explain the working principle of the four stroke cycle. The four strokes refer to intake, compression, combustion and exhaust strokes that occur during two crankshaft rotations per working cycle of the gasoline engine and diesel engine. Q2. How many parts does the chassis consist of? Transmission system, driving system, steering system and braking system.,Answers of Exercises,Q3. Please write down every part function of the chassis. The clutch is a device to engage and disengage power from the engine, allowing the vehicle to stop and start. The function of the transmission is to transmit the power and torque from the engine to the wheels. The propeller shaft is the drive shaft which carries the power from the transmission to the rear-wheel axles. The differential is part of the rear-axle-housing assembly, which includes the differential, rear axles, wheels and bearings. The suspension system has two basic functions. First, keep the cars wheels in firm contact with the road. Second, provide a comfortable ride for the driver and passengers. The purpose of the steering system is guiding the car where the driver wants it to go. The brake system is used to slow down and stop a vehicle.,Q4. Please give examples of several forms and features of body. Pickup Truck, A small, medium, or large-sized truck, though smaller in every case than a Semi tractor truck. The passenger cabin is wholly separated from the cargo bed. Convertible Vehicle, A body style with a flexible textile folding roof or rigid retracting roof of highly variable design detail to allow driving in open or enclosed modes. Q5. Please write the types of car lights and the roles of the lights. The backup lights come on when the driver shifts into reverse. Blinker lights are installed on many cars to provide a means of signaling when a car is stalled on the highway or has pulled off to the side.,Answers of Exercises,
