Main components of engine:engine crankcase and cylinder block (曲轴箱和气缸体);cylinder head（气缸盖）; piston（活塞）; connecting rod (连杆)；crankshaft(曲轴)；flywheel(飞轮)Chassis :clutch离合器, transmission变速箱, universal joint万向节, drive shaft传动轴,final drive主减速器,differential差速器,axle shaft.填空题The chassis itself is divided into four systems including transmission system,suspension system,steering system and brake system.翻译从功能说，制动系统可分为行车制动系统和驻车制动系统。
Functionally,the brake system can be divided into wheel brake mechanism and parking brake mechanism.悬挂系统用来吸收路面震动，减少冲击和传到簧上的动态载荷。
The suspension system is used to absorb the road shocks and reduce the impact and dynamic loads which are transmitted to the sprung weight.当混合物被压缩时，不仅在气缸里的压力上升，而且温度也上升。
When the mixture is compressed,not only dose the pressure in the cylinder go up,but also the temperature increases. The crankshaft can change the reciprocating motion of the piston into rotary motion and handles the entire power output.The connecting rod is attached to the crankshaft at one end and to the piston at the other end.内燃机的配气机构能定时地将新鲜的混合气充入气缸，并且将废气从气缸中排出。
The valve gear of an internal combustion engine provides timely admission of the fresh charge into cylinders and exhaust of spent gases form them.这意味着只有均等地处理热能以保持发动机温度的均衡，发动机才能有效地工作。
This means that the engine can work effectively only when the heat energy is equally so as to keep the engine temperature in balance.The purpose of the cooling system is to keep the engine at its most efficient operating temperature at all speeds under all driving conditions.由于机油滤清器阻止了杂质微粒进入发动机，这就降低了发动机部件的磨损率。
As these particles of foreign matter are prevented from entering the engine by oil filter,the rate of wear of engine parts is reduced.汽车工程师们不断朝着减少燃油消耗和排放更干净的目标努力。
Automobile engineers are continually striving towards minimal fuel consumption and cleaner exhaustemissions.曲轴箱里的蒸汽可稀释可燃混合物，因此蒸汽的量必须要认真控制和测定，以免影响发动机的性能。
These vapors dilute the air fuel mixture,so they have to be carefully controlled and metered so as not to affect the performance of the engine.空气滤清器在发动机上用于滤清杂质，从而提供顺畅的空气流进入发动机。
The air filter is used in the engine to trap contaminants,yet provide a free flow of air into the engine.The drive line consists of the parts from the back of the flywheel to the wheels.These parts include the clutch,the transmission,the drive shaft,and the final drive assembly.为了使汽车停止而使发动机继续转动，要断开车轮和发动机之间的连接。
To order for a car to stop without stalling the engine,the wheels need to be disconnected from the engine somehow. 转向系除了对车辆控制有着重要的作用外，还与前悬架、车桥、车轮、轮胎等部件有着密切的联系。
In addition to its vital role in vehicle control,the steering system is related to front suspension,axle,and wheel tire components.实际上，大多数汽车的前轮采用盘式制动，后轮采用鼓式制动。
Practically most modern cars have disc brakes on the front wheels,and drum brakes on the rear wheels.若有车轮将抱死，控制器将向液压装置发出信号，维持或减少在相应车轮上的制动液压。
