发动机是汽车的心脏,为汽车的行走提供动力,汽车的动力性、经济性、环保性.简单讲发动机就是一个能量转换机构,即将汽油(柴油)的热能,通过在密封汽汽缸内燃烧气体膨胀时,推动活活塞作功,转变为机械能,这是发动机最基本原理.发动机所有结构都是为能量转换服务的,虽然发动机伴随着汽车走过了100多年的历史,无论是在设计上、制造上、工艺上还是在性能上、控制上都有很大的提高,其基本原理仍然未变,这是一个富于创造的时代,那些发动机设计者们,不断地将最新科技与发动机融为一体,把发动机变成一个复杂的机电一体化产品,使发动机性能达到近乎完善的程度,各世界著名汽车厂商也将发动机的性能作为竞争亮点.
汽车一般由发动机、底盘、车身和电气设备等四个基本部分组成.其中,汽车发动机是汽车的主要动力来源.
汽车发动机：发动机是汽车的动力装置.由2大机构5大系组成：曲柄连杆机构；配气机构；燃料供给系；冷却系；润滑系；点火系；起动系.
1.冷却系：一般由水箱、水泵、散热器、风扇、节温器、水温表和放水开关组成.汽车发动机采用两种冷却方式,即空气冷却和水冷却.一般汽车发动机多采用水冷却.
2.润滑系：发动机润滑系由机油泵、集滤器、机油滤清器、油道、限压阀、机油表、感压塞及油尺等组成.
3.燃料系：汽油机燃料系由汽油箱、汽油表、汽油管、汽油滤清器、汽油泵、化油器、空气滤清器、进排气歧管等组成.
4.启动系：起动机 点火开关 蓄电池
5.点火系：火花塞 高压线 高压线圈 分电器
6.曲柄连杆机构：连杆 曲轴 轴瓦 飞轮 活塞 活塞环 活塞销 曲轴油封
7.配气机构：汽缸盖 气门室盖罩 凸轮轴 气门 进气歧管 排气歧管 空气滤 消音器 三元催化 增压器 中冷器等

The engine is the heart of the automobile,as automobile travel,vehicle performance,efficiency,environmental-friendliness.Simply speak the engine is an energy transformation sector,will soon be gasoline (diesel) of thermal energy,sealed in the steam cylinder combustion gas expansion,push live piston power,transformed into mechanical energy,this is the most basic principle of the engine.Engine all structures are as energy transformation services,although the engine with the car passed 100 years of history,whether it is in the design,manufacture,process or performance,control has greatly increased,its basic principle still hasn't changed,this is a creative time,the engine designers,the latest technology and foremost engine engine into a complex Mechatronic products,so that the engine performance achieved near-perfection,the world's leading automotive manufacturers are the engine's performance as competition highlights.
The car generally by the engine,chassis,body and electrical equipment,four basic parts.Where the engine is a major power sources.
Engine:engine is the car's power plant.Consists of 2 large organizations 5 series:crank; valve; fuel supply line; cooling system; lubrication system; ignition system; starting line.
1.the cooling system:General water tanks,pumps,heat sinks,fans,thermostat,water temperature and water switch.The engine uses two types of cooling; air cooling and water cooling.General Motors engines use water cooling.
2.lubrication system:engine lubrication system set by the oil pumps,filters,oil filter and oil road,limiter,oil table,interested tamponade and tapes,etc.
3.fuel system:gasoline engine fuel system consists of the gasoline tank,gasoline,gasoline,fuel filter,fuel pump,carburetor,air filters,inlet and exhaust manifold,etc.
4.start line:starter battery ignition switch
5.high-voltage spark plug ignition system:high-voltage line rings distributor
6.the crank:crankshaft and connecting rod flywheel piston ring piston pin crankshaft seal
7.the valvetrain:valve cylinder head cover camshaft valve intake manifold exhaust manifold air filter muffle-way catalytic supercharger intercooler,etc.
