1 发动机分类和一般力学
汽车发动机可按规定分类:(1)循环,(2)冷却系统,(3)燃料系统,(4)点火方法,(5) 阀门布置,(6)汽缸布置,(7)发动机速度。
汽车中使用的发动机是内燃热机。在发动机中起动的燃烧在发动机燃烧室中产生高压,这个高压力活塞运动时,运动由连杆承载到发动机曲轴上,曲轴因此被转动:旋转运动通过动力传动系传递到车轮,从而它们旋转并且车辆移动。
发动机需要运行四个基本系统(图2-1)。柴油发动机需要这些系统中的三个。它们是燃油系统,点火系统(柴油除外),润滑系统和冷却系统。但是,其他三个相关系统也是必要的。这些是排气系统,排放控制系统和起动系统。每系统都在执行引擎运行的基本工作。

1 Engine Classification and Overall Mechanics
The automobile engines can be classified according to: (1)cycles,(2)cooling system,(3)fuel system,(4)ignition method,(5)valve arrangement,(6)cylinder arrangement,(7)engine speed.
Engines used in automobiles are the internal combustion heat engines. The burning of gasoline inside the engine produces high pressure in the engine combustion chamber, this high pressure force piston to move, the movement is carried by connecting rods to the engine crankshaft, 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. |
