The piston travels down on the Intake stroke ,up on the Compression stroke ,down on the Power stroke and up on the Exhaust stroke.
Just like that of a manual transmission ,the automatic transmission"s job is to allow the engine to operate in its narrow range of speeds while providing a wide range of output speeds to drive the car, whether it is forwards or backwards.

活塞在进气冲程和压缩冲程，动力冲程和排气冲程彼此间运动。就像那个手动传输，自动传输工作就是当提供大范围的产品速度来驱动汽车时，能允许引擎自己操纵它狭窄范围内的速度，无论结果是向前进还是倒退。engine lubrication system 引擎润滑系统full-slipper piston
