...分循环设计,具有两个高压冲程压缩冲程(Compression Stroke)和做功冲程(Power Stroke);以及两个低压冲程吸气冲程(Intake Stroke)和排气冲程(Exhaust Stroke)。做功冲程属于被动工作(Positive Work),换而言之气体膨胀产生能量推动机械工作。

exhaust-and-intake stroke 排气进气行程
The piston travels down on the intake stroke, up on the compression stroke, down on the power stroke and up on the exhaust stroke.
进气行程,活塞下行;压缩行程,活塞上行;做功行程,活塞下行;排气行程,活塞上行。
The intake stroke starts with the pistonat the top of the cylinder (intake valve open and exhaust valve closed) and stops with the pistonat the bottom of its travel.
进气冲程在活塞位与气缸顶部(进气门开启,排气门关闭)时开始,在活塞到达其行程的底部时结束。
