排气冲程

这四招进气行程，紧缩行程，动力冲程和排气冲程。

These four strokes are intake stroke , compression stroke , power stroke and exhaust stroke .

当偏置电压增至5kV时，不仅燃烧过程中有离子电流信号，而且在进、排气冲程中，离子电流信号也异常突出。

During the combustion process single high apex or double apices or three apices of ionic current have been found when the bias voltage increases .

配气机构控制着发动机的进气冲程与排气冲程两个工作过程，对发动机的性能特性和可靠性有着直接的影响。

The valve train controls the intake and exhaust strokes of the engine , which has a direct impact on its performance and reliability .

通过分析振动信号各成份在一个周期内的分布情况，提取了干扰较少的排气冲程阶段信号，并在消除了相邻缸的振动影响后，作为活塞缸套磨损的特征相位段。

The composition and distribution of vibration signals in a working cycle was analyzed , the exhaust-stroke signals were extracted owing to less disturbance and used as characteristic phase of piston-liner wear after the elimination of adjacent cylinder disturbance .
