压缩冲程

An alternative is the two-stroke cycle, which combines the exhaust and compression strokes into one.

另一种循环是两冲程循环，它把排气冲程与压缩冲程合并为一个冲程。

An alternative cycle is the two-stroke cycle, which combines the exhaust and compression strokes into one.

另外一种循环方式是二冲程循环，这种循环把排气冲程与压缩冲程结合成一个冲程。

The results of this study indicate that changing the angle of the intake port has a profound effect on the flow field during the intake stroke of the engine cycle. For the case with the intake-exhaust valves canted at zero degree (the so-called vertical valves), the tumble ratio, swirl ratio, turbulent intensity, and turbulent kinetic energy in the direction perpendicular to the bisecting plane of the cylinder are at their highest levels than those obtained for the other cases. This effect is most pronounced after the compression stroke of the cycle. As a result of this study, it is observed that the behavior of the overall flow field from the intake to the completion of compression stroke has a major impact on the effectiveness of the mixing of fuel-air prior to the ignition of the engine cycle.

结果显示，改变进排气阀的倾斜角度对进气期间的流场变化有很明显的影响，其中以垂直阀(进排气阀倾斜0度)所得的 Y轴向(Y方向系垂直於将汽缸对分为二平面的方向)滚流强度、涡漩比、紊流强度、紊流动能等流场强度为最强；若以流体经活塞压缩后的流场特性进行探讨，所得结果显示压缩冲程对汽缸内流场的效应是不容忽视的；因此由进气到压缩过程结束的整体流场现象，才是影响引擎点火前的油气混合程度与燃烧品质的关键。

Compression stroke The second stroke is the compression stroke.

压缩冲程第二冲程是压缩行程。

As the piston rises again on the compression stroke the charge is compressed and ignited, and the cycle begins again.

当活塞再度升向压缩冲程时，混合气被压缩并点燃，循环再度开始。

A control apparatus for an engine increases an intake air quantity just before engine stop to increase a compression pressure in a compression stroke.

一种发动机(11)的控制装置(30)，用于在发动机停止之前增加进气量从而增加了压缩冲程中的压缩气压。

As the compression pressure is increased, a negative torque in the compression stroke increases and obstructs engine rotation, and brakes the engine rotation.

随着压缩气压增加，压缩冲程中的负转矩也增加并阻碍发动机旋转，从而停止发动机旋转。

While Atkinson's original engine design is no more than a historical curiosity, the Atkinson cycle, where the power stroke is longer than the compression stroke, is increasing in popularity due to the increase in fuel economy it provides.

尽管阿特金森的原发动机的设计，只不过是历史的好奇心，在阿特金森循环，其中动力冲程长度超过压缩冲程，是越来越受欢迎，由于在燃油经济增长提供。

The highly efficient Atkinson-cycle engine, made possible by the Variable Valve Timing with intelligence system, allows the expansion/power stroke to be longer than the compression stroke so that combustion energy can be more effectively used for production of engine power.

高效的阿特金森循环发动机，作出与智能可变气门正时系统，可以使扩充/动力冲程要长于压缩冲程，使燃烧的能源可以更有效地用于生产发动机力量。

The compression, power, and exhaust strokes are identical to those of the diesel cycle.

其它3个冲程（压缩冲程、动力冲程、排气冲程）与柴油活塞循环相同。
