The four strokes in the four-stroke-cycle engine, in their proper order, are intake, compression, power, and exhaust.
四冲程发动机本与此同进气阀运动类型的类型，但以使增压器的功率损耗密度，这些都是为米勒循环发动机众所周知的。
Four-stroke engines of this type with this same type of intake valve motion but with a supercharger to make up for the loss of power density are known as Miller cycle engines.
奥托制造了第一台实用的四冲程内燃机，叫做“奥托循环发动机”，并且当完成制造他的发动机后他就把发动机安装在摩托车上。
Otto built the practical four-stroke internal combustion engine called the "Otto Cycle Engine, " and as soon as he had completed his engine, he built it into a motorcycle.
虽然修改奥托循环发动机使用“阿特金森循环”提供良好的燃油经济性，这是比较传统的四冲程发动机在一个较低的功耗，每位移费用。
While a modified Otto cycle engine using the "Atkinson cycle" provides good fuel economy, it is at the expense of a lower power-per-displacement as compared to a traditional four-stroke engine.
