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.

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。

Our model considers heat leak between cylinder wall and environment in combustion process, internal irreversibility of cyclic working fluid in adiabatic processes, and cycle time.

模型考虑了燃烧过程气缸壁与环境间的热漏、循环工质在绝热过程中的内不可逆性以及循环时间的影响。

The combustion of hydrogen in either an internal combustion engine or a fuel cell generates only water, and the cycle is closed for a comprehensive overview see Ref.

不论在燃烧氢内燃机或燃料电池产生只有水和周期是关闭的总览见参考。

The authors do not analyse individual countries, but Majeau-Bettez estimates that the global warming impact of an EV car driven in the UK is about 10% better over its life cycle than that of a car with an internal combustion engine.
