英语翻译
Internal Combustion Engine
The engine is a self-contained power unit which converts the heat energy of fuel into mechanical energy for moving the vehicle.Because fuel is burned within the engine,it is known as an internal combustion engine.In the internal combustion engine,air/fuel mixture is introduced into a closed cylinder where it is compressed and then ignited.The burning of the fuel causes a rapid rise in cylinder pressure which is converted to useful mechanical energy by the piston and crankshaft.The most common engine is the four-stroke piston engine.These four strokes are intake stroke,compression stroke,power stroke and exhaust stroke.

译文：
内燃机
引擎是自备动力装置,它可以把燃料的热能转换成机械能供给汽车运行.因为燃料在引擎内燃烧,所以把引擎称之为内燃机.在内燃机中,空气/燃料的混合物被传入到密闭的汽缸里,在这里混合物被压缩然后着火点燃.燃料的燃烧必然引起气缸的压力迅速升高,迅速上升的压力会通过活塞和曲柄将其转化成有用的机械能.最常用的发动机是四冲程活塞发动机.这四种冲程分别是：进气冲程,压缩冲程,动力（膨胀）冲程,和排气冲程.
