汽车发动机（内燃机），可燃气体在其内部和空气混合燃烧，燃烧后产生的高温高压气体，膨胀做功，推动活塞运动，将化学能转化为可用的机械能。
An internal combustion engine (ICE) is a heat engine where the combustion of a fuel occurs with air in a combustion chamber. The expansion of the high-temperature and high-pressure gases produced by combustion apply direct force to pistons. This force moves the component over a distance, transforming chemical energy into useful mechanical energy.
