In a diesel engine, there is no spark plug. Instead, diesel fuel is injected into the cylinder, and the heat and pressure of the compression stroke cause the fuel to ignite.

柴油发动机内没有火花塞，取而代之的是将柴油喷入发动机气缸，然后压缩冲程在高温高压下引起燃料点火。

Diesel fuel has a higher energy density than gasoline, so a diesel engine gets better mileage.

柴油比汽油能量密度更高，所以柴油发动机行程更长一些。
