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。

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.

我们已经了解油气混合燃料是如何通过燃料供给系统输送到发动机气缸，并在气缸中压缩、点火、燃烧的。

We have seen how the mixture of air and fuel is delivered by the fuel system to the engine cylinder, where it is compressed, ignited, and burned.
