要说柴油机和汽油车最大的区别，那就是燃烧方式，汽油机是预混合的火焰传播燃烧，阶段包括进 气→压缩（油气混合物）→点火燃烧（定容燃烧）→排气；柴油机主要是扩散燃烧，进气（纯空气）→ 压缩（纯空气）→喷油自燃（定压燃烧）→排气。 柴油机与汽油机最根本的区别在于点火方式，柴油机采用压燃式（CI Engine，Compress Ignition Engine）点火，而汽油机则依赖火花塞点燃（SI Engine，Spark Ignition Engine）。 柴油机工作时，只吸入空气并将其压缩，随后喷油器将柴油以雾状形式喷入高温高压的空气中，柴 油在压缩空气产生的高温下自行燃烧。这种点火方式决定柴油机不需要复杂的点火系统，如火花塞和高 压线圈。汽油机则不同，它吸入的是空气与燃油的混合物，在压缩冲程接近尾声时，火花塞产生电火花 点燃混合气。 由于柴油机依靠压燃式燃烧，因此燃油喷射压力极高，高的达到2500bar，而汽油机目前量产的第 五代EA888搭载的500bar喷油压力已属"天花板"，对比柴油机的供油压力是"小巫见大巫"。同时，柴油 机由于没有点火系统，省去火花塞等部件的定期更换，总体维护成本较低。但柴油机的喷油嘴和 ...
