The higher the rating, the slower the burn when ignited during the compression burn cycle of the piston.

等级越高，输出的燃烧在压缩点火燃烧循环的活塞。

Ignited modes of reciprocating internal combustion engine addition to the spark-ignited and compression engine operation, a third option exists that is Homogeneous Charge compression Ignition (HCCI).

在往复式发动机中，除了火花点燃式燃烧和柴油压燃燃烧的运转方式外还有第3种运转方式，即均质充量压燃燃烧(HCCI)。
