The internal EGR rate is also reduced with increase in the engine load under the same engine rate and scavenging pressure.

在同一转速和扫气压力下，内部EGR率随负荷增大而降低。

The experimental results show that HCCI can obtain high mean indicated heat efficiency up to 60% and mainly be effected by the engine load and hardly by the engine speed.

结果表明：HCCI燃烧有较高的指示热效率，最高可达60%；指示热效率主要受负荷的影响，转速对其几乎没有影响。
