Under the load characteristic of operation, the brake specific fuel consumption and effectivethermalefficiency is almost similar to that of gasoline engine.
在负荷特性工况运行时，混合燃料发动机的有效燃料消耗率和有效热效率与汽油机基本相当；
2
Concurrently analyzed is that improvement of effectivethermalefficiency after rise in compression ratio and water injection is resulted from thermal efficiency promotion of fuel-air ideal cycle.
同时分析了提高压缩比并掺水蒸气后有效热效率提高的主要来源是燃料—空气理想循环热效率的提高。

The impacts of the effective energy fraction and the thermalefficiency of each subsystem are also analyzed.
