Concurrently analyzed is that improvement of effective thermal efficiency 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。

It is also found that the fuel consumption increases with the decrease of firing cycle time, and cutting down the air infiltration will be helpful for saving fuel.
