由于在制冷剂流入压缩空间前制冷剂不会回流，所以能够提高压缩效率。

As the refrigerant does not flow backward before it flows into a compression space, it is possible to improve the compression efficiency.

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。

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.
