I have to summarize the advantage of the new type engine and the causes.
The advantage is: higher efficiency than current engine.
I try to explain the causes in popular language: 1. Beside the common method to increasing the pressure (by blower/compressor), the new type engine uses another method to increase the gas pressure further (by the closed combustion). The gas has higher pressure before it works, it will has higher efficiency (according to thermodynamics).
2. The efficiency of blower/compressor isn’t high, especially in very high-pressure stage. but the compressor will spend a lot of energy from burnt gas in current turbo-engine. (about 2/3). At this aspect the new type engine also has higher efficiency comparatively.

How to demonstate the advantage in detail: pls see the reply#59 in page6 about the analyse of working circle by theory;reply#226 in page23;reply#235 in page 24; ther are also some other replies to explain why the increase rate only by combustion has the such times that listed in the examples.
