Among other available heat engines, the stifling engine embodies some interesting features: high efficiency, low noise and vibration as well as the ability to use the sources of high energy density.
在其他各种热动力中，热气机具有许多特点：高效率，低噪音和振动，以及可利用高能量密度的各种热源等。
Through experiment, the relation figures of engine rotation speed, coefficient of performance of heat pump and engine thermal efficiency are presented and analyzed.
通过实验，得出了发动机转速与热泵性能系数、发动机热效率的关系曲线，并进行了分析。
The rest of the heat may be allowed to escape, or, for maximum engine efficiency, the steam may be condensed in a separate apparatus, a condenser, at comparatively low temperature and pressure.
剩余的热可以排放，或者蒸汽可在单独的冷凝器中于较低的温度和压力下冷凝，以便获得最大的蒸汽机效率。
