热量利用 meaning in Chinese

heat recovery

Thermal utilization factor
热利用系数热量利用因数
Calculation and application of fuel heat utilization factor of marine diesel engine
船用柴油机燃料热量利用系数的计算与应用
The results of study show that the transmitting speed of flame is slower and the combustion duration is longer than gasoline . the combustion status of lpg is improved , but the problem of long combustion duration also exists when speed and load are increased . it is useful to adjust ignition timing , but nox emission increase
通过研究认识到： lpg燃烧时火焰传播速度比汽油慢，燃烧持续期比汽油长；随着转速和负荷的增大， lpg燃烧状况得到改善，但仍出现后燃期长，热量利用不充分等问题；点火提前角的调整有利于lpg的燃烧，但使nox排放升高。
