高压喷射乙二醇双燃料发动机的燃烧与排放特性研究
Combustion and Emission Characteristics of a Diesel Dual Fuel Engine with High Pressure Injection of Ethylene Glycol
为了提高发动机的动力性能以及降低污染物排放水平，在一台直列4 缸涡轮增压共轨柴油机上，研究不同高压喷射乙二醇（EGP5、EGP10、EGP20）在不同替代率（EG0、EG5、EG10、EG15）下对发动机燃烧与排放特性的影响。研究结果表明：在相同喷射压力（EGP）下，缸内峰值压力和峰值放热率随着乙二醇替代率的增加，呈先下降后上升的趋势；随着乙二醇喷射压力的增加，缸内平均温度也随之增加，滞燃期基本不变，燃烧持续期略微缩短，而且NOx 排放量随着替代…查看全部>>
In order to improve the engine's power performance and reduce pollutant emissions, the effects of different high-pressure injection of ethylene glycol (EGP5, EGP10, EGP20) on the engine's combustion and emission characteristics under different substitution rates (EG0, EG5, EG10, EG15) were studied on an inline 4-cylinder turbocharged common rail diesel engine. The research results show that under the same ethylene glycol injection pressure (EGP), the peak pr…查看全部>>
