天然气喷气压力和喷气相位对天然气/柴油双燃料发动机性能的影响

Effect of Injection Pressure and Phase Position of Natural Gas Performance on Natural Gas/Diesel Double Fuel Engine

采用电控喷气技术实现天然气 /柴油双燃料发动机的天然气供气方式 ,可使发动机具有良好的动力性、经济性及排放特性。而天然气的喷气压力和喷气相位对发动机的动力性、经济性及排放性能有着较大的影响 ,本文对此进行了研究。

The introduction of the feed method of natural gas in the double fuel engine of the natural gas/Diesel by the technique of electronically controlled gas injection makes the engine have better performance in power,economy and emission.The injection pressure and phase position of natural gas have a great effect on the performance of engine.The article presents the study of the injection pressure and phase position of the double fuel engine of the natural gas/diesel.
