| 摘 要： | 针对改进型双燃料发动机燃烧效果较差的问题,采用一维仿真的方法,建立了R6160双燃料发动机模型。应用此模型研究了喷油正时、天然气喷气正时和过量空气系数对燃烧的影响;对喷油正时和天然气喷气正时的改进效果进行了试验验证。试验结果表明:合理调整喷油正时和天然气喷气正时能有效改进双燃料发动机的性能。

| Abstract: | Aiming at the inferior combustion of the modified R6160 dual fuel engine, 1-D simulation method was employed to establish the engine''s model. Based on this model, the influence of fuel injection timing, natural gas injection timing and excess air coefficient on combustion was studied. The effect of improved fuel injection timing and natural gas injection timing was verified through experiments. The results showed that the performance of engines could be improved by reasonably adjusting fuel injection timing and natural gas injection timing. |
