| 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. |
