Abstract

The combustion process and emission characteristics in diesel engine mainly depend on the mixture formation in cylinder. Spray characteristic is an important factor which affects the mixture formation and combustion process. Further, nozzle hole cone angle of the fuel injector directly influence the spray characteristic. In this paper, flow evolution process, spray distribution, fuel/air ratio equivalence ratio distribution, temperature distribution and emissions formation are analyzed. The results show that: mixture formation quality can be improved if selecting the nozzle hole cone angle appropriately, and therefore combustion process will be improved and emissions will be reduced.
