| Abstract: | This paper introduces the effect and influence of the parameters of nozzles for reduction on exhausts emission levels in DI diesel. At the condition of the changeless combustion chamber shape, it was researched that how to match the reasonable parameters of nozzles in DI diesel. Also a method is put forward that using the different height of the spray impingement points to analyze the effects of the spray spatial angles parameters on matching between combustion chamber and nozzles. |
