| Abstract:Based on the data from experiments the impact of delay period on the working condition and performance of direct injection diesel engine is analyzed. The results show that the delay period determines rate of heat release and acceleration and thus determines the changing of pressure in cylinder. By proper controlling of delay period, the dynamic behavior and economical efficiency of diesel engines could be improved and emissions be reduced. |
