The influence of split injection on the low speed performance of gasoline direct injection(GDI) engine was researched experimentally with full load at the operating point of 2000r/min using a series of injection modules
focusing on the effect of split injection on power and fuel economy. And the mechanism of the effect of split injection on the engine performance at low speed was investigated by analyzing the changes of cylinder pressure
combustion and emissions. The result indicates the optimized split injection generating the stratified stoichiometric mixture in the combustion chamber can accelerate the flame propagation
and improve the power and fuel economy by 5% and 6% respectively.
