Abstract

The mechanism of low speed pre-ignition (LSPI) and knock process in boosted direct injection spark ignition (DISI) gasoline engines are researched in this study. A single cylinder boosted DISI engine test bench was set up and operated at LSPI caused by oil, whose results are used to verify the feasibility of the calculation models. The geometric model is therefore established and the numerical simulation working at different injection times when the engine speed at 1200rpm and 1600rpm are conducted with the AVL FIRE CFD software.
