The paper sheds light on a fundamental issue of knocking combustion, i.e., mechanisms of pressure wave generations and autoignition in end-gas region. The results from our recent numerical simulations, where a knocking combustion is modeled using a one-dimensional constant-volume reactor, are introduced and discussed with a survey of relevant previous studies. The importance of the negative temperature coefficient on the mechanisms of strong pressure wave generations and the location of autoignition position in end-gas region is clearly highlighted. The paper also presents a strategy for efficiently handing detailed chemical kinetics mechanisms in computational fluid dynamics simulations.
