Zero-dimensional knock simulations have been performed by using the model proposed by Noda et al. [SAE technical paper 2004-01-0618] implemented in CHEMKIN-PRO software. A detailed chemical kinetic mechanism for fivecomponent gasoline surrogate was used with composition corresponding to JIS 2nd-grade gasoline (RON=90.8 and MON=82.9). An interesting effect of the cool flames appearing before the compression by flame propagation on the knocking was observed, which was suggested to play a key role in the recent development of SI engines. Present study implies that the modeling with kinetic mechanisms can be a powerful tool for technology breakthrough of next generation combustion engines.
