Abstract: The combustion process in spark-ignition engines is simulated using a multi-dimensional simulation method similar to that of Ahmadi-Befrui et al. The turbulence characteristics are described by the k-ε model that is modified by taking into consideration the results of in-cylinder measurements. An empirical constant for the combustion submodel is determined by optimum matching of the predicted cylinder-pressure courses with the measured ones. Calculations reasonably reproduce the measured course of combustion. Furthermore, a discussion is given on the effects of induction swirl and fuel-air equivalence ratio on combustion process.
