The combustion process of natural gas in a premixed charged compression ignition (PCCI) engine is analyzed using computational fluid dynamics via stochastic approach. The nonuniform states of turbulent mixing and the ignition process are statistically described using probability density function (PDF). The results show that the course of in-cylinder pressure is good agreement with experimental data, and the effect of mixture heterogeneity on the ignition delay and the rate of heat release is revealed.
