A proper design of the compression ignition engine fuel system requires various fuel injection methods analysis. Direct and indirect CNG injection process simulation research was conducted. The results allow a mixture homogeneity analysis and its impact on combustion process and heat transfer. For an indirect injection the injector is placed in intake channel and the injection is performed during an intake stroke. For a direct injection the specially designed injector is installed in the glow plug position. The analysed case is set for 20% energetic ratio of diesel fuel and 80% of methane fuel. In order to perform the calculations a special combustion model has been implemented that allows duel-fuel combustion in a compression ignition engine.
