This paper presents the numerical analysis of a premixed combustion, four stroke, single cylinder engine, by using methane fuel. The Computational Fluid Dynamics (CFD) code FLUENT was used for numerical analysis. The numerical modeling was solved by taking into consideration the effect of premixed turbulent combustion with different viscous models in this study. Premixed C equation values very similar experimental data. Later different excess air ratio values (1.0, 1.1, 1.2 and 1.3) were tested for Methane (100% CH4) and 2000 rpm. The results indicate that increase in excess air ratio have significant effects on in-cylinder pressure, temperature, turbulent flame speed. The turbulent flame speed and flame temperature of CH4/air decreased with increasing EAR.
