In this paper, Fluent software is used to study the flow behavior of methane and air in a CNG-air mixer. Analyses were carried out on various designs to investigate the effect of engine speed on the λ. The design was optimized for throat size, number and size of the holes at the throat circumference. The prototypes were manufactured based on optimized dimensions that were obtained from CFD analyses. The experiments have been done on the prototypes in order to verify the results obtained from CFD analyses. The results show that the performance of the optimized design was good and the decrease of engine power was about 10% and the pollutants such as CO and HC in the gas mode in comparison with the gasoline mode were decreased 100% and 79% respectively.
