Abstract—Motorcycles are the primary means of transport in Vietnam. The number increases year by year, putting pressure on big cities about exhaust pollution and partly depleting traditional fuel sources. Therefore, focusing on finding new energy sources to replace traditional fuels is an urgent issue. CNG gas fuel is an alternative energy source that can solve the above problem. This study demonstrated how to calculate the parameters of a blended CNG fuel delivery system. On that basis, to select equipment, design and manufacture a system to supply bi-fuels, CNG and gasoline. In this study, Ricardo Wave simulation software was also used to test the performance parameters when the engine runs on CNG compared to gasoline. Engine operation results using CNG meet stable working conditions in throttle modes. However, the simulation results also show that the engine, when using CNG, decreases power and torque compared to gasoline. In addition, the fuel consumption rate is reduced too. This means a reduction in fuel costs if the engine uses CNG.
