Abstract:     Hydrogen, methane, and liquefied petroleum gas (LPG) have the fast flame velocities that could affect to the combustion process of gasoline-gas fuelled engines. This leads to reduce in time loss (due to finite combustion process) and to gain higher combustion efficiency and brake thermal efficiency. Thus, the primary objectives of this paper are to study the effects of addition of H2, CH4, and LPG on performance of a gasoline fuel injection motorcycle engine. The combustion process characteristics is predicted by Vibe 2-Zone model and the Woschni 1987 model is used to measure heat transfer process in AVL Boost software. The simulation process bases on characterizing of the motorcycle engine specification and simulating with using gasoline to demonstrate durability of simulation model. Then, the motorcycle model is evaluated when it use gasoline-gas fuel with different gas concentrations (from about 5%, 10%, 15%, 20% and 25%). The obtained results are used to compare each other’s engine characteristics for each type of added gases.
