Therefore, countries of the world dedicated to develop alternative fuels which applying to internal combustion engine, in order to reduce consumption of fossil fuel and emission of greenhouse gas. Hydrogen fuel has been assessed to a well potential solution on internal combustion engine all over the world. Furthermore, as hydrogen fuel is depleted, it is almost zero pollution and has higher thermal efficiency than petrol, diesel and natural gas in internal combustion engine. In this study, we utilized GT-Suite which is simulation software for internal combustion engine to investigate the heat transfer phenomena of direct injection hydrogen engine. The software verified the cylinder pressure, maximum pressure, indicated mean effective pressure, Brake Torque, and mass fraction burned of hydrogen engine. Finally, with the points above, we extended discussion to heat transfer coefficient.
