How hydrogen combustion engines work, versus gasoline engines. Hydrogen combustion engines can be more efficient and with better emissions versus gas engines, due to the fuel differences of H2.

This video will look at eight major differences between gasoline and hydrogen fuels used in internal combustion engines. This includes the combustion reaction and byproducts, air fuel ratio, ignition energy, flame velocity, autoignition temperature, diffusivity, quenching distance, and density. These properties result in drastic differences between using the two fuels, though both can easily be adopted and used in traditional ottocycle piston cylinder engines, often with little modification to the existing engine hardware. Are hydrogen engines the future of internal combustion? Let's find out!
