Because of air pollution and dry up of fossil fuel, Hydrogen Fuel is focused on as the alternative fuel of fossil fuel. So we research about Rotary Engine, which has good compatibility with Hydrogen Fuel because of its particular mechanics. In this work, we applied hydrogen to rotary engine with compact size, and several kinds of engine oil were used to improve the driving stability. In addition, we measured the output power and torque of 20cc rotary engine to compare with performance of 20cc hydrogen rotary engine. As a result, the highest torque of 0.27 [N-m] in the 20cc rotary engine was obtained at 4000rpm.
