The invention relates to a hydrogen engine, which comprises a hydrogen supply system, an air intake system, an engine body and an exhaust system. The hydrogen supply system comprises a high-pressure hydrogen gas cylinder, an electromagnetic valve, a one or two stage pressure reducing valve, a flame arrester and a connecting pipe. At the same time, the hydrogen gas rail installation hydrogen pressure and temperature sensor, intake pressure and temperature sensor of the pressure stabilizing chamber is arranged at the front end of the intake manifold, a wide domain oxygen sensor is disposed in the exhaust manifold exhaust system; in front of the intake manifold equipped with an electronic solar term door, the hydrogen pressure and temperature sensor, intake pressure and temperature the sensor, wide domain oxygen sensor transmits the signal to the ECU. This engine uses hydrogen instead of gasoline to become engine fuel. On the basis of not changing the engine body and not increasing the cost of the engine, the CO2 emission is reduced to the maximum extent and the emission level of the engine is improved.
