Abstract
The hydrogen engine includes a blow-by gas passage that recirculates the blow-by gas leaked from the combustion chamber to the crankcase from the crankcase to the intake passage. The threshold temperature is set in advance based on the temperature at which the water contained in the oil stored in the crankcase starts evaporation in the crankcase. The control device limits the output of the hydrogen engine from when the oil temperature, which is the temperature of the oil, exceeds the threshold temperature for a predetermined period of time.
