PROBLEM TO BE SOLVED: To prevent condensation of steam in hydrogen combustion gas. SOLUTION: Saturation temperature to steam partial pressure in combustion gas is found, and cooling water flow by a cooling water supply device 17 is adjusted for a liner temperature to be higher than the saturation temperature for controlling temperature of an inner wall (cylinder liner) of a cylinder 6. Condensation of steam in hydrogen combustion gas is thus prevented, so that adhesion of condensation water to the inner wall (cylinder liner) of the cylinder 6 is eliminated. Deterioration of performance of a hydrogen engine 1 due to large heat loss, and rupture of oil film at sliding parts (the cylinder liner and a piston ring) of a piston 7 and the cylinder 6 to generate risk of seizure are thus eliminated.
