ABSTRACT:
A hydrogen-fueled engine has an intake valve, a hydrogen supply valve and an exhaust valve, which are operated to open and close relative to a combustion chamber, and a control valve provided in a hydrogen supply pipe to control the output of the engine through the control of the flow amount of hydrogen. This control valve is a pressure control valve to adjust the pressure of hydrogen to be supplied. The hydrogen supply valve is operated by an apparatus of the type capable of adjusting the lift and the valve timing. In this engine, the hydrogen to be supplied to the combustion chamber is controlled on the basis of control signals corresponding to load conditions by both the pressure control valve and the hydrogen supply valve under at least one of either the low-load condition or the high-load condition, and substantially only by the pressure control valve under an intermediate-load condition.
