PROBLEM TO BE SOLVED: To provide an engine system for driving an engine with hydrogen gas as one of fuels, which controls the supply amount of air and hydrogen rich gas, and is superior in exhausting performance and fuel economy performance. SOLUTION: The engine system is equipped with: a detection means provided in a hydrogen rich gas supply pipe for supplying hydrogen rich gas to a combustion chamber of the engine, for detecting the supply amount or the supply pressure of the hydrogen rich gas; a hydrogen rich gas supply valve control means for controlling the opening/closing timing and the opening/closing lift amount of the hydrogen rich gas supply valve installed in the combustion chamber of the engine, based on the supply amount or the supply pressure detected by the detecting means; an intake valve for supplying air to the combustion chamber of the engine, independent from the hydrogen rich gas supply valve; and an intake valve control means for controlling the air amount sucked into the combustion chamber of the engine by the intake valve.
