摘要： PROBLEM TO BE SOLVED: To suppress occurrence of pre-ignition of hydrogen in changing over used fuel from gasoline to hydrogen, in a dual fuel engine capable of executing changeover between hydrogen and gasoline. SOLUTION: When the changeover of used fuel from the gasoline to the hydrogen is determined (step S5) and an engine load is high, execution of the changeover of the used fuel from the gasoline to the hydrogen is prohibited until the engine load becomes low.

摘要： PROBLEM TO BE SOLVED: To prevent a fuel in use from being frequently switched when the fuel in use of an engine is switched according to the values related to the operating conditions of a vehicle in the vehicle having the dual-fuel engine in which a gas fuel and a gasoline as the fuel in use is switched with each other. SOLUTION: The next switching of the fuel in use is limited (prohibited) (step S9) until a predetermined time is elapsed from the switching (steps S5, S8) of the fuel in use (step S10).
