Abstract: An internal combustion engine (10) utilizes, as a fuel, ammonia and gasoline (combustion-supporting fuel) for promoting combustion of ammonia. Ammonia is injected from an ammonia injector (22) into an intake pipe (20), and gasoline is injected from a gasoline injector (24) into the intake pipe (20). An electronic control unit (40) for control of driving of the ammonia injector (22) and the gasoline injector (24) changes the distribution of injection of ammonia and combustion-supporting fuel according to the change of any one or both of the rotation speed and the load of the internal combustion engine (10).

Abstract: An internal combustion engine uses, as the fuel, ammonia and gasoline (supporting fuel) for promoting the combustion of the ammonia. The ammonia is injected from an ammonia injector into an intake pipe, and the gasoline is injected from a gasoline injector into the intake pipe. An electronic control unit for drivingly controlling the ammonia injector and the gasoline injector stops the injection of the ammonia from the ammonia injector and allows the injection of the gasoline from the gasoline injector when the temperature of a cooling water of the internal combustion engine detected by a cooling water temperature sensor is equal to or lower than a predetermined temperature.
