CONTROLLER OF INTERNAL COMBUSTION ENGINE

摘要

An internal combustion engine (10) uses, as the fuel, ammonia and gasoline (supporting fuel) for promoting the combustion of the ammonia. The ammonia is injected from an ammonia injector (22) into an intake pipe (20), and the gasoline is injected from a gasoline injector (24) into the intake pipe (20). An electronic controller (40) for drivingly controlling the ammonia injector (22) and the gasoline injector (24) stops the injection of the ammonia from the ammonia injector (22) and allows the injection of the gasoline from the gasoline injector (24) when the temperature (Tw) of the cooling water of the internal combustion engine (10) detected by a cooling water temperature sensor (42) is equal to or lower than a predetermined temperature (T0).
