FUEL SUPPLY DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

A temperature reduction control for reducing the temperature of an injector is performed through first to third fuel supply control routines executed by an electronic control device. When the temperature of the injector is reduced by the execution of the temperature reduction control, heat transfer to the vicinity of the nozzle of the injector is reduced. Since the vicinity of the nozzle of the injector is less likely to be placed in a high-temperature environment by in accordance with reduction in heat transfer to the vicinity of the nozzle of the injector, the formation of deposit around the nozzle of the injector is suppressed.
