ABSTRACT:
An injector heating apparatus and method for a vehicle engine having fuel injectors with a solenoid coil in a housing for passing fuel into the engine, including an electrical control unit with a alternate normal engine run mode and an injector heating mode and a temperature sensing switch to signal the electrical control so that the fuel pump and engine starter are deenergized and the injector coils are energized for a timed period so that the injectors can be heated and subsequently the temperature of fuel passed therethrough is increased by heat transfer therefrom during a subsequent start and run mode of operation.
