ABSTRACT:
An electronic engine control is disclosed having an electronic cooling fan control. The cooling fan is turned on or off according to a predetermined strategy and inputs from several engine parameter sensors. By disengaging the cooling fan when it is not needed for engine cooling, the fan control reduces the power that is unnecessarily drawn from the engine to drive the fan.
