Abstract
Automatic starting fluid injection systems are useful, for example, to aid in the cold-starting of diesel engines. In the subject invention, a microprocessor under software control is used to controllably inject starting fluid into an engine passageway, such as an intake manifold. During engine cranking, the microprocessor delivers an injection signal to a fluid delivery system to effect starting fluid injection into the engine passageway. When the engine starts, a subsequent injection time is calculated based on the sensed engine temperature. The microprocessor continues to deliver the injection signal to the fluid delivery system during the subsequent injection time.
