ABSTRACT:
An auxiliary air control system is disclosed for automatically controlling the air flow to an internal combustion engine during the starting phase of the engine's operational cycle to facilitate clean consistant starts under both hot and cold engine conditions. The system embodies an electrically actuated control providing a predetermined air flow during the cranking and subsequent start of the engine. After the start has been achieved, the engine is permitted to accelerate to a speed determined from the engine's temperature. Thereafter the air flow is reduced in a controlled manner to the normal idle air flow. The system not only facilitates consistent starting of the engine but also substantially reduces the noxious exhaust emissions normally attendant the starting of an internal combustion engine.
