Abstract
A fuel delivery system having an electronically controlled throttle valve operatively disposed in an intake manifold. An idle speed control valve is operatively disposed within a bypass gas flow passageway. A control system controls the actuation of both the throttle valve and idle speed control valve to control the delivery of a combustible charge to the internal combustion engine to maximize engine efficiency and minimize noxious emissions.
