ABSTRACT:
A control system for an internal combustion engine of a vehicle equipped with an automatic transmission, comprises a first device for detecting an operating parameter in relation to vehicle cruising, a second device for detecting an engine temperature, and a third device for lowering engine speed at the fully closed position of a throttle valve in response to the detected operating parameter and the detected engine temperature, thereby effectively reducing fuel consumption and engine noise without deterioration in engine running stability.
