ABSTRACT:
A system for controlling speed of an engine for a motor vehicle having an air-conditioner at idling of an automotive engine. The engine has a fuel injection system, a bypass provided around a throttle valve, an auxiliary air valve, and a control unit responsive to the closing of an air-conditioner switch for the air-conditioner for opening the auxiliary air valve, thereby increasing intake air. In response to the closing of the air-conditioner switch the quantity of fuel injected in the engine is temporarily increased, thereby increasing engine speed in accordance with the increase of the intake air.
