Abstract

A throttle valve control apparatus having a valve closing device for closing the throttle valve beyond the idling position thereof. The valve closing device is controlled by a control mechanism which is responsive to engine speed and includes an engine speed sensor. The closing device is operated at the time of deceleration of the engine from the condition that the engine speed is above a predetermined minimum ON speed and is released from operation when the engine speed is lowered to a predetermined OFF speed which is near the idling speed. The ON speed is set to be above an upper-limit of an adjustment error range predetermined about the actual idling speed.
