Abstract
An idling circuit for a carburation device comprises an idling duct for supplying a primary air-fuel mixture downstream of the throttle and a fueled-air line having an adjustable cross-section for circulating an additional quantity of air and primary mixture from upstream to downstream of the throttle. A solenoid valve is energized by pulses having a duty cycle which is controlled so as to keep the engine speed near a set idling speed and so as to increase the amount of mixture supplied to the engine during deceleration at high speed.
