Abstract of the disclosure A control circuit for delivering control signals to interrupt admission of the fuel-air mixture in the low speed and idle circuit of the carburettor of an internal combustion engine. The control circuit is operated according to the engine operating condition. The control signal is delivered in response to compa- rison of a signal whose level is representative of the amplitude of the variations, i.e., the absolute value of the variations in the duration of an engine cycle, with a substantially periodic signal to generate a pulse-shaped signal. The pulses have a relatively narrow width when the amplitude of the variations is great, and a larger width when the amplitude of the variations is smaller.
