ABSTRACT:
A constant depression carburettor has an auxiliary throttle member associated with a sensor which delivers a signal representative of the position of the auxiliary throttle member. A solenoid valve is actuated by pulses received from a control circuit which receives input signals from sensor. The solenoid valve meters the fuel delivered to the intake passage via a discharge orifice located at the throat of a venturi limited by a swelling of the intake passage and by the throttle.
