ABSTRACT:
Method for driving an electromagnetic actuator in a diaphragm carburettor for control of air/fuel ratio foresees at least the following steps:associating an electromagnetic actuator in a diaphragm carburettor for control of air/fuel ratio with the current generation device in an internal combustion engine;driving the aforementioned electromagnetic actuator with pulses suitable for generating the force necessary to actuate the actuator;generating said drive pulses of the actuator in the moments when the current pulses of the aforementioned current generator are such that the maximum current is available during the cycle of the motor.
