Abstract
In the fuel supply pipe is mounted a regulating valve and a suction device for the engine mixture air. In the fuel supply pipe (16) is mounted a fuel sensor (22) transmitting a signal proportional to the fuel volume through the pipe. An air sensor (26) cooperates with the air suction device (20) and transmits a signal proportional to the air flow volume. A proportioning device (30) receives both signals and transmits a signal, representing a fuel air ratio. A reference signal for a fuel-air ratio is generated by a device (40-48) according to an optimum engine adjustment for a preset operational state. The reference signal and the output signal of the proportioning device are compared in a differential amplifier (36), generating a differential signal which energises a D/A converter (56) controlling the regulating valve (60), in order to provide coincidence with the reference signal. The amplifier preferably energises a two-way counter (54), whose direction depends on the value of the amplifier output signal.
