The mixture control unit is located between the air filter and the throttle plate assembly and consists of the Air Flow Sensor and the Fuel Distributor.
The air flow sensor measures the amount of air entering the intake manifold and controls the amount of fuel injected by the fuel distributor. This
quantity is modified, to adapt to various operating conditions, by the frequency valve, control pressure regulator, and the oxygen sensor, Fig. 1.
