Mixture Control Unit

Airflow sensor housing contains sensor plate which moves in cone-shaped venturi. All engine intake air is drawn past sensor plate.

Movement of sensor plate lever changes position of control plunger in fuel distributor. Control plunger is used to meter amount of fuel injected into each cylinder. Movement of plate is controlled by amount of air flowing through airflow sensor housing.

Fuel distribution pressure to each injector is equal. Pressure regulating valves in fuel distributor equalize system pressure. These valves are not adjustable.
