How does a fuel distributor work?
The fuel distributor is mounted atop a control vane through which all intake air must pass, and the system works by varying fuel volume supplied to the injectors based on the angle of a moving vane in the air flow meter, which in turn is determined by the volume of air passing the vane, and by the control pressure.
What is a fuel distributor?
A Motor Fuel Distributor is someone who acquires motor fuel from a licensed supplier, permissive supplier, or from another licensed distributor for subsequent sale or use.
How does the ECM control the fuel injection amount?
The ECU determines the amount of fuel to inject based on a number of sensor readings. Oxygen sensors tell the ECU whether the engine is running rich (too much fuel or too little oxygen) or running lean (too much oxygen or too little fuel) as compared to ideal conditions (known as stoichiometric).
What does a distributor in a car do?
A distributor is an enclosed rotating switch used in spark-ignition internal combustion engines that have mechanically timed ignition. The distributor’s main function is to route high voltage current from the ignition coil to the spark plugs in the correct firing order, and for the correct amount of time.

What controls the fuel injection system?
The amount of fuel injected is controlled by a flap valve located in the engine’s air intake. The flap sits beneath the control unit and rises and falls in response to airflow – as you open the throttle, the ‘suck’ from the cylinders increases the airflow and the flap rises.
How do I know if my distributor is working?
Place the metal screwdriver near the electrode of the distributor. It should not touch the electrode. Step away from the hood and have someone watch the arc while the ignition is turned on. If there is an arc, it is firing.
How do I know if I have a bad distributor?
A bad distributor produces a unique squealing noise that can be easily distinguished from other engine noises. If you hear such a sound from the engine bay, check under the distributor cap. Generally, a distributor will produce a squealing noise when it’s caked with grease and other pollutants.
