Distributor

The distributor is an important component of the car when it comes to the mechanical ignition system. It is the part that is in charge of sending power to the spark plugs and making sure that the firing sequence is precise.

Distributor description

The distributor involves a rotating arm in the inner part of the distributor cap and above the distributor shaft. Usually, the metal part of the rotor comes into contact with high voltage cables through a carbon brush. With the high voltage generated from the ignition coil, an electric current can jump the small gaps between the rotors.

Direct and distributor less ignition

Many modern engines have abandoned the idea of high voltage distributors and coils. Instead, it performs the distribution function in the circuit electronically and applies a low voltage pulse. Both of the systems give a finer level of ignition control by the engine computer. The computer enhances the power output, fuel economy, and emissions.

Common issues with a bad distributor

A faulty distributor can lead to stalling, an engine backfire, and poor engine performance.
