Distributor: Description and Operation

Distributor





The distributor has a centrifugal control and a vacuum control.

The centrifugal control regulates the timing in relation to the engine speed, and the vacuum control regulates it in relation to the engine load.

On Turbo engines, the distributor has a double acting vacuum timing control. The additional function operates when the turbocharger is boosting the intake air pressure.

The timing is then retarded to prevent knocking.
