distributor cap

The distributor cap is a key component of the classic ignition system in gasoline engines with a distributor. It ensures that the high voltage generated by the ignition coil is correctly distributed to the individual spark plugs of the cylinders. This generates the spark at the correct moment in each cylinder.

Inside the distributor cap is the contact area, through which the distributor rotor transmits the high voltage to the individual ignition cables. These are connected to the respective spark plugs. The precise distribution of the ignition voltage is crucial for clean combustion, smooth engine running, and optimal engine performance.

Distributor caps are typically made of heat-resistant plastic or special insulating materials that reliably insulate against high electrical voltages. Inside are metal contacts that ensure a reliable transmission of the ignition voltage. These components must withstand high temperatures, humidity, and electrical stresses in the engine compartment.

In older vehicles with a mechanical distributor, the distributor cap is one of the typical wear parts that should be checked regularly and replaced if necessary to avoid misfires or starting problems.
