Location

In the cylinder head, each cylinder has a spark plug located in the center between the engine valves.

Task

The compressed fuel-air mixture is combusted by sparks between the electrodes according to the actuation from the ME control unit.

Design

In the manufacturer's specific type symbols, all the spark plug features are assigned (e. g. heat rating, shape of seating, thread, width across flats, electrode material, spark position).

Function

The ignition voltage flows from the ignition lines of the directly plugged in ignition coils to the spark plugs and causes arcing in the air gap between the central electrode and ground electrode.
