Location
On each cylinder, a spark plug is inserted from the top of the cylinder head to centrally in the combustion chamber.
Task
The spark plugs ignite the suctioned and compressed fuel-air mixture due to arcing between the electrodes.
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.
All the spark plug characteristics are defined by the type symbols provided by the manufacturer (e.g. heat rating, seat shape, thread, width across flats, electrode material, spark position).
