Spark Plug: Description and Operation

GF15.10-P-2000BK Spark Plugs, Description Of Components







Location
Two spark plugs per cylinder are fitted in the cylinder head

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 ignition coils to the spark plugs and causes arcing in the air gap between the central electrode and ground electrode.

All spark plug characteristics are defined in the model formula for the specific manufacturer (e.g. heat rating, seat shape, thread, width across flats, electrode material, spark location).
