Abstract

The spark plug has a cylindrical main body Ä1Ü of electrically conducting material with a central insulator Ä2Ü into which is set a central electrode Ä3Ü. Projecting from the main body are earth electrodes Ä4,5Ü that are set at different levels. These result in different arcing paths ÄFS1-3Ü being established between the electrodes.
