Abstract

Sparks are generated in the ignition distributor of an internal combustion engine during the interruption of the high voltage current which lead to the formation of ozone. In order to remove this ozone causing strong oxidation and corrosion, rapidly out of the ignition distributor, the distributor housing is connected to the charging air line leading from the turbocharger to the cylinder head of the internal combustion engine and is scavenged by charging air.
