Abstract

Ignition device for igniting fuel / air mixtures in a combustion chamber of an internal combustion chamber by a corona discharge. The device includes an ignition electrode and an outer conductor surrounding the ignition electrode. The outer conductor has a front end and a rear end, and comprises an electrical insulator arranged between the ignition electrode and the outer conductor, from which insulator at least one tip of the ignition electrode protrudes. The at least one tip of the ignition electrode is arranged in a space that is shielded by a cap associated with the insulator, said cap having an inner side facing the insulator and an outer side facing away from the insulator as well as one or more holes, by means of which the shielded space is connected to a space arranged on the outer side of the cap.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to a design scheme and structural features of a corona ignition device. Background technique [0002] The invention is based on an ignition device as known from DE 10 2010 045 170 B3 having the features specified in the preamble of claim 1 . Ignition devices of this type are known as corona ignition devices or HF ignition devices. [0003] DE 10 2010 045 170 B3 discloses how a fuel / air mixture in a combustion chamber of an internal combustion engine can be ignited by a corona discharge generated by the internal combustion chamber. To this end, the ignition electrode penetrates electrically insulated through the wall of the internal combustion chamber at ground potential and protrudes into this combustion chamber, preferably opposite a reciprocating piston provided in the combustion chamber. The ignition electrode together with the wall of the combus...
