Abstract
What is described is a corona ignition device for igniting fuel in an internal combustion engine by generating a corona discharge, said corona ignition device comprising a housing, an insulator, which is held in the housing, a center electrode, which is held in the insulator, and at least one ignition tip at an and of the center electrode. The housing surrounds an interior, which has a cylindrical portion in which a cylindrical portion of the insulator sits. A widened interior portion adjoins at the end of the cylindrical interior portion remote from the ignition peak. The insulator has a thinner portion in the widened interior portion. The cylindrical portion of the insulator carries an electrically conductive coating, which ends before the thinner portion.
