  • Publication number: 20080079344
    Abstract: A spark plug for a combustion engine comprises a thermally and electrically conductive metal casing with attachment means, in the cavity of which there is a ceramic insulator with central electrode against which, to create the spark gap of the spark plug, there is arranged a lateral electrode fixed to the casing. According to a method, the mutual positioning of the body of the ceramic insulator and the thermally and electrically conductive casing with a lateral electrode of the spark plug, against the thrust of the body of the ceramic insulator from the cavity in the casing at its outer end, opposite the spark gap, is secured by bending the radial shoulder on the front surface of the casing at its outer end into contact with the outer shoulder of the insulator.
