ABSTRACT:
This sparking-plug for an internal combustion engine having a controlled ignition comprises a device for evacuating the heat of the earth electrode, the heat of the center electrode and the heat of the end of the nose of the insulator of the center electrode. This end of the nose of the insulator projects into the combustion chamber of the engine in which it is partly exposed to the flame front of the combustion and partly masked off by said device. The device constitutes a massive support for the earth electrode.
