An internal combustion engine with externally supplied ignition is proposed, in which besides a main combustion chamber an ignition chamber is provided, which communicates with the main combustion chamber via a central discharge channel, which is disposed coaxially with the axis of the ignition chamber, and via additional discharge channels distributed about this discharge channel. Protruding into the coaxially disposed overflow channel is an electrode extending through the ignition chamber, this electrode being embodied as a heat pipe and forming a spark gap with the wall of the ignition chamber in the region of the overflow channel. As a result of its embodiment as a heat pipe, the electrode is protected against excessive heating and is simultaneously held to an optimal temperature.
