ABSTRACT:
An ignition chamber device is described which has an elongated, rotationally symmetrical form. The wall of the ignition chamber which protrudes into the main combustion chamber of the internal combustion engine has a coaxial overflow conduit embodied by a nozzle and radially extending discharge conduits which extend into the annular chamber which surrounds the nozzle. The ignition chamber is provided with an ignition device which has a central electrode that leads from the outside into the interior and by means of this central electrode the ignition voltage is carried via a conductor path, disposed in the wall, to a wall location opposite the nozzle, from where the ignition spark can leap the gap. A heat pipe is disposed in the nozzle and includes a portion arranged in close proximity to the cylinder wall, which prevents the ignition chamber from becoming overheated and on the other hand also enables the inflowing mixture to be heated up in optimal fashion on the way to the ignition location.
