Abstract
An internal combustion engine having an ignition chamber communicating with a main combustion chamber via at least one transfer channel, with the ignition chamber forming a closed circular cylinder and its cylindrical wall being protected by an annular thermal pipe from too-rapid cooling and from overheating. In the wall of the ignition chamber, partial electrodes disposed in an insulated manner are provided which are electrically connectable via spark gaps with each other and with the ignition voltage supply line. As a result, ignition occurs near the wall in an area at an elevated temperature level and, in particular, in the immediate vicinity of the entry point of the fresh fuel-air mixture via the overflow channel so that, as a result, the flammability is maintained with increased leaning of the fuel-air mixture.
