Abstract
A method for igniting lean fuel-air mixtures and an apparatus for performing this method are described, wherein a preferably insertable ignition chamber is provided in the wall of an internal combustion engine, which ignition chamber communicates with the main combustion chamber of the internal combustion engine via a plurality of channels. At least one of the channels serves the purpose of delivering a portion of the fresh mixture entering from the main combustion chamber into the first ignition chamber in a direct stream into the rear portion thereof, remote from the combustion chamber, of the first ignition chamber. The other mixture portion of the fresh mixture charge of the ignition chamber is set into rotating motion in the swirl ignition chamber via channels discharging tangentially, on the combustion chamber side, into this chamber, so that a regulated turbulence is established the axial motion component of which is braked, as it advances in the swirl ignition chamber, by means of the fresh charge flowing back out of the rear first ignition chamber portion. In this manner, a substantial increase is attained in the first ignition capacity of the mixture in the ignition chamber.
