ABSTRACT:
The present invention relates to a combustion chamber in which two flows of gas are admitted via ports at the bottom of the cylinder, one of the flows being a mixture containing fuel and the other being a flow of pure air. These flows are admitted so that they meet inside the chamber close to the wall opposite from an exhaust port (5) so that the mixture is confined and slowed down in a cavity (9) in the cylinder head while the flow of pure air is split by an edge (12) formed between said cavity and the bottom wall (11) of the cylinder head so that one portion of this air flow returns and scavenges the combustion chamber (1).
