Abstract
Moteur comportant au moins un cylindre, fermé par une culasse munie d'une chambre de combustion et un piston dont la tête est munie d'un bossage déterminant avec la culasse une chambre auxiliaire dans la chambre de combustion; des moyens pour introduire un mélange riche en combustible dans cette chambre auxiliaire; des moyens d'allumage du mélange riche. La chambre de combustion 3 comporte un logement 10 ayant une face ouverte 11 selon une direction transversale par rapport à la direction de déplacement DELTA du piston ; ce logement 10 peut recevoir le bossage 6 du piston pour former la chambre auxiliaire; les moyens d'allumage 8 sont situés sensiblement vers la face ouverte 11, tandis que les moyens 7a pour introduire le mélange riche débouchent du côté éloigné de cette face ouverte 11. Application aux moteurs pour véhicules automobiles.
