Abstract
Moteur à combustion interne du type à piston comportant au moins un cylindre, caractérisé en ce que le cylindre ou chaque cylindre comportant une chambre principale de combustion, une chambre de pré-combustion caractérisée en ce que la chambre de pré-combustion est divisée en une cavité primaire et une cavité secondaire qui communiquent par l'intermédiaire d'une ouverture et en ce qu'il comporte en outre un dispositif d'allumage par étincelles qui communique avec ladite cavité primaire, un conduit principal d'admission pour distribuer un mélange relativement pauvre d'air et de combustible à ladite chambre principale pendant la course d'admission, un conduit d'admission d'air neuf et une soupape auxiliaire d'admission pour distribuer de l'air neuf à ladite cavité primaire et à ladite cavité secondaire pendant la course d'admission, des moyens comprenant un injecteur de combustible pour distribuer du combustible pendant la cour d'admission pour le mélanger avec l'air neuf afin de former des mélanges relativement riches d'air et de combustible dans les deux cavités, un conduit primaire de flammes relativement long s'étendant de ladite cavité primaire jusqu'à la chambre principale de combustion et agencé pour diriger une flamme vers la zone centrale de ladite chambre principale, et un conduit secondaire de flammes relativement court s'étendant de ladite cavité secondaire jusqu'à la chambre principale de combustion et agencé pour diriger une flamme vers une zone périphérique de ladite chambre principale.
