Abstract
L'invention concerne un moteur à combustion interne à deux temps notamment du type Diesel. Ce moteur comporte au moins une soupape d'admission 10 ayant son siège disposé dans la paroi d'une préchambre 13 de combustion et de balayage, et au moins une soupape d'échappement 7, caractérisé en ce que la préchambre 13 communique avec le cylindre par un canal de transfert 14 dont les parois sont en moins en partie sensiblement parallèles à l'axe du cylindre et dont la section droite perpendiculaire à cet axe débouche selon une forme sensiblement oblongue tangentiellement au cylindre. On obtient une meilleure efficacité du moteur. (CF DESSIN DANS BOPI)
