Abstract

Dans un moteur à combustion interne fonctionnant suivant le cycle à deux temps, à injection directe, comportant un cylindre, une tete de cylindre à une extrémité du cylindre, un piston et une lumière d'admission et une lumière d'échappement dans la paroi du cylindre en des endroits opposés sensiblement diamétralement du cylindre. Une cavité dans la tete du cylindre s'étend en direction généralement diamétrale d'un endroit proche de la paroi du cylindre et opposé à la lumière d'échappement. La cavité a des bords latéraux sensiblement droits dans la direction de son extension et sa longueur est d'environ 0,55 à 0,77 fait le diamètre du cylindre.
