Abstract
Moteur présentant dans la tête de piston ou dans la culasse une chambre de combustion de révolution, avec une gorge rétrécie, dans laquelle l'air de combustion est mis en rotation autour de l'axe de révolution de la chambre, où, en tenant compte du volume déterminé de la chambre de combustion, le diamètre de la chambre, la profondeur de la chambre, la courbure de la paroi de la chambre et la courbure de la transition de la paroi de la chambre vers le fond de la chambre sont assortis de telle manière entre eux, qu'en utilisant le frottement créé entre la paroi et l'air, on produise un courant de couche-limite qui développe des composantes de vitesse d'une intensité déterminée, verticales ou presque verticales par rapport au mouvement rotatif, ces composantes produisant des tourbillons secondaires.
