Abstract

Un moteur thermique (MT) comprend un conduit d’admission (CA) comprenant une extrémité (EA) munie d’un siège de soupape (SS) ayant un passage interne (PI) dans lequel se translate une soupape d’admission, et une chambre de combustion (CC) alimentée en air issu du conduit d’admission (CA) via le siège de soupape (SS). Ce passage interne (PI) a une partie amont (PA) recevant l’air du conduit d’admission (CA) et comprenant un extrado (EP) ayant une forme prolongeant de façon continue une portion d’une face interne du conduit d’admission (CA) en direction de la face interne de la chambre de combustion (CC) qui définit son toit (TC), et un intrado (IP) ayant une forme contraignant une partie de l’air à circuler en tourbillon autour d’un axe prédéfini dans la chambre de combustion (CC).
