Abstract

Culasse hémisphérique de moteur à explosion à allumage commandé, caractérisée en ce que la tubulure d'admission courbe présente une concavité tournée vers le piston et débouche obliquement dans la chambre de combustion au voisinage d'un canal de bougie incliné en sens opposé dont l'axe forme un angle obtus avec celui de la soupape d'admission, de manière à ce que les particules de carburant concentrées par inertie le long de la paroi concave de la tubulure d'admission constituent un mélange riche dirigé d'une manière préférentielle dans le canal de la bougie.
