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.Hemispherical cylinder head of a spark-ignition internal combustion engine, characterized in that the curved intake manifold has a concavity facing the piston and opens obliquely into the combustion chamber in the vicinity of a spark plug channel inclined in the opposite direction, the axis forms an obtuse angle with that of the intake valve, so that the fuel particles concentrated by inertia along the concave wall of the intake manifold constitute a rich mixture directed preferentially into the candle channel.
