Abstract (en)
1. A two-stroke internal combustion engine with direct fuel injection wherein the cylinder casing comprises at least one cylinder (4) into which open air intake ducts (7) which are controlled by the associated piston, and at least two casing halves (1A-1B) which are fitted together at a plane which is perpendicular to the axis of said cylinder (4), passing through said ducts, which are oriented inplanes parallel to the axis of the cylinder (4), characterised in that the two casing halves (1A-1B) define an air casing (8) which extends around the cylinder (4) over at least a portion of its periphery, on the one hand, and said two casing halves (1A-1B) are produced in rough cast form by pressure casting on the other hand.

Ce moteur comporte un carter-cylindre (1) pourvu d'un cylindre (4) dans lequel débouchent des canaux (7) d'admission d'air qui sont alternativement masqués et découverts par le piston (5). Le carter-cylindre (1) est constitué de deux demi-carters (1A, 1B) coulés sous pression et assemblés suivant un plan perpendiculaire à l'axe du cylindre (4) et passant par les canaux (7). Le moteur est pourvu d'une chemise mince (10) présentant, au droit des canaux (7), des lumières (12) découvrant chacune l'ouverture de plusieurs canaux. Application aux véhicules automobiles.
