An engine of the opposed piston, two-stroke, compression ignition type includes provision for injection of a main charge of liquid fuel into the bore of a cylinder between opposed pistons early in a compression stroke to permit the fuel to evaporate and mix with air during the remainder of the compression stroke to the point where the stoichiometric components of the mixture are insufficient for autoignition. Further provision is made for injection of a pilot charge of liquid fuel into the compressed air/fuel mixture later in the compression stroke. The pilot charge provides a stoichiometric component which autoignites, thereby activating ignition of the compressed air/fuel mixture.
L~invention concerne un moteur du type à pistons opposés, à deux temps et à allumage par compression, comportant un moyen d~injection d~une charge principale de carburant liquide dans l~alésage d~un cylindre entre des pistons opposés au début d~une course de compression afin de permettre au carburant de s~évaporer et de se mélanger à l~air pendant le reste de la course de compression jusqu~à ce que les composants stoechiométriques du mélange soient insuffisants pour permettre un allumage spontané. Le moteur comporte également un moyen d~injection d~une charge pilote de carburant liquide dans le mélange air/carburant comprimé ultérieurement dans la course de compression. La charge pilote fournit un composant stoechiométrique qui s~allume de façon spontanée, en provoquant ainsi l~allumage du mélange air/carburant comprimé.
