Abstract

MOTEUR A PISTONS, DANS LEQUEL LE COMBUSTIBLE EST INJECTE DANS UNE CHAMBRE DE PRECOMBUSTION COMMUNIQUANT PAR UNE TUYERE TANGENTIELLE AVEC UNE CHAMBRE DE COMBUSTION PRINCIPALE. AU CENTRE DE LA CHAMBRE DE PRECOMBUSTION, EST PREVU UN ELEMENT DEFLECTEUR SOUMIS A L'IMPACT D'AU MOINS UNE FRACTION DE LA CHARGE DE COMBUSTIBLE INJECTEE. LA CHARGE DE COMBUSTIBLE EST INJECTEE PAR L'INJECTEUR 3 AU MOINS PARTIELLEMENT EN UN JET AUXILIAIRE 12 DIRIGE CONTRE L'ELEMENT DEFLECTEUR 9; LE DEBIT IMPARTI A CE JET AUXILIAIRE 12 EST PILOTE DE TELLE SORTE QUE DANS LA PHASE DE DEMARRAGE ET EN CHARGE FAIBLE ETOU AUX BAS REGIMES, AU MOINS UNE PARTIE ESSENTIELLE DE LA CHARGE DE COMBUSTIBLE EST INJECTEE EN JET AUXILIAIRE. APPLICATION NOTAMMENT AUX MOTEURS DIESEL.PISTON ENGINE, IN WHICH THE FUEL IS INJECTED INTO A PRECOMBUSTION CHAMBER COMMUNICATING THROUGH A TANGENTIAL TUBE WITH A MAIN COMBUSTION CHAMBER. AT THE CENTER OF THE PRECOMBUSTION CHAMBER, A DEFLECTOR ELEMENT IS PROVIDED FOR THE IMPACT OF AT LEAST A FRACTION OF THE INJECTED FUEL LOAD. THE FUEL LOAD IS INJECTED BY THE INJECTOR 3 AT LEAST PARTLY IN AN AUXILIARY JET 12 DIRECTED AGAINST THE DEFLECTOR ELEMENT 9; THE FLOW ALLOCATED TO THIS AUXILIARY JET 12 IS PILOT SUCH AS IN THE START-UP PHASE AND LOW LOAD OR LOW SPEEDS, AT LEAST AN ESSENTIAL PART OF THE FUEL LOAD IS INJECTED IN THE AUXILIARY JET. APPLICATION IN PARTICULAR TO DIESEL ENGINES.
