Abstract

SOUPAPE D'INJECTION DE CARBURANT. LA SOUPAPE COMPREND UNE DOUILLE 16 POUVANT COULISSER DANS LA DIRECTION DE L'AXE ET DISPOSEE ENTRE LE CORPS 2, 3 ET LE POINTEAU 12 DE LA SOUPAPE. LA DOUILLE 16 COMPORTE A L'EXTREMITE INFERIEURE UN PROLONGEMENT 21 COMPORTANT UNE ARETE DE COMMANDE 22 QUI COOPERE AVEC LES ORIFICES CALIBRES 7 DU GICLEUR 3. LORSQUE LE MOTEUR FONCTIONNE A PLEINE CHARGE, LA PRESSION DU CARBURANT SOULEVE SUFFISAMMENT LA DOUILLE 16 POUR QUE TOUS LES ORIFICES LIBERENT LE PASSAGE DU CARBURANT. EN REGIME A CHARGE PARTIELLE, UN FLUIDE SOUS PRESSION BLOQUE LA DOUILLE 16 EN POSITION INFERIEURE A LAQUELLE SON ARETE DE COMMANDE 22 NE LIBERE QUE PARTIELLEMENT CERTAINS DES ORIFICES 7. APPLICATION AUX MOTEURS A INJECTION AFIN D'AMELIORER LA FORMATION DU JET DE CARBURANT EN REGIME A CHARGE PARTIELLE.
