Abstract

CE CARBURATEUR COMPREND UN PASSAGE PRINCIPAL DE COMBUSTIBLE 24 QUI RECOIT LE COMBUSTIBLE DE LA CUVE 18 ET LE DEBITE DANS LE VENTURI 28 A TRAVERS UN GICLEUR PRIMAIRE 20 ET UN GICLEUR SUPPLEMENTAIRE 22. CE DERNIER GICLEUR EST COMMANDE PAR UNE SOUPAPE DE DOSAGE 102, ELLE-MEME COMMANDEE SUIVANT UN CYCLE D'ACTIVITE MODULE EN LARGEUR D'IMPULSION. DANS SES PERIODES D'ACTIVITE, LA SOUPAPE FERME LE GICLEUR 22, LE COMBUSTIBLE PASSE UNIQUEMENT PAR LE GICLEUR PRIMAIRE 20. UNE AIGUILLE 26 REGLE LA SECTION LIBRE DE CET ORIFICE ET FIXE LA LIMITE PAUVRE DU RAPPORT DU MELANGE AIR-COMBUSTIBLE FOURNI PAR LE CARBURATEUR EN POSITION D'OUVERTURE PARTIELLE DU PAPILLON 16 DE L'ACCELERATEUR. LA LIMITE RICHE DE CE RAPPORT EST FIXEE PAR LE REGLAGE DE L'AIGUILLE 122 QUI LIMITE LE DEBIT POUVANT PASSER DU GICLEUR 22 AU PASSAGE 24.THIS CARBURETOR INCLUDES A MAIN FUEL PASS 24 WHICH RECEIVES THE FUEL FROM TANK 18 AND THE FLOW IN VENTURI 28 THROUGH A PRIMARY NOZZLE 20 AND AN ADDITIONAL NOZZLE 22. THIS LAST NOZZLE IS CONTROLLED BY AN ELP- DOSING VALVE 102, SAME ORDERED FOLLOWING A MODULE ACTIVITY CYCLE IN PULSE WIDTH. IN ITS PERIODS OF ACTIVITY, THE VALVE CLOSES THE JET 22, THE FUEL PASSES ONLY THROUGH THE PRIMARY JET 20. A NEEDLE 26 REGULATES THE FREE SECTION OF THIS ORIFICE AND SETS THE POOR LIMIT OF THE RATIO OF THE AIR-FUEL MIXTURE SUPPLIED BY THE FUEL IN THE PARTIALLY OPEN POSITION OF THROTTLE 16 OF THE ACCELERATOR. THE RICH LIMIT OF THIS RATIO IS SET BY THE ADJUSTMENT OF THE NEEDLE 122 WHICH LIMITS THE FLOW THAT CAN GO FROM JET 22 TO PASS 24.
