Abstract

ENSEMBLE MOTEUR COMPRENANT UN MOTEUR 53 AUQUEL DU CARBURANT EST FOURNI PAR DES UNITES POMPE-INJECTEUR 10 COMMANDEES PAR SOLENOIDE. UNE UNITE D'ALIMENTATION 61 COMMANDEE PAR UN BLOC DE COMMANDE 62 ALIMENTE LES INJECTEURS EN COURANT. LE DEMARREUR 58 EST ALIMENTE PAR UNE BATTERIE 59 PAR L'INTERMEDIAIRE D'UN RELAIS A RETARD 60 QUI AGIT LORSQU'UN INTERRUPTEUR DE DEMARRAGE 64 EST ACTIONNE. LE BLOC DE COMMANDE EST CONCU POUR RETARDER L'ACTIONNEMENT DU DEMARREUR JUSQU'A EXCITATION COMPLETE DES SOLENOIDES DE TOUTES LES UNITES POMPE-INJECTEUR. LORSQUE LA VITESSE DE MISE EN ROUTE DU MOTEUR ATTEINT UNE VALEUR DETERMINEE, LES INJECTEURS FONCTIONNENT A LA MOITIE DE LEUR COURSE, MAIS CHACUN FONCTIONNE AU MOINS DEUX FOIS POUR FOURNIR LA QUANTITE DE CARBURANT REQUISE POUR LE DEMARRAGE. LE RETOUR A UN REGIME DE FONCTIONNEMENT NORMAL N'A LIEU QUE LORSQUE LA TENSION DE LA BATTERIE A ATTEINT UNE VALEUR SUFFISANTE POUR QUE LES UNITES POMPE-INJECTEUR PUISSENT FOURNIR LA QUANTITE DE CARBURANT NECESSAIRE EN UNE SEULE COURSE.
