Abstract

LA PRESENTE INVENTION SE RAPPORTE AUX DISPOSITIFS DE REGLAGE DE L'AVANCE A L'INJECTION D'UN MOTEUR A COMBUSTION INTERNE DONT LE CIRCUIT DE COMBUSTIBLE COMPREND DES INJECTEURS INDIVIDUELS. L'INJECTEUR AFFECTE A CHAQUE CHAMBRE DE COMBUSTION DU MOTEUR EST ACTIONNE PAR UN MECANISME COMPRENANT UNE CAME, UNE CONTRE-CAME OSCILLANTE 61, 62 QUI ROULE SUR UNE CAME 53 ET UNE TRINGLERIE 27, 27 QUI RELIE LA CONTRE-CAME A L'INJECTEUR. POUR REGLER L'AVANCE, ON DEPLACE LE POINT DE PIVOTEMENT DE LA CONTRE-CAME 61, 62 ET LA POSITION ANGULAIRE DU POINT DE CONTACT ENTRE LA CONTRE-CAME ET LA CAME. LES POSITIONS RELATIVES DE LA CAME, LA CONTRE-CAME ET LA TRINGLERIE SONT TELLES QUE LE DEPLACEMENT DE LA TRINGLERIE NE MODIFIE PAS DE FACON PERCEPTIBLE LA COURSE EFFECTIVE DU PLONGEUR 31 DE L'INJECTEUR PENDANT LE REGLAGE DE L'AVANCE SUR UNE LARGE PLAGE. DE CETTE FACON L'EFFORT DE COMPRESSION EXERCE SUR LE PLONGEUR ET SUR LA BUSE DE L'INJECTEUR AU MOMENT DE L'INTERRUPTION DE L'INJECTION RESTE A PEU PRES CONSTANT QUELLES QUE SOIENT LES VARIATIONS DE L'AVANCE A L'INJECTION.
