CALCULATEUR 32 bits
•
Common rail controller
– Contrôle du phasage et de la quantité de fuel injectée
• le cœur du système LDCR
– Contrôle aussi de nombreuses autres interfaces comme EGR,
pre-post chauffage, S2RE, refroidissement moteur
– Réalise l ’interface avec des fonctions véhicules comme la
climatisation, le tableau de bord, la messagerie CAN
•
Main Features.
– 1 PCB simple face 6 couches FR4
– Connecteur composé de 3 modules faisant partie du boitier
plastique
– Composant monté sous capot pouvant resister aux
températures extrèmes jusqu ’à 85°C.
– microcontrolleur 32 Bit MPC555 avec 448k de mémoire flash
intégrée et flash additionnelle externe de 128k
– E2PROM de 4k
– Début de production fin 2002

PRECONISATIONS / PRECAUTIONS
Blindage :
- Recommandée sur le signal Accéleromètre
- En option sur le CAN
Torsadé :
- Recommandée sur le signal CRANK
- Recommandée sur le signal Accéléromètre
- Recommandée sur la commande Injecteurs
Faisceau Injecteurs :
- L’impédance totale (Faisceau aller/retour et connecteurs) ne doit pas dépasser 200 mohms à 20°C
pour ne pas dégrader la commande électrique et être identique sur tous les Injecteurs
=> Longueur de câble limitée (e.g. 4m pour une section de 0,6 mm2)
=> Calibration Injection sans boîtier d’éclatement et/ou bretelle
- Attention à l’ordre de connection
