•Délai d’ouverture
An opening delay offset is used to compensate the opening delay
difference between an individual injector and the reference injector.

DENOMINATION SOFTWARE
La dénomination est exprimée sur 8 caractères X1X2X3X4X5X6X7X8 :
- X1 = G représente la plate-forme hardware TRW 32 bits MPC555
- X2 = 6 représente l ’équipe en charge du projet : EAP PSA
- X3 = C pour DV6 PSA et D pour DV6 FORD
- X4/5 = 10, 20, 30 : évolution software sur 2 digits
- X6/7/8 = lettre + 2 digits : gestion de la calibration. PSA et FORD
gèrent leurs calibrations spécifiques

SYNCHRONISATION
•Le but de la synchronisation est d’identifier le cylindre au PMH compression
•L'APS a pour entrée les signaux de la roue crank (60 – 2 dents), et de la roue cam
symetrique à 3 dents.
• La cam tourne 2 fois moins vite que la roue crank.

ETAPES DE SYNCHRONISATION
La stratégie de synchronisation "classique" se découpe en 3 étapes :
1. Détection du gap (zone 2 dents manquantes)
2. Validation des événements CAM de la première révolution crank
3. Validation les événements CAM de la seconde révolution crank
Lorsque ces 3 étapes sont effectuées sans problème,
le label P_L_APS_sync_task_enable est positionné à 1

CONDITIONS DE DEMARRAGE
Le système possède 5 conditions pour injecter :
1) présence clé (+APC) et alimentation
2) régime moteur > seuil (SMC_engine_state = SMC_CRANKING)
3)moteur synchronisé (P_L_sync_task_enable = 1)
4) absence de demande d’arrêt moteur logiciel (SMC_Engine_stop_request = 0)
5) la pression gazoil doit être supérieure à un seuil
(IN_rail_pressure_feedback>I_C_railP_mini_to_inject_APV)
