Abstract
Il sistema comprende:un primo sensore (107) che rileva i denti (134) presentati con un intervallo da una puleggia (108) calettata sull'albero motore (111); un secondo sensore (112) che rileva discontinuità (135 e 136) di cui una prima è diversa, presentate da un disco (109) sincrono con l'albero motore ma rotante con una velocità dimezzata; primi mezzi (156) atti, all'avviamento, a calcolare e memorizzare la posizione angolare effettiva fra la puleggia ed il disco; secondi mezzi (152) di calcolo della posizione angolare assoluta dell'albero motore per abilitare dei sistemi ad accensione ed iniezione elettronica; e terzi mezzi (153) che, con il primo sensore in avaria, in base al secondo sensore e al segnale elaborato dai primi mezzi, calcolano una posizione angolare presunta dall'albero motore per abilitare i suddetti sistemi.
