Abstract

Il sistema di sincronizzazione di un motore a combustione interna comprende una prima ruota fonica (1) fissata ad un albero motore (2) e dotata di una pluralità di denti (3) distanziati uniformemente ad eccezione di almeno un tratto non dentato (4); una seconda ruota fonica (9) fissata ad un albero della distribuzione (8) e comprendente almeno un dente (10); un primo ed un secondo trasduttore (5, 12) associati alle due ruote foniche. Le uscite dei trasduttori vengono elaborate in modo da ottenere due segnali elettrici (SM, SC) presentanti ciascuno un impulso in corrispondenza del rilevamento di ogni dente della ruota fonica associata. Per rendere più rapido il riconoscimento della fase motore all'avviamento, le due ruote foniche (1, 9) sono posizionate in modo prefissato una rispetto all'altra.Figure 1 e 2.
