Abstract
Il sistema (1) comprende:un primo blocco (7) che determina una scarica di tipo induttivo fra gli elettrodi di una candela (6) del motore (3);un secondo blocco (8) che determina una scarica di tipo capacitivo fra gli elettrodi della candela (6); una centralina elettronica (2) che riceve dei segnali relativi a grandezze e condizioni di funzionamento del motore (3) per selezionare una scarica fra quelle di tipo induttivo, di tipo capacitivo, e di tipo induttivo più capacitivo e viceversa e per determinare in caso di una scarica combinata lo sfasamento fra le due scariche; ed un terzo blocco (5) abilitato dalla centralina (2) per comandare il primo ed il secondo blocco (7 e 8).The system (1) comprises: a first block (7) which causes an inductive discharge between the electrodes of a spark plug (6) of the motor (3); a second block (8) which causes a capacitive discharge between the spark plug electrodes (6); an electronic control unit (2) which receives signals relating to the quantities and operating conditions of the motor (3) to select a discharge from those of the inductive type, of the capacitive type, and of the more capacitive inductive type and vice versa and to determine in the event of a combined discharge the phase shift between the two discharges; and a third block (5) enabled by the control unit (2) to control the first and second blocks (7 and 8).
