Inductive-discharge ignition device for an internal combustion engine.

摘要

The device (1) is of the type comprising for each engine spark plug (2) a transformer (3) with a secondary winding (4) to be connected to the respective spark plug (2) and a primary winding (5) connected to the output of a power stage (6) able to provide an ON-OFF signal for controlling the transformer (3). The device (1) also comprises a damping network (15) and, interposed between the network (15) and the output of the power stage (6), unidirectional connection means (20) which connect said network (15) to the output of the power stage (6) each time the signal present at said output switches from an OFF condition to an ON condition.
