A drive unit for an alternator of a motor vehicle is provided with a driven pulley, which rotates around its own axis, and with a unit for connection of the pulley to a rotary drive shaft for the alternator; the drive unit is also provided with a revolution-multiplier device and a torque-limiter device, which are disposed in series with one another and constitute part of the unit for connection of the pulley to the shaft of the alternator.

The device essentially comprises an auxiliary coil for storing the ignition energy, and a transformer for each spark plug. It is thus possible to prepolarize each transformer in the proper sequence with a current opposite that applied during discharge, whereby a transformer of smaller dimensions can be associated with each spark plug while the performance remains unchanged from that of conventional systems.
