Abstract
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.
