Abstract

Improvements in ignition systems for internal combustion engines, of the type provided with an ignition coil that serves to accumulate the ignition energy, the primary winding of which is subdivided into a first partial winding and a second partial winding, making the first in series partial winding the parallel connection of two connection branches, of which the first connection branch contains a first switch and the second connection fault contains the series connection consisting of the second partial winding and a second switch, and where also for the preparing the ignition process, the first switch firstly has a conduction state and goes into a blocking state, since the first partial winding exists in the current so that the ignition energy is sufficient while the second switch is in the conduction state, characterized in that as the ignition instant approaches the first switch has a conduction state again and the second switch has a current blocking state, so that in relation to the primary winding of the ignition coil, at the moment of ignition, only the current flow in the first winding must be interrupted partial by the first switch, while the second partial winding is already without current due to the current blocking state of the second switch.
