ABSTRACT:
To reliably provide ignition energy only to specific spark plugs (11, 12; 14, 15) of a multi-cylinder internal combustion engine (ICE), a double-E core has a main or common or central branch, and separate primary (6, 8) and secondary windings (10, 13) located in shunt core branches (18', 19'), each secondary winding being associated with respective spark plugs. The magnetic circuits of the primary windings including the common branch and single air gaps (20, 21), each in the shunt magnetic paths (18, 19), so that the flux change generated upon interruption of current flow through the respective primary windings need pass through one air gap only for the associated concentric secondary, buth through two magnetically serially placed air gaps for the other secondary.
