International ClassesF02P 015/10F02P 003/045 F02P 009/00 Foreign Application Priority Data1992-08-08 DEAbstractAn ignition system for internal combustion engines with sequential spark ignition is provided which serves to ensure that the last individual spark (EZ) of a sequential spark ignition does not lead to damage to the internal combustion engine, for instance damage caused by ignition during the exhaust stroke. A closing time corresponding to a charging process (AL) for an individual ignition is subtracted from a distribution limit (VG) to obtain a calculated limit (11). Once this limit is reached, the current charging process proceeds unimpeded to trigger the individual ignition, but no new charging process will be started. | |
