An ignition system and method for internal combustion engines with which a reliable triggering of an ignition spark is provided with control of the ignition process over the entire firing duration, wherein an excessive stress on the ignition coil and spark plug is avoided. By detecting the primary current and evaluating it in a control loop, the state of the secondary circuit can be detected reliably. In the case of a disturbance, for example at strongly spent spark plug, the ignition current is immediately readjusted via the control circuit in order to avoid a disruption in spark. This ignition current control thus reacts automatically to sources of defect on the secondary side current. |
