Abstract (en)
[origin: DE4226248A1] An ignition system for internal combustion engines has a controller (7) for triggering a sequence of spark ignitions which measures the primary current (Ip) of each spark ignition of this sequence of spark ignitions every time the current flow is again switched on and compares it with a reference value. The result of this comparison allows the conditions in the combustion chamber to be ascertained and measures are taken by the controller, in particular an increase in the primary switching off current, so that for example existing shunts may be eliminated.
