A device for ignition of an internal combustion engine is described, having a computer and an ignition output stage. A current flow through the primary side of an ignition coil is controllable by the ignition output stage. Furthermore, an arrangement is provided for measuring current flow through the primary side. A charge starting point is calculated by the computer, at which the ignition output stage begins to control a current flow through the primary side. The ignition is triggered at a preselected current through the primary side. The instant of triggering is acknowledged to the computer, which takes this instant into consideration in a further, subsequent calculation of a charge starting point.

Device for ignition of an internal combustion engine

An inductive ignition apparatus for a combustion engine includes a measurement device for ascertaining the ionization current at the spark plug of each cylinder, and includes for each spark plug an ignition coil device which forms the ignition high voltage, operates on the transformer principle, and has a primary and a secondary winding, and through whose secondary winding the ionization current flows. A switch is provided which short-circuits the primary winding for the duration of the ionization current measurement.

Igniting system with a device for measuring the ion current

An ignition system for internal combustion engines, which have means for detecting the secondary voltage transformed to the primary side of an ignition coil, the signal detected by these means being fed to an evaluation device. The evaluation device determines the damping of the voltage signal after the end of sparking, this damping representing a measure for the magnitude of the shunt resistance on the secondary side.
