Abstract (en)
[origin: WO9210673A1] Proposed is a circuit designed to measure on the spark plug the spark voltage transformed in the primary winding of the ignition coil in the ignition system of an internal-combustion engine. The circuit includes a voltage transformer (8) whose controlled system is triggered by the spark voltage transformed in the primary winding (2) of the ignition coil in such a way that a current is generated which can be fed to a sensor element and is proportional to the spark voltage.
