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.
Abstract (fr)
Il est proposé un circuit servant, dans des systèmes d'allumage pour moteurs à combustion interne, à la mesure de la tension d'amorçage, transformée du côté primaire d'une bobine d'allumage, sur la bougie d'allumage. Le circuit comporte un transformateur de tension (8) dont le système commandé est déclenché par la tension d'amorçage transformée du côté primaire (2), de manière à générer un courant pouvant être amené à un organe de mesure et proportionnel à la tension d'amorçage.
