Title (DE) ZÜNDANLAGE FÜR BRENNKRAFTMASCHINEN
(EN) IGNITION SYSTEM FOR INTERNAL-COMBUSTION ENGINES
(FR) SYSTEME D'ALLUMAGE POUR MOTEURS A COMBUSTION INTERNE
Abstract:
(DE) Es wird eine Schaltungsanordnung vorgeschlagen, die in Zündanlagen für Brennkraftmaschinen zur Erfassung der auf die Primärseite einer Zündspule transformierten Brennspannung an der Zündkerze dient. Die Schaltungsanordnung umfaßt einen Spannungswandler (8), dessen Steuerstrecke von der auf die Primärseite (2) transformierten Brennspannung derart angesteuert wird, daß ein Strom erzeugt wird, der einem Meßglied zugeführt werden kann und proportional der Brennspannung ist.
(EN) 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.
(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.
