Title (DE) SCHALTUNG ZUR ZÜNDKERZENSIMULATION
(EN) SPARK-PLUG SIMULATOR
(FR) CIRCUIT POUR LA SIMULATION D'UNE BOUGIE D'ALLUMAGE
Abstract:
(DE) Es wird eine Schaltungsanordnung vorgeschlagen, die zur Simulation des elektrischen Verhaltens einer Zündkerze dient. Die Schaltung umfaßt eine Reihenschaltung aus mindestens einem Widerstand (8) und zwei antiparallel geschalteten Kippdioden (6 und 7), wobei die Kippdioden (6 und 7) ähnlich einer Zündkerze bei Erreichen einer bestimmten Hochspannung durchbrechen und der Spannungsabfall über den Widerstand (8) der Brennspannung einer Zündkerze entspricht.
(EN) Proposed is a device designed to simulate the electrical behaviour of a spark plug. The device includes a series-connected circuit comprising at least one resistor (8) and two four-layer diodes (6, 7) connected in antiparallel arrangement. When a given high voltage is reached, breakover of the four-layer diodes (6, 7) occurs in the same way as in a spark plug, the voltage drop across the resistance corresponding to the sparking voltage of spark plug.
(FR) Il est proposé un circuit servant à la simulation du comportement électrique d'une bougie d'allumage. Ledit circuit comporte un circuit en série composé d'au moins une résistance (8) et de deux diodes à quatre couches montées antiparallèles (6 et 7), les deux diodes à quatre couches (6 et 7) passant à l'état conducteur de manière analogue à une bougie d'allumage lorsqu'une certaine haute tension a été atteinte, la chute de tension par l'intermédiaire de la résistance (8) correspondant à la tension d'amorçage d'une bougie d'allumage.
