Abstract

Die Erfindung betrifft eine Schaltungsanordnung zur lonenstrommessung im Verbrennungsraum einer Brennkraftmaschine mit einer aus Primär- und Sekundärkreis bestehenden Zündspule (TR), die von einem Bordnetz (UB) gespeist wird, und einer im Sekundärkreis angeordneten Zündkerze (ZK), die gleichzeitig als lonenstromsonde dient. Erfindungsgemäß sind Schaltungsmittel vorgesehen, mit denen eine lonenmeßspannung an den Sekundärkreis der Zündspule (TT) abgelegt wird, wobei diese lonenmeßspannung einen Wert aufweist, der dem Wert des Bordnetzes (UB) entspricht oder unter diesem Wert liegt und ferner ein Gleichrichterelement (D1) in den Sekundärkreis geschaltet wird, das den während der Zündung der Zündkerze erzeugten Zündstrom auf das Bordnetz ableitet.

The invention relates to a circuit arrangement for ion current measurement in the combustion chamber of an internal combustion engine with an ignition coil (TR) consisting of primary and secondary circuit, which is fed by an electrical system (UB), and a spark plug (ZK) arranged in the secondary circuit, which also serves as an ion current probe. According to the invention, switching means are provided with which an ion measurement voltage is applied to the secondary circuit of the ignition coil (TT), this ion measurement voltage having a value that corresponds to or is below the value of the vehicle electrical system (UB) and also a rectifier element (D1) in the Secondary circuit is switched, which leads the ignition current generated during the ignition of the spark plug to the electrical system.
