Abstract

Die Erfindung betrifft eine Schaltungsanordnung zur lonenstrommessung im Verbrennungsraum einer Brennkraftmachine mit einer aus Primär- und Sekundärwicklung bestehenden Zündspule (TR1-4), deren Sekundärwicklung (S1-4) sowohl an eine Zündkerze (ZK1-4), die gleichzeitig als lonenstromsonde dient, angeschlossen ist als auch über deren Niedrigpotentialseite mit einem invertierenden Verstärker (3) zur Erzeugung einer konstanten Meßspannung zur lonenstrommessung verbunden ist. Erfindungsgemäß ist zur Ableitung des während der Brenndauer der Zündkerze fließenden Zündstromes auf das Massepotential der Schaltungsanordnung sowohl ein erster Ableitschaltungszweig (A1) mit einer ersten Halbleiterdiode (D2) als auch ein zweiter, parallel zum invertierenden Verstärker (3) geschalteten Ableitschaltungszweig (A2) mit einer zweiten Halbleiterdiode (D1) vorgesehen.

The invention relates to a circuit arrangement for ion current measurement in the combustion chamber of an internal combustion engine with an ignition coil (TR1-4) consisting of primary and secondary windings, the secondary winding (S1-4) of which is connected to a spark plug (ZK1-4), which also serves as an ion current probe is also connected via its low potential side to an inverting amplifier (3) for generating a constant measuring voltage for ion current measurement. According to the invention, both a first discharge circuit branch (A1) with a first semiconductor diode (D2) and a second discharge circuit branch (A2) connected in parallel with the inverting amplifier (3) are connected to one for diverting the ignition current flowing during the burning time of the spark plug to the ground potential of the circuit arrangement second semiconductor diode (D1) provided.
