Abstract

Die Erfindung betrifft eine Vorrichtung zur Erfassung eines Ionenstromes für eine Brennkraftmaschine, umfassend eine Meßspannungserzeugungseinrichtung, einen mit der Meßspannungserzeugungseinrichtung verbundenen Zündstrombypass und einen mit der Meßspannungserzeugungseinrichtung und dem Zündstrombypass verbundenen Meßsignalkonverter.The invention relates to a device for detecting an ion current for a Internal combustion engine, comprising a measuring voltage generating device, a ignition current bypass connected to the measuring voltage generating device and one with the measuring voltage generating device and the ignition current bypass connected measurement signal converter.

Um ein möglichst fahrzeuggerecht aufbereitetes Ionenstrommeßsignal erzeugen zu können, wird vorgeschlagen, als Meßsignalkonverter einen Strom-/Spannungskonverter zu verwenden, der aus einem Operationsverstärker besteht, dessen negativer Eingang mit der Meßspannungserzeugungseinrichtung, dem Zündstrombypass und über einen Widerstand mit dessen Ausgang, welcher das Meßsignal liefert, verbunden ist und dessen positiver Eingang auf Masse oder auf einem leicht erhöhten Potential liegt.

Figure 00000001
In order to be able to generate an ion current measurement signal that is prepared as vehicle-compatible as possible, it is proposed to use a current / voltage converter as the measurement signal converter, which consists of an operational amplifier, the negative input of which with the measurement voltage generating device, the ignition current bypass and a resistor with its output, which supplies the measurement signal , is connected and its positive input is at ground or at a slightly increased potential.
