Abstract
Description
Die vorliegende Erfindung betrifft eine Zündvorrichtung für Verbrennungskraftmaschinen sowie ein Verfahren zur Durchführung von Ionisationsmessungen an Verbrennungskraftmaschinen.The The present invention relates to an ignition device for internal combustion engines and a method of implementation of ionization measurements on internal combustion engines.
Mit Hilfe von Ionisationsmessungen im Brennraum von Verbrennungskraftmaschinen lassen sich detaillierte Aussagen über charakteristische Größen des Verbrennungsprozesses ableiten. Dies sind u. a. die Luftzahl der Verbrennung, der Brennbeginn, der Druckverlauf während der Verbrennung, die verschleppte Zündung, das Klopfen, Zündaussetzer o. dgl.With Help of ionization measurements in the combustion chamber of internal combustion engines can be detailed statements about characteristic sizes of Derive combustion process. These are u. a. the air ratio of Combustion, the start of combustion, the course of pressure during combustion, the delayed Ignition, the knock, misfire o. like.
Hierzu wird ein Sensorelement üblicherweise an einer repräsentativen Position im Brennraum angeordnet. Typischerweise handelt es sich hierbei um ein elektrisch leitfähiges Element, welches mit Hilfe eines Isolators gegenüber dem Potential des Brennraums isoliert ist.For this becomes a sensor element usually at a representative Position arranged in the combustion chamber. Typically this is this is an electrically conductive Element, which with the help of an insulator against the potential of the combustion chamber is isolated.
Über eine Signalleitung wird eine Messspannung angelegt, und in Abhängigkeit des Verbrennungsverlaufes fließt ein Strom durch die ionisierten Verbrennungsgase vom Sensorelement zur Brennraummasse. Ein derartiger Strom wird nachfolgend ausgewertet.Over a Signal line is applied a measuring voltage, and in dependence the combustion process flows a current through the ionized combustion gases from the sensor element to the combustion chamber. Such a current is subsequently evaluated.
Ionisationsmessvorrichtungen werden typischerweise in den Zündspannungskreis eines Verbrennungsmotors geschaltet. Der Zündspannungskreis besteht hierbei aus einer Zündspuleneinheit, einer Zündkerze sowie einer elektrischen Verbindung zwischen beiden. Die Zündspuleneinheit kann vorteilhafterweise die Leistungselektronik zum Anschalten der Primärspule an die Energieversorgung zum Auslösen des Zündfunkens enthalten.Ionisationsmessvorrichtungen are typically in the ignition voltage circuit an internal combustion engine switched. The ignition voltage circuit exists here from an ignition coil unit, a spark plug and an electrical connection between the two. The ignition coil unit can advantageously the power electronics to turn on the primary coil to the power supply to trigger the spark.
Dabei wird die Energie zum Durchführen einer Ionisationsmessung entweder bei der Zündung dem Zündkreis entnommen oder wird von einer externen Energiequelle zugeführt. Ein Ionisationsstrom bewirkt einen Spannungsabfall an einem Messwiderstand und wird über eine Messleitung an die den Ionisationsverlauf weiterverarbeitenden und auswertenden Einheiten des Motormanagements weitergeleitet. Ein derartiger Aufbau weist jedoch den Nachteil auf, dass eine zusätzliche Leitung erforderlich ist.there becomes the energy to perform an ionization measurement either taken from the ignition or the ignition circuit supplied from an external power source. An ionization current causes a voltage drop across a measuring resistor and is over a Measuring line to the Ionisationsverlauf further processing and forwarded to evaluating units of engine management. One However, such structure has the disadvantage that an additional Line is required.
Aufgabe der Erfindung ist es, eine Zündeinheit und ein Verfahren zur Durchführung von Ionisationsmessungen an Verbrennungskraftmaschinen vorzusehen, bei der zur Weiterleitung des Ionisationssignals an die den Ionisationsverlauf weiterverarbeitenden und auswertenden Einheiten keine zusätzliche Leitung erforderlich ist.task The invention is an ignition unit and a method of implementation provide ionization measurements on internal combustion engines, at the for forwarding the ionization to the ionization processing and evaluating units no additional Line is required.
Erfindungsmäßig wird die Aufgabe dadurch gelöst, dass für die Weiterleitung des Ionisationssignals an die Auswerteeinheit die selbe Leitung benutzt wird, die das Signal zur Triggerung der Leistungselektronik zum Auslösung des Zündimpulses führt. Das Ionisationssignal wird in der Zündeinheit über entsprechende Mittel mit dem Auslösesignal für die Zündung zusammengeschaltet, so können beide Signale über eine Leitung weitergeleitet werden. In der den Zündimpuls steuernden und das Ionisationssignal weiterverarbeitenden Einheit werden die Signale wieder über entsprechende Mittel getrennt und getrennt voneinander verarbeitet.Inventions become solved the task by that for the forwarding of the ionization signal to the evaluation unit the same wire is used as the signal to trigger the Power electronics for triggering the ignition pulse leads. The Ionization signal is in the ignition via corresponding Means with the trigger signal interconnected for the ignition, so can both signals over a line will be forwarded. In controlling the ignition pulse and the Ionization signal processing unit, the signals are again via appropriate Means separated and processed separately.
