Abstract

The exhaust emission control monitors the O2 content of the engine exhaust gases, together with the engine load, to regulate the fuel gas/air ratio fed to the engine. The combustion quality of the fuel gas is represented by a measured value and used to correct the fuel gas/air ratio. Pref. the combustion quality is determined from the vol. and mass of given components of the fuel gas, all the measured values fed to an electronic regulator for determining the fuel gas/air ratio.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Betrieb von funkengezündeten oder zündstrahlgezündeten Gasmotoren, insbesondere nach dem Oberbegriff der Ansprü­ che 1 und 4.The invention relates to a method and a device for the operation of spark ignited or spark ignited Gas engines, especially according to the preamble of the claims che 1 and 4.

Handelsübliche Gasmotoren (siehe Dietrich, Grundmann, Langeloth: "Schadstoffminderung stationärer Otto-Gasmoto­ ren der Motoren-Werke Mannheim AG nach dem Magerkonzept", MTZ 47 (1988)/3, und Dietrich, Langeloth: "Die Schadstoff­ minderung stationärer MWM-Otto-Gasmotoren mit dem Dreiweg­ katalysator-Konzept", MTZ 45 (1984)/12) arbeiten zum Er­ reichen der vorgeschriebenen Abgasqualität entweder mit stöchiometrischem Brenngas-Luftgemisch und nachgeschalte­ tem Dreiwegkatalysator, oder mit magerem Brenngas-Luftge­ misch ohne katalytische Nachbehandlung, ggfs. jedoch mit Oxidations-Katalysator.Commercial gas engines (see Dietrich, Grundmann, Langeloth: "Pollution reduction of stationary Otto gas engines ren of Motoren-Werke Mannheim AG according to the lean concept ", MTZ 47 (1988) / 3, and Dietrich, Langeloth: "The pollutant reduction of stationary MWM Otto gas engines with the three-way catalyst concept ", MTZ 45 (1984) / 12) work on the Er range with the prescribed exhaust gas quality either stoichiometric fuel gas-air mixture and downstream three-way catalytic converter, or with lean fuel gas air mixed without catalytic aftertreatment, but possibly with Oxidation catalyst.

Das Magerkonzept ist wegen des fehlenden Katalysators be­ sonders bei Verwendung von Deponiegas von Vorteil, da die in diesem Gas möglicherweise vorhandenen Schadstoffe einen Abgaskatalysator unwirksam machen können. The lean concept is due to the lack of catalyst Particularly advantageous when using landfill gas, since the any pollutants present in this gas Can make the catalytic converter ineffective.  

Eine Schwierigkeit liegt bei dem Magerkonzept darin, daß bei Schwankungen der Gasqualität in Richtung mager oder fett, wie sie insbesondere bei Deponiegasen üblich sind, sich der Luftbedarf des Gases ändert und daher die Grenzen der Schadstoffemission bzw. die Aussetzer- oder Klopfgren­ ze überschritten wird.One difficulty with the lean concept is that if the gas quality fluctuates towards lean or bold, as is common with landfill gases, the air requirement of the gas changes and therefore the limits the pollutant emission or the misfire or knocking ze is exceeded.

Der Erfindung liegt die Aufgabe zugrunde, eine Lösung zur Regelung von funkengezündeten oder zündstrahlgezündeten Gasmotoren zu schaffen, die einen schadstoffarmen und zu­ gleich verbrauchsgünstigen Betrieb gewährleistet.The invention has for its object a solution for Regulation of spark ignited or spark ignited To create gas engines that are low in pollutants and too equally economical operation guaranteed.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnen­ den Merkmale der Ansprüche 1 und 4 gelöst.According to the invention, this object is characterized by the solved the features of claims 1 and 4.

Auf diese Weise gelingt es in vorteilhafter Weise, die ne­ gativen Auswirkungen der Gasqualitätsschwankungen zu ver­ meiden und das für die vorgeschriebene Abgasqualität er­ forderliche Brenngas-Luftverhältnis bzw. der Sauerstoffge­ halt im Abgas und den für geringe Schadstoffemission und zugleich niedrigen Brenngasverbrauch erforderlichen Zünd­ zeitpunkt einzuhalten.In this way it is possible in an advantageous manner, the ne negative effects of gas quality fluctuations avoid and that for the prescribed exhaust gas quality required fuel gas / air ratio or oxygen hold in the exhaust gas and for low pollutant emissions and at the same time low fuel gas consumption required ignition to comply with the point in time.

In einer vorteilhaften Weiterbildung der Erfindung werden die verschiedenen Möglichkeiten zur Erkennung der Brenn­ gasqualität beschrieben, die zum Teil die Aussetzergrenze, zum Teil die Klopfgrenze betreffen. Überlicherweise ist es ausreichend, eine Kenngröße des Gases zu analysieren. Es kann aber auch vorteilhaft sein, zwei oder mehrere Brenn­ gaseigenschaften zu berücksichtigen. In an advantageous development of the invention the different ways of detecting the burning described gas quality, which in some cases is the misfire limit, partly affect the knock limit. Usually it is sufficient to analyze a parameter of the gas. It but can also be advantageous, two or more focal gas properties to take into account.  

Eine vorteilhafte Ausbildung der Erfindung bietet die Mög­ lichkeit, die vielen Meßdaten der unterschiedlichen Meß­ vorrichtungen rasch und genau zu verarbeiten und damit das Brenngas-Luftverhältnis und den Zündzeitpunkt im optimalen Bereich zu halten. Dadurch wird einerseits die Einhaltung der Abgasvorschriften sichergestellt und andererseits eine Schädigung des Motors durch klopfende Verbrennung vermie­ den, eine Gefahr, die insbesondere bei Erdgasbetrieb aus öffentlichen Gasnetzen besteht, wenn zur Spitzenlastab­ deckung Propan-Luft bzw. Butan-Luft zugemischt wird.The Mög offers an advantageous embodiment of the invention the many measurement data of the different measurement to process devices quickly and precisely and thus the The fuel gas-air ratio and the ignition point in the optimal Keep area. On the one hand, this ensures compliance the exhaust gas regulations ensured and on the other hand a Avoid damage to the engine due to knocking combustion the, a danger that particularly arises from natural gas operation public gas networks exist when at peak loads cover propane-air or butane-air is added.

Durch eine erfindungsgemäße Weiterbildung des Reglers wird der Enwicklungsaufwand für die Regelungsanlage niedrig ge­ halten und deren Ausführbarkeit verbessert, da an sich vorhandene Meßeinrichtungen verwendet werden können. Das gilt auch für die vorteilhafte Ausbildung des elektroni­ schen Reglers mittels Mikroprozessors.Through a further development of the controller according to the invention the development effort for the control system is low maintain and their feasibility improved as such existing measuring devices can be used. The also applies to the advantageous training of electronics controller using a microprocessor.
