Description

Betriebsverfahren für luftverdichtende Einspritzbrennkraftmaschinen Die Erfindung betrifft ein Betriebsverfahren für luftverdichtende Einspritzbrennkraftmaschiinen. Bei geringer Belastung arbeiten derartige Maschinen meist mit einem. Überschuß an Verbrennungsluft, so daß sich der Verbrennungsvorgang im Bereich niedrigerer Temperaturen abspielt als bei Vollast. Sinkt hierbei die Temperatur unter ein bestimmtes Maß, so werden im Brennraum etwa vorhandene Schmierölteilchen nicht mehr verdampft oder verbrannt. Außerdem bilden. sich Rückstände bei Verivendung solcher Kraftstoffe, deren restlose Verbrennung bei Unterschreiten einer bestimmten Mindesttemperatur nicht mehr gewährleistet ist. In beiden Fällen hat die Unterschreitung einer bestimmten Verbrennungstemperatur offensichtlich eine Verschmutzung des Brennraumes und der Abgasleitung zur Folge.Operating method for air-compressing injection internal combustion engines The invention relates to an operating method for air-compressing injection internal combustion engines. When the load is low, such machines usually work with one. Excess of Combustion air, so that the combustion process in the range of lower temperatures than at full load. If the temperature falls below a certain level, this means that any lubricating oil particles that may be present in the combustion chamber are no longer evaporated or burned. Also educate. there are residues when using such fuels, their complete combustion when falling below a certain minimum temperature is no longer guaranteed. In both cases, the fall below a certain Combustion temperature obviously a contamination of the combustion chamber and the Exhaust pipe result.

Erfindungsgemäß rwr rd eine solche Verschmutzung dadurch vermieden, daß die Verbrennungsluftzufuhr zur Maschine in Abhängigkeit von der Abgastemperatur in der Weise geregelt wird, daß bei jeder Belastungsstufe der der Maschine zur Verfügung stehende Überschuß an Verbrennungsluft so bemessen ist, daß die Abgastemperatur einen bestimmten Wert nicht unterschreitet. Die einzuhaltende Mindesttemperatur richtet sich außer nach. den Eigenschaften des Schmieröles und des Kraftstoffes auch nach den Betriebsbedingungen, unter denen die Maschine jeweils arbeitet und kann durch Versuche leicht ermittelt werden. Die praktische Durchführung der Erfindung kann beispielsweise in der Weise vorgenommen werden, daß eine in die Zufuh-rIeitung für die Verbrennungsluft eingebaute Drosselklappe durch' einen von der Abgastemperatur gesteuerten Thermostaten betätigt wird.According to the invention, such pollution is avoided by that the combustion air supply to the machine depends on the exhaust gas temperature it is regulated in such a way that the machine is available at every load level standing excess of combustion air is dimensioned so that the exhaust gas temperature does not fall below a certain value. The minimum temperature to be observed depends except after. the Properties of the lubricating oil and the Fuel also according to the operating conditions under which the machine is used works and can easily be determined through experiments. The practical implementation the invention can for example be made in such a way that one in the Supply line for the combustion air built-in throttle valve through one of the flue gas temperature controlled thermostat is operated.
