Description

Verfahren zum Betriebe von brennkraftmaschinen Vorliegende Erfindung bezieht sich auf .eine weitere Ausgestaltung der Verfahren zum Betriebe von Brennkraftmaschinen mit Verdichtung der Verbrenniuigsluft und Einführen des Brennstoffes im Totpunkt ;oder kurz vor -oder nach diesem (Dieselprinzip).Method for operating internal combustion engines. Present invention relates to .ein another embodiment of the method for operating internal combustion engines with compression of the combustion air and introduction of the fuel in the dead center ; or shortly before - or after this (diesel principle).

Beim Verwenden leicht siedender Brennstoffe in diesen Maschinen hat es sich herausgestellt, daß die Verbrennung zu rasch verläuft, so daß unerwünschte Druckstöße auftreten.When using low-boiling fuels in these machines it turned out that the combustion proceeds too quickly, so that undesirable Pressure surges occur.

Es ist bereits vorgeschlagen worden, durch den Druck von erzeugtem Dampf oder von ;gespeichertem Verbrennungsgas Dieselöl auf den Einspritzdruck zu bringen und dann beim Einspritzvorgang zu zerstäuben, also. dadurch die Einspritzpumpe zu ersetzen, wobei außerdem durch Wirbelung eine schnellere Verbrennung des Dieselöls erzielt werden soll.It has already been suggested to be generated by printing Steam or from; stored combustion gas diesel oil to the injection pressure bring and then atomize during the injection process, so. thereby the injection pump to replace, in addition, a faster combustion of the diesel oil by swirling should be achieved.

Gemäß der vorliegenden Erfindung wird. dieses bei Dieselöl bekannte Verfahren auf mittlere und leichtere Treibstoffe in der Art angewandt, daß dieser Brennstoff mittels inerten Gases so stark verdünnt wird, daß der Verbrennungsvorgang zeitlich ausgedehnt wird, wobei aber infolge der Zerstäubung und Durchwirbelung beim Einblasen eine vollständige Verbrennung sich ergibt. Zum Verdünnen kann nuneine kleine Menge Verbrennungsgas dem Auspuff entnommen und auf den erforderlichen Einblasedruck verdichtet werden, oder aber es wird auf den. entsprechenden Druck gebrachter bzw. bei diesem Druck erzeugter trockner oder überhitzter Dampf verwendet, der mittels im Arbeitsprozeß anfallender Abhitze erhalten sein kann. Hierbei werden unter mittleren Treibstoffen alle die öle verstanden, deren überwiegende Anteile von i5 o bi's 2 5 o° C sieden, und unter leichteren Treibstoffen solche, deren überwiegende Anteile unter i 5o' C sieden. Durch das Verfahren der vorliegenden Erfindung wird es ermöglicht, anstatt schwerer Dieselöle, die in nicht ausreichender Menge als Inlandserzeugnis zur Verfügung stehen, auch mittlere und leichtere Treibstoffe, deren Anfall in Deutschland wesentlich größer ist, ohne den obengenannten Übelstand als Betriebsstoff für Dieselinoto@ren zu verwenden.According to the present invention. This method, which is known for diesel oil, is applied to medium and lighter fuels in such a way that this fuel is diluted so much by means of inert gas that the combustion process is extended over time, but with complete combustion as a result of the atomization and swirling when blowing in. For dilution, a small amount of combustion gas can now be taken from the exhaust and compressed to the required injection pressure, or it can be added to the. corresponding pressure brought or generated at this pressure dry or superheated steam is used, which can be obtained by means of waste heat generated in the work process. Here, all the oils understood under medium fuels boiling whose predominant proportions of i5 o bi's 2 o 5 ° C, and with lighter fuels such boil whose predominant proportions under i 5o 'C. The method of the present invention makes it possible, instead of heavy diesel oils, which are not available in sufficient quantities as domestic products, to also use medium and lighter fuels, the production of which is much greater in Germany, without the abovementioned inconvenience as fuel for diesel engines use.
