Description

Verfahren zum Betriebe von Verbrennungsmotoren. Für Explosions- und Verbrennungsmotoren, die mit einem schwer entflammbaren Brennstoffluftgemisch betrieben werden, hat man schon die Einführung eines besonderen Brenns toi ffluftgemisches von leichter Entflammbarkeit in den Arbeitszylinder, und zwar in der Nachbarschaft der Zündvorrichtung, vorgeschlagen, damit durch die Zündung des leicht entflammbaren Gemisches die Zündung des schwer entflammbaren Gemisches erleichtert wird. -Das Wesen der Erfindung besteht darin, daß das hochwertigere Brennstoffluftgemisch von großer Entflammbarkeit aus demselben Brennstoff wie das geringwertigere Gemisch besteht, wobei die hohe Entflammbarkeit durch besondere Behandlung einer Teilmenge des geringwertigeren Brennstoffluftgemisches herbeigeführt wird, z. B. durch Überhitzung, bessere Mischung, durch Verwendung von besonders wirksamer Verbrennungsluft (z. B. Sauerstoff) usf. Dadurch wird ein außerordentlich einfacher Betrieb gegenüber der Verwendung von Gemischen mit verschiedenen Brennstoffen herbeigeführt.Process for the operation of internal combustion engines. For explosion and Internal combustion engines operated with a flame-retardant fuel-air mixture one already has the introduction of a special fuel air mixture of easy flammability in the working cylinder, namely in the neighborhood the ignition device, proposed to allow by the ignition of the highly flammable Mixture the ignition of the flame-retardant mixture is facilitated. -That The essence of the invention is that the higher quality fuel-air mixture of great flammability from the same Fuel like the inferior one Mixture consists, whereby the high flammability by special treatment one Partial amount of the inferior fuel-air mixture is brought about, for. B. through overheating, better mixing, through the use of particularly effective combustion air (e.g. oxygen) etc. This makes operation extremely simple compared to the use of mixtures with different fuels brought about.

Wenn dabei die Einführung des leicht entflammbaren Gemisches in der Nachbarschaft der Zündorgane erfolgt, so daß diese ausschließlich in Berührung mit dem leicht entflammbaren Gemisch stehen, so wird jedes Versagen beim Anlaufen des Motors oder bei niedriger Drehzahl desselben vermieden.If the introduction of the easily flammable mixture in the Neighborhood of the ignition organs takes place, so that these only come into contact with the easily flammable mixture, any failure when starting the Engine or at low speed of the same avoided.

Auch kann zur Erhöhung der Zündung des schwer entflammbaren Gemisches die Einführung des leicht entflammbaren Gemisches zu mehreren Zeitpunkten erfolgen, so daß diese Gemischmengen gleichsam zwischen den verschiedenen Teilen des Hauptgemisches schichtenartig verteilt werden und das Fortschreiten der Zündung von einer Schicht zur anderen begünstigen. Schließlich gestattet die Anwendung dieses Verfahrens auch die Einspritzung von Wasser oder Wasserdämpfen in den Zylinder, wodurch an und für sich die Zündungsfähigkeit herabgesetzt wird, aber eine Kühlung des Zylinders ohne Beeinträchtigung des thermischen Wirkungsgrades möglich ist. Eine Einrichtung zur Ausführung des Verfahrens ist beispielsweise auf der Zeichnung schematisch veranschaulicht. Die Verbrennungskammer des Motorzylinders ist mit C, die Zündvorrichtung (Zündkerze) mit a bezeichnet. , Nach der Erfindung wird in die Nachbarschaft der Zündvorrichtung a ein örtliches Volumen i des durch besondere Behandlung leicht entflammbar gemachten Gemisches eingeführt, durch welches die Zündung des schwer entflammbaren Hauptgemisches m erleichtert wird.It can also increase the ignition of the flame-retardant mixture the introduction of the easily flammable mixture takes place at several points in time, so that these mixture quantities, as it were, between the different parts of the main mixture are distributed in layers and the progress of the ignition of one layer to favor the other. Finally, the use of this method also allows the injection of water or water vapors into the cylinder, creating on and for the ignitability is reduced, but a cooling of the cylinder without Impairment of the thermal efficiency is possible. A facility for Execution of the method is illustrated schematically, for example, on the drawing. The combustion chamber of the engine cylinder is marked with C, the ignition device (spark plug) denoted by a. , According to the invention, in the vicinity of the ignition device a a local volume i of that which has been made easily flammable by special treatment Mixture introduced through which the ignition of the flame-retardant main mixture m is facilitated.
