Description

Luft- oder Gaszuführung durch Zylinderschlitze bei Verbrennungskraftmaschinen, insbesondere Zweitaktdieselmaschinen Es ist zwar bereits bekannt geworden, bei Zweitaktverbrennungskraftmaschinen von beiden Seiten die Luft den Zylinderschlitzen zuzuführen, jedoch waren hierbei keine bis zu der Zylinderseele reichende Trennungswände zwischen den beiden Zuführungen vorgesehen. Da es sich nun infolge der immer vorhandenen verschiedenen Rohrleitungswiderstände nicht erreichen läßt, daß der Luftdruck in beiden Zuführungsleitungen an der Stelle der Schlitze gleich groß ist, so hat sich bei derartigen Ausführungen der Nachteil gezeigt, daß die von der einen Seite kommende Luft höheren Druckes die von der anderen Seite kommende Luft niederen Druckes teilweise zurückdrängt, bevor letztere in die Zylinderschlitze eindringen kann. Es entstehen hierbei Wirbelungen, die zu Verlusten Anlaß geben. Weitere Verluste werden dadurch hervorgerufen, daß derjenige Teil der Luft höheren Druckes, welcher die Zylindermitte überschreitet, starke Krümmungen ausführen muß, um durch die Schlitze in das Innere des Zylinders eintreten zu können.Air or gas supply through cylinder slots in internal combustion engines, in particular two-stroke diesel engines It is already known in two-stroke internal combustion engines to supply the air to the cylinder slots from both sides, but were here no partition walls between the two inlets reaching up to the cylinder core intended. Since it is now due to the various pipe resistances that are always present can not achieve that the air pressure in both supply lines at the point If the slots are of the same size, there is a disadvantage in such designs showed that the air coming from one side is of higher pressure than that from the other Side partially pushes back incoming air of low pressure before the latter into the Cylinder slots can penetrate. This creates eddies that lead to losses To give reason. Further losses are caused by the fact that that part of the Air of higher pressure, which exceeds the cylinder center, strong curvatures must perform in order to be able to enter the interior of the cylinder through the slots.

Die Erfindung vermeidet nun die obenerwähnten Übelstände dadurch, daß bei zwei-oder mehrseitiger Zuführung der Luft oder des Gases zu den auf dem Umfang des Zylinders einer Verbrennungskraftmaschine gleichmäßig verteilten Schlitzen die einzelnen Zuführungskanäle voneinander durch bis zu der Zylinderseele reichende Zwischenwände getrennt sind, so daß auch bei nicht ganz gleichem Druck des Mittels in den einzelnen Zuführungskanälen Wirbelungen infolge gegenseitiger Beeinflussung der Luft- oder Gasströme nicht auftreten können und das Mittel ohne zu starke Richtungsänderung den einzelnen Schlitzen zugeführt wird.The invention now avoids the abovementioned inconveniences by that with two or more sides supply of air or gas to the on the Perimeter of the cylinder of an internal combustion engine evenly distributed slots the individual supply channels from each other by reaching up to the cylinder core Partitions are separated, so that even if the pressure of the agent is not quite the same in the individual supply channels eddies as a result of mutual influence the air or gas flows cannot occur and the means without too great a change in direction is fed to the individual slots.

Die Erfindung eignet sich besonders für die Spülluftschlitze von Zweitaktdieselmaschinen, da bei diesen Maschinen eine besonders gleichmäßige Spülluftströmung im Zylinderinnern erforderlich ist.The invention is particularly suitable for the purge air slots of two-stroke diesel engines, because these machines have a particularly even flow of scavenging air inside the cylinder is required.

Die Zeichnung zeigt eine beispielsweise Ausführung @ der Erfindung bei Anordnung von tangential gerichtetenZuführungskanälen.The drawing shows an example embodiment @ of the invention with the arrangement of tangentially directed feed channels.

Es bezeichnen a den Zylinder, b die Spülschlitze und c das Gehäuse für die Zuführung des gasförmigen Mittels, das mit den beiden Eintrittsöffnungen d und e versehen ist. In der Mitte zwischen diesen öffnungen ist das Gehäuse mit Trennungswänden f und g versehen.It designate a cylinder, the scavenging ports b and c, the housing for the supply of the gaseous agent d with the two inlet openings and e is provided. In the middle between these openings, the housing is provided with partition walls f and g.
