Description

Luftverdichtende Zweitakt-Brennkraftmaschine mit Verdrängerwirkung des Kolbens, insbesondere für Schweröle Die Erfindung betrifft eine luftverdichtende Zweitakt-Brennkraftmaschine mit Verdrängerwirkung des Kolbens, insbesondere für den Betrieb mit Schwerölen, und strebt eine besonders günstige Verwirbelung der verdichteten Luft mit dem eingespritzten Brennstoff zum Zwecke einer vollkommenen Verbrennung an, derart, daß die Maschine mit hohen Drehzahlen arbeiten kann. Erfindungsgemäß ist der Kolbenboden auf einem erhöhten mittleren, den Verdrängerrand bildenden Teil mit einer Ringnut versehen, die sich in der oberen Totlage des Kolbens mit einer entsprechenden Ringnut eines abgesetzten mittleren Teiles des Zylinderkopfes zu einer ringwulstförmigen Verbrennungskammer mit kreisförmiger Drehfläche ergänzt. In dem Verdrängerrand des Kolbenbodens sind tangential oder annähernd tangential zu dem Umfang der kreisförmigen Drehfläche der Verbrennungskammer durchgehende Kanäle vorgesehen, durch welche der größte Teil der durch den Kolben verdichteten Luft in die Verbrennungskammer strömt, so daß darin eine wirbelnde, um die Ringachse kreisende Bewegung erzeugt wird.Air-compressing two-stroke internal combustion engine with displacement effect of the piston, especially for heavy oils The invention relates to an air-compressing Two-stroke internal combustion engine with displacement effect of the piston, especially for the operation with heavy oils, and strives for a particularly favorable turbulence of the compressed air with the injected fuel for the purpose of a perfect Combustion in such a way that the machine can operate at high speeds. According to the invention is the piston crown on a raised central part that forms the displacer edge provided with an annular groove, which is in the top dead center of the piston with a corresponding annular groove of a remote central part of the cylinder head an annular bead-shaped combustion chamber with a circular rotating surface. In the displacement edge of the piston head are tangential or approximately tangential channels continuous to the periphery of the circular surface of revolution of the combustion chamber provided through which most of the air compressed by the piston flows into the combustion chamber, so that it swirls around the ring axis circular motion is generated.

Es sind bereits Zweitakt-Brennkraftmaschinen mit ringwulstförmiger Verbrennungskammer bekannt, in welche schräg gerichtete Luftkanäle einmünden. Diese Kanäle sind jedoch nur dazu bestimmt, einen kleinen Teil der Luft hindurchtreten zu lassen zu dem Zweck, die Hauptluftmenge, die durch einen mittleren, senkrechten Kanal in die Verbrennungskammer eintritt, in Bewegung zu versetzen. Bei der Anordnung nach der Erfindung dagegen strömt der Hauptteil der Luft durch die im Verdrängerrand vorgesehenen Kanäle, so daß in der Verbrennungskammer eine wirbelnde Bewegung erzeugt wird, die eine kräftige Durchmischung von Luft und Brennstoff sichert.There are already two-stroke internal combustion engines with an annular ring Combustion chamber known into which obliquely directed air ducts open. These However, ducts are only intended to allow a small portion of the air to pass through to let the main air flow through a middle, vertical Channel enters the combustion chamber to set in motion. In the arrangement according to the invention, however, the main part of the air flows through the in the displacement edge provided channels, so that a whirling movement is generated in the combustion chamber that ensures a vigorous mixing of air and fuel.

Die Erfindung ist in der Ausführungsform in der Zeichnung veranschaulicht, die den oberen Teil des Zylinders darstellt.The invention is illustrated in the embodiment in the drawing, which represents the upper part of the cylinder.

i ist der Kopf des Zylinders, in dem der Kolben 7 arbeitet. Der Kolbenboden ist auf seinem erhöhten mittleren Teil, der als Verdränger dient, mit einer Ringnut i' versehen. Auch der abgesetzte mittlere Teil des Zylinderkopfes enthält eine Ringnut, die in der oberen Totlage des Kolbens mit der entsprechenden Ringnut des Kolbenbodens eine ringwulstförmige Verbrennungskammer bildet. In dem Verdrängerrand 2 des Kolbens sind tangential zu dem Umfang der kreisförmigen Drehfläche der Verbrennungskammer einmündende Kanäle g vorgesehen, durch welche die verdichtete Luft in die Verbrennungskammer eintritt. Die Luft erfährt in der Verbrennungskammer eine Drehbewegung im Sinne des Pfeiles C, die der Drehbewegung im Sinne des Pfeiles B des aus dem ringförmigen Schlitz io austretenden Teiles der Luft .entgegenwirkt.i is the head of the cylinder in which the piston 7 works. The piston crown is on its raised central part, which serves as a displacer, with an annular groove i 'provided. The offset middle part of the cylinder head also contains an annular groove, the one in the upper dead position of the piston with the corresponding ring groove of the piston crown forms a toroidal combustion chamber. In the displacement edge 2 of the piston are tangential to the periphery of the circular surface of revolution of the combustion chamber Opening channels g are provided through which the compressed air enters the combustion chamber entry. The air experiences in the combustion chamber a twisting motion in the direction of arrow C, the rotational movement in the direction of arrow B from the ring-shaped slot io exiting part of the air. counteracts.

Die Anordnung nach der Erfindung hat die Wirkung, daß während des ganzen Verdrängervorganges ein maximaler Durchgang für die Luft aus dem Hubraum in den Brennraum gesichert wird, wodurch die Verbrennung beschleunigt, daher die Drehzahl des Motors gesteigert und das Maschinengewicht bei gegebener Leistung vermindert werden kann.The arrangement according to the invention has the effect that during the whole displacement process a maximum passage for the air from the displacement is secured in the combustion chamber, thereby accelerating the combustion, hence the The engine speed increased and the weight of the machine reduced for a given output can be.
