Description

Die Erfindung betrifft eine luftgekühlte Zweitakt-Brennkraftmaschine mit zwei in V-Form angeordneten Zylinderreihen, bei der die Zylinder mit den Zylinderköpfen an einer zur Zylinderachse senkrechten Wand des hochgezogenen Maschinengestells aufgehängt sind und bei welcher der Raum zwischen den Zylindern als Aufnehmer für die Kühlluft dient.The invention relates to an air-cooled two-stroke internal combustion engine with two rows of cylinders arranged in a V-shape, in which the cylinders are connected to the cylinder heads on a wall of the raised machine frame perpendicular to the cylinder axis are suspended and in which the space between the cylinders acts as a sensor for the cooling air is used.

Die Erfindung besteht darin, daß der Kühlluftaufnehmerraum oben durch eine mit dem Maschinengestell einstöckig verbundene Wand abgeschlossen ist, indem dieseWand bis an dieBefestigungswände für die Aufhängung der Zylinder und der Zylinderköpfe herangeführt ist.The invention consists in that the cooling air pick-up space through the top a one-story wall connected to the machine frame is completed by this wall up to the fastening walls for the suspension of the cylinders and cylinder heads is introduced.

Es ist eine wassergekühlte V-förmigeBrennlzraftmaschine bekannt, bei welcher der Raum zwischen den Zylinderreihen oben durch einen Blechdeckel abgeschlossen ist. Der Blechdeckel ist aber nicht dort angesetzt, wie es bei der luftgekühlten Brennkraftmaschine nach der neuen Erfindung der Fall ist. Der Blechdeckel ist im -Bereich des unteren Endes des Zylinderkopfes an das Maschinengestell angesetzt. Gemäß der neuen Erfindung liegt der Anschluß der Abdeckwand wesentlich höher, und zwar so hoch, wie es nur möglich ist, damit das Maschinengestell einen hohen Träger bildet, der ein großes Widerstandsrrioment hat. Dies ist für luftgekühlte Brennkraftmaschinen besonders wichtig, weil diese im Gegensatz zu wassergekühlten Brennkraftmaschinen viel weniger versteifende Wände im Maschinengestell haben. Bei einem'weiteren bekannten Zweitaktdieselmotor mit Wasserkühlung hat das wassergekühlte Maschinengestell oben eine Abdeckwand. Auch bei diesem Dieselmotor ist die Abdeckwand im Bereich der unteren Enden der Zylinderköpfe an das Maschinengestell herangeführt.A water-cooled V-shaped fuel engine is known at which the space between the rows of cylinders is closed off by a sheet metal cover at the top is. The sheet metal lid is not attached there, as is the case with the air-cooled one Internal combustion engine according to the new invention is the case. The sheet metal lid is in -Area of the lower end of the cylinder head attached to the machine frame. According to the new invention, the connection of the cover wall is much higher, and as high as it is possible to give the machine frame a high support forms, which has a large drag torque. This is for air-cooled internal combustion engines especially important because this is in contrast to water-cooled internal combustion engines have far fewer stiffening walls in the machine frame. Another known one The two-stroke diesel engine with water cooling has the water-cooled machine frame at the top a cover wall. In this diesel engine, too, the cover wall is in the area of the lower one The ends of the cylinder heads are brought up to the machine frame.

In der Zeichnung ist eine Ausführungsform der Erfindung beispielsweise dargestellt.In the drawing, an embodiment of the invention is for example shown.

Die Zeichnung zeigt eine luftgekühlte Zweitakt-Brennkraftmaschine mit zwei in V-Form angeordneten Zylinderreihen im senkrechten Querschnitt. Bei der Zweitakt-Brennkraftmaschine sind die Zylinderköpfe i an einer zur Zylinderachse senkrechten Wand :2 des hochgezogenen Maschinengestells 3 befestigt. Der Raum 4 zwischen den beiden Zylinderreihen dient als Aufnehmer für die Kühlluft, die beispielsweise mit Hilfe eines Gebläses in den Raum 4 hineingeblasen wird und durch das Maschinengestell 3 um die Zylinder herumgeleitet nach außen abströmt. Die Zweitakt-Brennkraftmaschine weist die Besonderheit auf, daß der Kühlluftaufnehmerraum 4 oben durch eine mit dem Maschinengestell 3 einstöckig verbundene Wand 5 abgeschlossen ist, indem diese Wand 5 bis an die Befestigungswände 2 für die Zylinderköpfe i herangeführt ist.The drawing shows an air-cooled two-stroke internal combustion engine with two rows of cylinders arranged in a V-shape in a vertical cross-section. In the Two-stroke internal combustion engine are the cylinder heads i on one to the cylinder axis vertical wall: 2 of the raised machine frame 3 attached. The room 4 between the two rows of cylinders serves as a sensor for the cooling air, for example is blown into the room 4 with the help of a fan and through the machine frame 3 flows around the cylinder to the outside. The two-stroke internal combustion engine has the peculiarity that the cooling air pick-up space 4 is topped by a the machine frame 3 integrally connected wall 5 is completed by this Wall 5 is brought up to the mounting walls 2 for the cylinder heads i.

Eine vorteilhafte weitere Ausgestaltung der Erfindung besteht darin, daß der Kühlluftaufnehmerraum 4 an den beiden Enden der Maschine, was der Einfachheit halber jedoch nicht dargestellt ist, durch mit der Abdeckwand 5 und mit dem hochgezogenen Maschinengestell 3 einstöckig verbundene Wände verschlossen ist. Dadurch wird die Steifheit des Maschinengestells weiterhin beträchtlich erhöht.An advantageous further embodiment of the invention consists in that the cooling air intake space 4 at the two ends of the machine, what simplicity sake is not shown, however, by with the cover wall 5 and with the raised Machine frame 3 one-story connected walls is closed. This will make the The rigidity of the machine frame continues to be increased considerably.

Die Verschlußwände sind zweckmäßig so ausgebildet, daß sie zur Befestigung der für die Maschine benötigten Gebläse, z. B. der Kühl-, Spül- oder Ladegebläse, dienen. Diese Gebläse @ können mit kreisförmigen Zentrierungen in entsprechenden Zentrierungen der Wände, die auch als Anschläge für die von den Gebläsen geförderten Mittel dienen, eingesetzt werden.The closure walls are expediently designed so that they are used for fastening the fan required for the machine, e.g. B. the cooling, rinsing or loading fan, to serve. These fans @ can with circular centerings in corresponding Centering of the walls, which also act as stops for those promoted by the fans Means serve, are employed.
