Abstract

In order to reduce the dimensions of an internal combustion engine with cylinders (1, 2; 3, 4) arranged in two rows offset in an axial direction, the oil and/or water pump (7, 8) and/or the drive means (toothed belt 10) for this are arranged next to the end cylinder (1) of one of the rows of cylinders, which projects due to the cylinder offset alignment, and in front of the end cylinder (3) of the other row of cylinders, which is set back owing to the cylinder offset alignment (Figure 1). <IMAGE>

Es wird lediglich der sich infolge des beschriebenen Zylinderversatzes ergebende, sonst ungenutzte Raum neben dem vorstehenden Endzylinder und vor dem zurückgesetzten Endzylinder zur Unterbringung zumindest wesentlicher Teile von Pumpen und/oder Antriebsmitteln ausgenutzt.or their auxiliary units. It just becomes the yourself as a result of the cylinder offset described, otherwise unused space next to the preceding end cylinder and in front of the Recessed end cylinder used to accommodate at least essential parts of pumps and / or drive means.

Zwei Ausführungsbeispiele der Erfindung werden im folgenden anhand der Zeichnung erläutert. Es stellen dar:Two embodiments of the invention are based on the following the drawing explained. They represent:

Figur 1 eine Frontansicht einer erfindungsgemäß ausgestalteten Brennkraftmaschine,Figure 1 is a front view of a designed according to the invention Internal combustion engine,

Figur 2 die in Figur 1 bei II-II angedeutete Schnittansicht undFIG. 2 shows the sectional view indicated in FIG. 1 at II-II and

Figur 3 eine Schnittansicht etwa gemäß II-II in Figur 1 für eine, zweite Ausführungsform.FIG. 3 shows a sectional view approximately according to II-II in FIG 1 for a second embodiment.

Betrachtet man zunächst die Figuren 1 und 2, so sind die Zylinder 1,2, 3 und 4 der Maschine in dem allgemein mit 5 bezeichneten Gehäuse derselben in zwei Reihen 1,2 und 3» 4 s° angeordnet, daß die Zylinderachsen, wie in Figur 1 nur für die Zylinderachsen 1' und 31 dargestellt, sich etwa auf der Achse der Kurbelwelle 6 schneiden. Durch den Längsversatz der Zylinder der beiden Zylinderreihen ergibt sich neben dem infolge des Tersatzes der Zylinderreihen in Richtung der Achsen der Kurbelwelle 6 vorstehenden Endzylinder 1 der einen Zylinderreihe und vor dem infolge dieses Yersatzes zurückgesetzten Endzylinder 3 eier anderen Zylinderreihe praktisch ungenutzter Raum innerhalb des Umrisses der Maschine, der erfindungsgemäß zur Unterbringung der Ölpumpe 7, der Wasserpumpe 8 sowie von Antriebsmittel ausgenutzt wird, die zum Antrieb der Pumpen 7 und 8 sowie der oben, liegenden Nockenwelle 9 von der Kurbelwelle her dienen. Dies sind in dem gezeigten Ausführungsbeispiel übliche und daher im einzelnen nicht zu beschreibende Zahnscheiben und Zahnriemen 10.Looking first at FIGS. 1 and 2, the cylinders 1, 2, 3 and 4 of the machine are arranged in the housing, generally designated 5, of the same in two rows 1, 2 and 3 >> 4 s °, so that the cylinder axes, as in FIG Figure 1 is shown only for the cylinder axes 1 'and 3 1 , intersect approximately on the axis of the crankshaft 6. The longitudinal offset of the cylinders of the two rows of cylinders results in practically unused space within the outline of the machine in addition to the end cylinder 1 of the one cylinder row protruding due to the offset of the cylinder rows in the direction of the axes of the crankshaft 6 and in front of the end cylinder 3, which is set back as a result of this offset, another cylinder row , which is used according to the invention to accommodate the oil pump 7, the water pump 8 and drive means which are used to drive the pumps 7 and 8 and the camshaft 9 at the top from the crankshaft. In the exemplary embodiment shown, these are conventional toothed disks and toothed belts 10 that cannot be described in detail.

In dem den Figuren 1 und 2 zugrundeliegenden Ausführungsbeispiel ist das Gehäuse 5 der Maschine an dieser Stelle, wie bei 11 angedeutet, eingezogen, so daß der für die Unterbringung der Antriebsmittel dort zur Verfügung stehende Raum 12 außerhalb des Gehäuses liegt.In the exemplary embodiment on which FIGS. 1 and 2 are based, the housing 5 of the machine is at this point, as indicated at 11, drawn in, so that the space 12 available there for accommodating the drive means is outside the housing lies.

Betrachtet man demgegenüber !Figur 3» in der die Zylinder wiederum mit 1,2, 3 TMxL 4 bezeichnet sind, so ist dort das Gehäuse 20 neben dem vorstehenden Endzylinder 1 nicht eingezogen, so daß Öl- und Wasserpumpe in einem innerhalb des Gehäuses liegenden Bereich untergebracht sind. Innerhalb des Gehäuses ist zwischen aufeinanderfolgenden Zylindern 3 imcl 4 einer der beiden Zylinderreihen bei auch Raum für die Aufnahme eines Kühlmittelthermostaten, so daß auch dieser in einem sonst unausgenutzten Bereich des Gehäuses angeordnet ist.On the other hand, if you look at FIG. 3, in which the cylinders are in turn with 1, 2, 3 TMxL 4 are designated, so there is the housing 20 next the protruding end cylinder 1 is not drawn in, so that the oil and water pump in an area lying within the housing are housed. Inside the housing, one of the two rows of cylinders is between successive cylinders 3 and 4 there is also space to accommodate a coolant thermostat, so that this too is arranged in an otherwise unused area of the housing is.
