Description
Die Erfindung betrifft eine Brennkraftmaschine gemäß dem Ober begriff des Patentanspruchs 1.The invention relates to an internal combustion engine according to the Ober Concept of claim 1.
Derartige Brennkraftmaschinen bieten insbesondere dann, wenn die Zylinder der beiden Zylinderreihen sich in Längsrichtung, also in Richtung der Kurbelwellenachse, der Maschine in abwechselnder Folge teilweise überdecken, den Vorteil eines besonders platz sparenden Aufbaus, und zwar sowohl in Längsrichtung als auch in Querrichtung. Eine solche gattungsgemäße Brennkraftmaschine ist aus der DE 27 40 173 A1 bekannt.Such internal combustion engines offer especially when the Cylinders of the two rows of cylinders are longitudinal, that is in the direction of the crankshaft axis, the machine in alternating Partially cover episode, the advantage of a particularly space saving construction, both in the longitudinal direction and in Cross direction. Such a generic internal combustion engine is known from DE 27 40 173 A1.
Der Erfindung liegt die Aufgabe zugrunde, die sich bei einer der artigen Brennkraftmaschine ergebenden besonderen konstruktiven Ver hältnisse zu einerweiteren Verringerung der Abmessungen der Ma schine insbesondere in Richtung ihrer Kurbelwellenachse auszu nutzen.The invention is based, which is one of the task like internal combustion engine resulting special constructive ver conditions to further reduce the dimensions of the dimensions seem particularly in the direction of their crankshaft axis use.
Die erfindungsgemäße Lösung dieser Aufgabe besteht in den kennzeich nenden Merkmalen des Patentanspruchs 1, vorteilhafte Aus- und Weiter bildungen der Erfindung beschreiben die Unteransprüche.The inventive solution to this problem consists in the character nenden features of claim 1, advantageous further and next Formations of the invention describe the dependent claims.
Dabei sind die Merkmale des Anspruchs 2 für sich aus der US 32 30 074 bekannt. Ein besonderer Vorteil der Erfindung ist darin zu sehen, daß die Lösung der gestellten Aufgabe ohne jeglichen zusätzlichen konstruk tiven Aufwand und ohne Beeinflussung der Arbeitsweise der Maschine oder ihrer Hilfsaggregate erfolgt. 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 wesent licher Teile von Pumpen und/oder Antriebsmitteln ausgenutzt.Are the features of claim 2 known per se from US 32 30 074. A particular advantage of the invention is that the Solution of the task without any additional construct tive effort and without influencing the operation of the machine or their auxiliary units. It will only be the resulting from the described cylinder offset, otherwise unused space next to the protruding end cylinder and in front of the reset end cylinder to accommodate at least essential Licher parts of pumps and / or drive means used.
Zwei Ausführungsbeispiele der Erfindung werden im folgenden an hand der Zeichnung erläutert. Es stellen darTwo embodiments of the invention are set out below hand of the drawing explained. It represent
Fig. 1 eine Frontansicht einer erfindungsgemäß aus gestalteten Brennkraftmaschine, Fig. 1 is a front view of a according to the invention, designed from the internal combustion engine
Fig. 2 die in Fig. 1 bei II-II angedeutete Schnitt ansicht und Fig. 2 shows the sectional view indicated in Fig. 1 at II-II and
Fig. 3 eine Schnittansicht etwa gemäß II-II in Fig. 1 für eine zweite Ausführungsform. Fig. 3 is a sectional view approximately according to II-II in Fig. 1 for a second embodiment.
Betrachtet man zunächst die Fig. 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 so angeordnet, daß die Zylinderachsen, wie in Fig. 1 nur für die Zylinderachsen 1′ und 3′ dargestellt, sich etwa auf der Achse der Kurbelwelle 6 schneiden. Durch den Längsversatz der Zylinder der beiden Zylinder reihen ergibt sich neben dem infolge des Versatzes der Zylinder reihen in Richtung der Achsen der Kurbelwelle 6 vorstehenden End zylinder 1 der einen Zylinderreihe und vor dem infolge dieses Ver satzes zurückgesetzten Endzylinder 3 der anderen Zylinderreihe prak tisch ungenutzter Raum innerhalb des Umrisses der Maschine, der er findungsgemäß zur Unterbringung der Ölpumpe 7, der Wasserpumpe 8 sowie von Antriebsmitteln ausgenutzt wird, die zum Antrieb der Pumpen 7 und 8 sowie der oben liegenden Nockenwelle 9 von der Kurbelwelle 6 her dienen. Dies sind in dem gezeigten Ausführungsbeispiel übliche und daher im einzelnen nicht zu beschreibende Zahnscheiben und Zahn riemen 10.Looking first at Figs. 1 and 2, the cylinders 1 , 2 , 3 and 4 of the machine in the generally designated 5 housing thereof are arranged in two rows 1 , 2 and 3 , 4 so that the cylinder axes, as in Fig. 1 shown only for the cylinder axes 1 'and 3 ', cut approximately on the axis of the crankshaft 6 . By the longitudinal offset of the cylinders of the two cylinders rows results in addition to the resulting due to the offset of the cylinders in the direction of the axes of the crankshaft 6 end cylinder 1 of the one row of cylinders and before the set as a result of this Ver reset cylinder 3 of the other row of cylinders practically unused space within the outline of the machine, which he uses according to the invention to accommodate the oil pump 7 , the water pump 8 and drive means which serve to drive the pumps 7 and 8 and the overhead camshaft 9 from the crankshaft 6 . In the exemplary embodiment shown, these are customary and therefore toothed pulleys and toothed belts 10, which cannot be described in detail.
In dem den Fig. 1 und 2 zugrundeliegenden Ausführungsbeispiel ist das Gehäuse 5 der Maschine an dieser Stelle, wie bei 11 ange deutet, eingezogen, so daß der für die Unterbringung der Antriebs mittel dort zur Verfügung stehende Raum 12 außerhalb des Gehäuses 5 liegt. In the embodiment of FIGS. 1 and 2, the housing 5 of the machine at this point, as indicated at 11 , is drawn in, so that the space 12 available there for accommodating the drive means lies outside the housing 5 .
Betrachtet man demgegenüber Fig. 3, in der die Zylinder wiederum mit 1, 2, 3 und 4 bezeichnet sind, so ist dort das Gehäuse 20 ne ben dem vorstehenden Endzylinder 1 nicht eingezogen, so daß Öl- und Wasserpumpe in einem innerhalb des Gehäuses liegenden Bereich 21 untergebracht sind. Innerhalb des Gehäuses ist zwischen aufeinander folgenden Zylindern 3 und 4 einer der beiden Zylinderreihen bei 22 auch Raum für die Aufnahme eines Kühlmittelthermostaten, so daß auch dieser in einem sonst unausgenutzten Bereich des Gehäuses an geordnet ist.Considering other hand, Fig. 3, in which the cylinders are again denoted by 1, 2, 3 and 4, there is shown the housing 20 ne ben the protruding end cylinders 1 is not drawn in, so that oil and water pump in a region lying within the housing Area 21 are housed. Within the housing between successive cylinders 3 and 4 one of the two rows of cylinders at 22 also space for receiving a coolant thermostat, so that this is also arranged in an otherwise unused area of the housing.
