Abstract

A piston (2), having a plurality of piston rings (3), is arranged such that it can move in the cylinder insert (1). In a plane located at right angles to the longitudinal axis of the cylinder insert (1), there is provided a series of lubricating oil holes (5), which are connected to a common lubricating oil supply (7) and which terminate in lubricating slots (5') in the jacket surface of the cylinder insert. In the cylinder insert (1), there is provided a further row of lubricating oil holes (6), which are arranged at right angles to the cylinder axis, are connected to a common lubricating oil supply (8) and likewise terminate in lubricating slots (6') in the jacket surface of the cylinder insert. The two lubricating oil supplies (7 and 8) are independent from one another. The first-mentioned row of lubricating oil holes (5) is located in a region which - related to the position of the uppermost piston ring (3) at top dead centre - is located beneath this position, at between 5 and 18% of the piston stroke, while, on the other hand, the further row of lubricating oil holes (6) is located in a region below them, at between 20 and 40% of the piston stroke.

Description

Die Erfindung betrifft eine Hubkolbenbrennkraftmaschine mit mindestens einem Zylindereinsatz, in dem ein mehrere Kolbenringe aufweisender Kolben beweglich angeordnet ist, und mit einer im wesentlichen in einer rechtwinklig zur Längsachse des Zylindereinsatzes liegenden Ebene angeord­neten Reihe von Schmierölbohrungen, die an eine gemeinsa­me Schmierölzuführung angeschlossen sind und die in Schmiernuten enden, die in der dem Kolben benachbarten Mantelfläche des Zylindereinsatzes angebracht sind.The invention relates to a reciprocating piston internal combustion engine with at least one cylinder insert, in which a piston having a plurality of piston rings is movably arranged, and with a row of lubricating oil bores arranged essentially in a plane lying at right angles to the longitudinal axis of the cylinder insert, which are connected to a common lubricating oil supply and which in Lubricate grooves that are located in the outer surface of the cylinder insert adjacent to the piston.

Bisher war es üblich, nur eine Reihe von Schmierölbohrun­gen mit -nuten im Zylinder anzubringen, und zwar entweder in dessen oberen Endbereich oder relativ weit unten am Zylindereinsatz. Hierdurch wurde die Schmierung in verschiedener Weise beeinflusst. Im erstgenannten Fall werden durch die Verbrennungsprodukte bedingte Korrosi­onsangriffe im Zylindereinsatz vermindert oder sogar verhindert, wobei dann die Schmierung im unteren Bereich des Zylindereinsatzes ungenügend sein kann, was grosse Abnutzung bedeutet. Bei Anordnung der Schmierölbohrungs­reihe im unteren Bereich des Zylindereinsatzes wird eine gute Schmierung des unteren Abschnitts des Zylinderein­satzes gewährleistet, jedoch ist der Schutz gegen Korro­sionsangriffe im oberen Bereich des Zylindereinsatzes unbefriedigend. Für die Schmierung wird in beiden Fällen ein Schmieröl mit einer hohen TBN (total base number) angewendet, d.h. ein hochalkalisches Schmieröl mit Additiven.Until now, it was common to make only one row of lubricating oil bores with grooves in the cylinder, either in its upper end area or relatively far down on the cylinder insert. This affected the lubrication in different ways. In the former case, corrosion attacks in the cylinder insert caused by the combustion products are reduced or even prevented, in which case the lubrication in the lower region of the cylinder insert can be insufficient, which means great wear and tear. When the row of lubricating oil bores is arranged in the lower region of the cylinder insert, good lubrication of the lower section of the cylinder insert is ensured, but the protection against corrosion attacks in the upper region of the cylinder insert is unsatisfactory. In both cases, a lubricating oil with a high TBN (total base number) is used for lubrication applied, ie a highly alkaline lubricating oil with additives.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Hubkolbenbrennkraftmaschine der eingangs genannten Art die Schmierung so zu verbessern, dass sowohl der Korrosi­onsangriff als auch die Abnutzung drastisch verringert werden.The invention has for its object to improve the lubrication in a reciprocating internal combustion engine of the type mentioned in such a way that both the corrosion attack and wear are drastically reduced.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass im Zylindereinsatz eine weitere, im wesentlichen in einer rechtwinklig zur Längsachse des Zylindereinsatzes liegen­den Ebene angeordnete Reihe von Schmierölbohrungen vorgesehen ist, die an eine gemeinsame Schmierölzuführung angeschlossen sind und die in Schmiernuten enden, die in der dem Kolben benachbarten Mantelfläche des Zylinderein­satzes angebracht sind, dass die Schmierölzuführung zur weiteren Reihe von der zur erstgenannten Reihe unabhängig ist und dass die erstgenannte Reihe von Schmierölbohrun­gen in einem Bereich liegt, der - bezogen auf die Lage des obersten Kolbenringes im oberen Totpunkt - sich unterhalb dieser Lage befindet und dessen Grenzen zwi­schen 5 und 18 % des Kolbenhubes liegen, und die weitere Reihe von Schmierölbohrungen in einem darunter befindli­chen Bereich liegt, dessen Grenzen zwischen 20 und 40 % des Kolbenhubes liegen. Durch diese Gestaltung ist man in der Lage, die Schmierölzufuhr zu jedem Schmierbereich den in diesen beiden Bereichen unterschiedlichen Betriebsbe­dingungen entsprechend individuell anzupassen. Dies kann dadurch geschehen, dass den beiden Schmierbereichen gleiche oder unterschiedliche Mengen desselben Schmier­mittels oder gleiche oder unterschiedliche Mengen zweier verschiedener Schmiermittel zugeführt werden.According to the invention, this object is achieved in that a further row of lubricating oil bores is provided in the cylinder insert, essentially arranged in a plane perpendicular to the longitudinal axis of the cylinder insert, which are connected to a common lubricating oil supply and which end in lubricating grooves that adjoin the piston in the one Shell surface of the cylinder insert are attached, that the lubricating oil supply to the further row is independent of the first row and that the first-mentioned row of lubricating oil holes is in an area which - based on the position of the top piston ring in top dead center - is below this position and whose limits are between 5 and 18% of the piston stroke, and the further series of lubricating oil holes is in an area below, whose limits are between 20 and 40% of the piston stroke. This design enables the lubricating oil supply to each lubrication area to be individually adapted to the different operating conditions in these two areas. This can be done by adding the same or different amounts of the same lubricant or the same or different amounts of two different lubricants to the two lubrication areas.

Ein Ausführungsbeispiel der Erfindung wird in der folgen­den Beschreibung anhand der Zeichnung näher erläutert, die einen Längsschnitt durch einen Teil eines Zylinder­einsatzes und die Ansicht eines Teils eines darin befind­lichen Kolbens zeigt.An embodiment of the invention is explained in more detail in the following description with reference to the drawing, which shows a longitudinal section through part of a cylinder insert and the view of part of a piston located therein.

Gemäss der Zeichnung ist in einem Zylindereinsatz 1, der in bekannter Weise in einen nicht dargestellten Zylinder­block einer Hubkolbenbrennkraftmaschine der Dieselbauart angeordnet und wassergekühlt ist, ein Kolben 2 auf- und abbeweglich geführt. In der dargestellten Stellung hat der Kolben 2 die obere Totpunktstellung inne. Der Kolben 2 ist mit mehreren Kolbenringen 3 versehen, die in bekannter Weise in Ringnuten des Kolbens untergebracht sind und mit ihrer äusseren Umfangsfläche an der inneren Mantelfläche 1′ des Zylindereinsatzes 1 anliegen.According to the drawing, in a cylinder insert 1, which is arranged in a known manner in a cylinder block, not shown, of a reciprocating piston internal combustion engine of the diesel type and is water-cooled, a piston 2 is guided to move up and down. In the position shown, the piston 2 is in the top dead center position. The piston 2 is provided with a plurality of piston rings 3, which are accommodated in a known manner in ring grooves of the piston and bear with their outer peripheral surface on the inner circumferential surface 1 'of the cylinder insert 1.

Im oberen Bereich des Zylindereinsatzes 1 ist eine Reihe von Schmierölbohrungen 5 vorgesehen, die den Zylinderein­satz durchdringen und in einer im wesentlichen recht­winklig zur Längsachse des Zylindereinsatzes liegenden Ebene an der Mantelfläche 1′ enden. Der Bereich, in dem die Schmierölbohrungen 5 angeordnet sind, liegt unterhalb des obersten Kolbenringes 3, wenn der Kolben 2 seine obere Totpunktlage inne hat. Die Grenzen dieses Bereiches liegen zwischen 5 und 18 % des Kolbenhubes. Unterhalb des so gebildeten Schmierbereiches befindet sich eine zweite Reihe von Schmierölbohrungen 6, die ebenfalls in einer im wesentlichen zur Längsachse des Zylindereinsatzes 1 rechtwinkligen Ebene in der Mantelfläche enden. Der durch diese Schmierölbohrungen 6 gebildete, zweite Schmierbe­reich hat seine Grenzen zwischen 20 und 40 % des Kolben­hubes. Die Schmierölbohrungen 5 und 6 münden in Schmier­nuten 5′ bzw. 6′, die in die innere Mantelfläche 1′ des Zylindereinsatzes 1 eingearbeitet sind und sich quer zur Bewegungsrichtung des Kolbens 2 erstrecken. An jede Reihe der Schmierölbohrungen 5 und 6 ist eine eigene Schmier­ölzuführung 7 bzw. 8 angeschlossen und jede von diesen enthält ein Einstellorgan 9 bzw. 10, um die der zugehöri­gen Schmierölbohrungsreihe zuzuführende Schmierölmenge individuell einstellen zu können.In the upper region of the cylinder insert 1, a series of lubricating oil bores 5 are provided which penetrate the cylinder insert and end in a plane lying essentially perpendicular to the longitudinal axis of the cylinder insert on the lateral surface 1 '. The area in which the lubricating oil bores 5 are arranged lies below the uppermost piston ring 3 when the piston 2 is in its top dead center position. The limits of this range are between 5 and 18% of the piston stroke. Below the lubrication area formed in this way there is a second row of lubrication oil bores 6, which likewise end in a plane at right angles to the longitudinal axis of the cylinder insert 1 in the lateral surface. The second lubrication area formed by these lubricating oil bores 6 has its limits between 20 and 40% of the piston stroke. The lubricating oil holes 5 and 6 open into lubricating grooves 5 'and 6', which in the inner lateral surface 1 ' Cylinder insert 1 are incorporated and extend transversely to the direction of movement of the piston 2. A separate lubricating oil supply 7 or 8 is connected to each row of the lubricating oil bores 5 and 6 and each of these contains an adjusting element 9 or 10 in order to be able to individually adjust the amount of lubricating oil to be supplied to the associated row of lubricating oil holes.

Mit der beschriebenen Anordnung ist es z.B. möglich, sowohl der Reihe von Schmierölbohrungen 5 als auch der Reihe von Schmierölbohrungen 6 je 50 % des selben Schmieröls zuzuführen. Es ist aber auch möglich, der oberen Reihe 30 % und der unteren Reihe 70 % der gesamten Schmierölmenge zuzuführen. Andererseits ist es auch möglich, den beiden Schmierölbohrungsreihen verschiedene Schmierölsorten zuzuführen, z.B. derart, dass der oberen Reihe ein teureres Schmieröl mit einer hohen TBN zuge­führt wird und dass der unteren Schmierölbohrungsreihe ein billigeres Schmieröl mit einer niedrigeren TBN oder einer höheren Viskosität zugeführt wird.With the arrangement described it is e.g. possible to supply both the row of lubricating oil holes 5 and the row of lubricating oil holes 6 each 50% of the same lubricating oil. However, it is also possible to add 30% of the total amount of lubricating oil to the upper row and 70% to the lower row. On the other hand, it is also possible to supply different types of lubricating oil to the two rows of lubricating oil holes, e.g. such that a more expensive lubricating oil with a high TBN is fed to the upper row and a cheaper lubricating oil with a lower TBN or a higher viscosity is fed to the lower lubricating oil hole row.
