Abstract
Description
Die Erfindung betrifft einen Verbrennungsmotor, insbesondere stationärer Gasmotor, mit einem Kolben, der in einer Zylinderbüchse läuft, welche innerhalb des Kurbelgehäuses angeordnet ist und welche im Bereich ihres oberen, dem Zylinderkopf benachbarten Randes einen Ringflansch zur Abstützung im Kurbelgehäuse in axialer Richtung aufweist, mit einem auf der Außenseite der Zylinderbüchse verlaufenden Kühlflüssigkeitskanal und mit einem an der Innenseite der Zylinderbüchse im Bereich ihres oberen Randes angeordneten etwas über die Innenfläche der Zylinderbüchse vorspringenden Schabering zur Abschabung der Außenseite des Kolbens im an die Stirnfläche des Kolbens angrenzenden Bereich.The invention relates to an internal combustion engine, in particular a stationary gas engine a piston that runs in a cylinder liner, which is inside the crankcase is arranged and which in the region of its upper edge adjacent to the cylinder head has an annular flange for support in the crankcase in the axial direction, with a on the outside of the cylinder liner running coolant channel and with a the inside of the cylinder liner in the area of its upper edge Scraper ring projecting over the inner surface of the cylinder liner for scraping the Outside of the piston in the area adjacent to the end face of the piston.
Ein Verbrennungsmotor dieser Art ist bereits bekannt. Der Schabering dieses Verbrennungsmotors verhindert, die Ablagerung von Verbrennungsrückständen an der Außenseite des Kolbens im an die Stirnfläche des Kolbens angrenzenden Bereich, welche anderenfalls im Laufe der Zeit insbesondere zur Beeinträchtigung der Funktion der Kolbenringe führen können.An internal combustion engine of this type is already known. The scraper ring this Internal combustion engine prevents the deposition of combustion residues on the Outside of the piston in the area adjacent to the end face of the piston, which otherwise in the course of time in particular to impair the function of the piston rings being able to lead.
Aufgabe der Erfindung ist es, einen Verbrennungsmotor bereitzustellen, bei dem die Betriebszuverlässigkeit und Lebensdauer gegenüber den bekannten Motoren dieser Art verbessert wird. Erfindungsgemäß gelingt dies dadurch, daß der auf der Außenseite der Zylinderbüchse verlaufende Kühlflüssigkeitskanal bis zum Ringflansch geführt ist und daß der Schabering und die Zylinderbüchse aus dem gleichen Material bestehen.The object of the invention is to provide an internal combustion engine in which the Operational reliability and service life compared to the known motors of this type is improved. According to the invention this is achieved in that the on the outside of the Cylinder sleeve extending coolant channel is guided to the ring flange and that the scraper ring and the cylinder liner are made of the same material.
Zur Lösung der erfindungsgemäßen Aufgabe würde es für einen Fachmann zunächst naheliegen, den Schabering aus einem möglichst harten Material herzustellen, welches sich somit vom Material der Zylinderbüchse unterscheiden wird. Der Grundgedanke der Erfindung besteht demgegenüber darin, daß es sich beim erfindungsgemäßen Problem in erster Linie nicht um ein mechanisches, sondern um ein thermisches Problem handelt. Durch thermische Spannungen kann es nämlich im Laufe der Zeit zu einem Verzug bzw. zu einer Lockerung des Schaberinges kommen. Um dem entgegenzuwirken, sind die erfindungsgemäßen Maßnahmen vorgesehen.For a person skilled in the art, it would initially solve the object of the invention obvious to make the scraper ring from the hardest possible material, which is thus differentiate from the material of the cylinder liner. The basic idea of In contrast, the invention is that it is in the problem of the invention is primarily not a mechanical problem, but a thermal one. Thermal stresses can cause a delay or over time a loosening of the scraper ring. To counteract this, they are Measures according to the invention are provided.
Obwohl stationäre Gasmotoren standardmäßig entsprechend der nachfolgend beschriebenen Fig. 1 konstruiert sind, sind aus der DE 34 13 971 A1 und der GB 1 478 379 A spezielle Motoren bekannt, bei denen der auf der Außenseite der Zylinderbüchse verlaufende Kühlfüssigkeitskanal ebenfalls bis zum Ringflansch der Zylinderbüchse geführt ist. Da diese Motoren keinen Schabering aufweisen, dient diese Maßnahme hier allerdings nicht zum gleichen Zweck wie bei der Erfindung, nämlich die thermischen Spannungen zwischen Schabering und Zylinderbüchse zu vermindern. Erst durch die Kombination dieses Merkmals mit dem Merkmal, daß der Schabering und die Zylinderbüchse aus dem gleichen Material bestehen, wird ein besonders betriebs- und ausfallsicherer Verbrennungsmotor mit Schabering bereitgestellt.Although stationary gas engines are standard according to the following 1 are constructed from DE 34 13 971 A1 and GB 1 478 379 A special engine is known where the one on the outside of the cylinder liner running coolant channel also led to the ring flange of the cylinder liner is. Since these motors do not have a scraper ring, this measure is used here not for the same purpose as in the invention, namely the thermal stresses between the scraper ring and cylinder liner. Only by combining this Feature with the feature that the scraper ring and the cylinder liner from the same Material, a particularly operational and fail-safe internal combustion engine Scraper ring provided.
Weitere Vorteile und Einzelheiten der Erfindung werden im folgenden anhand der
beiliegenden Zeichnung erläutert. In dieser zeigen
Der in Fig. 1 gezeigte Ausschnitt eines Zylinders des Standes der Technik wie er bei
stationären Gasmotoren verwendet wird, weist einen Kolben 110 auf, der in einer
Zylinderbüchse 101 läuft. Die Zylinderbüchse weist im Bereich ihres oberen dem
Zylinderkopf 102 benachbarten Randes 103 einen Ringflansch 104 auf. Dieser Ringflansch
104 dient zur axialen Abstützung der Zylinderbüchse am Kolbengehäuse 105, welche über
den Zylinderkopf 102 in axialer Richtung beaufschlagt ist. Zwischen Ringflansch 104 der
Zylinderbüchse 101 und Zylinderkopf 102 liegt die Zylinderkopfdichtung 106 und im
Zylinderkopf 102 ist in dieser Schnittdarstellung eines der Ventile 107 sichtbar. Die
Zentrierung der Zylinderbüchse 101 im Kurbelgehäuse 105 erfolgt im Bereich 108 kurz
unterhalb des Ringflansches 104. Zwischen Kurbelgehäuse 105 und Zylinderbüchse 101
erstreckt sich bis zu diesem Bereich 108 ein Kühlflüssigkeitskanal 109.The section shown in Fig. 1 of a cylinder of the prior art as in
stationary gas engines is used, has a piston 110 which in a
Anhand der Fig. 2, welche ebenfalls einen Teil eines Längsschnittes durch einen Zylinder
eines größeren Motors, insbesondere eines stationären Gasmotors, darstellt, soll nun die
Erfindung erläutert werden. Da ein Schnitt quer zur Richtung der Verbindungslinie zwischen
den im Zylinderkopf 2 angeordneten Ventilen dargestellt ist, sind die (dem Stand der Technik
entsprechenden) Ventile in dieser Fig. nicht sichtbar. Wiederum läuft der Kolben 10 in einer
Zylinderbüchse 1, welche innerhalb des Kurbelgehäuses 5 angeordnet ist. Im Bereich des
oberen Randes 3 der Zylinderbüchse 1 ist diese mit einem Ringflansch 4 versehen, über
welchen sie sich in axialer Richtung im Kurbelgehäuse 5 an einem Flansch 11 abstützt. In
diese axiale Richtung wird die Zylinderbüchse 1 vom Zylinderkopf 2 beaufschlagt, wobei
zwischen Zylinderkopf und Zylinderbüchse die Zylinderkopfdichtung 6 angeordnet ist. Die
Zentrierung der Zylinderbüchse 1 im Kurbelgehäuse 5 erfolgt im Gegensatz zu dem in Fig. 1
gezeigten Zylinder des Standes der Technik an der Außenseite 12 des Ringflansches 4, der
in einer entsprechenden Ausnehmung im Kurbelgehäuse 5 liegt. Der Kühlflüssigkeitskanal 9
reicht erfindungsgemäß bis zum Ringflansch 4 der Zylinderbüchse 1. Dadurch wird die
Kühlung des oberen Bereiches der Zylinderbüchse wesentlich verbessert.2, which is also part of a longitudinal section through a cylinder
of a larger engine, especially a stationary gas engine, is now the
Invention are explained. Because a cut across the direction of the connecting line between
The valves arranged in the
In diesem oberen Bereich der Zylinderbüchse 1 ist ein an ihrer Innenseite angeordnete
Schabering 13 vorgesehen, der etwas über die Innenfläche 14 der Zylinderbüchse 1 vorspringt.
Dieser besteht aus dem gleichem Material wie die Zylinderbüchse, da andernfalls zu
starke thermische Verspannungen zwischen Schubring 13 und Zylinderbüchse 1 auftreten
würden. Damit der Rand der Stirnfläche 15 des Kolbens 10 bei dessen Aufwärtsbewegung
nicht frontal auf die Unterkante des Schaberinges 13 aufprallen kann, verjüngt sich der
Kolben 10 in seinem Bereich oberhalb der Nut 17, in der der oberste Kolbenring (nicht
eingezeichnet) liegt. Durch den Schabering 13 wird eine Anlagerung von Verbrennungsrückständen
an der Außenseite 16 des Kolbens 10 im an die Stirnfläche 15 angrenzenden
Bereich verhindert. Durch die verbesserte Kühlung des oberen Bereiches der Zylinderbüchse
1, in welchem der Schabering 13 angeordnet ist, werden die thermischen
Spannungen verringert und ein sicherer Sitz des Schaberinges 13 in der Zylinderbüchse 1
wird gewährleistet.In this upper area of the cylinder liner 1 there is an inner one
