The lubricant oil is conveyed from the oil suction space to an oil supply container (wet sump) via an oil return pump equipped with an oil suction line. The lubricant oil in the oil supply tank and/or in the oil supply space is conveyed to the consumer via a main delivery pump. An annular space arranged around the cylinder is provided as part of the oil returned to the oil supply tank.

Description

Die Erfindung betrifft eine Brennkraftmaschine mit Druckumlaufschmierung nach dem Trockensumpfprinzip, insbesondere für einen Boxermotor z.B aus Dokument DE 10053096 und nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an internal combustion engine with pressure circulation lubrication on the dry sump principle, in particular for a boxer engine eg from document DE 10053096 and according to the preamble of claim 1.

Bei den heutigen wassergekühlten 6 - Zylinder - Boxermotoren der Modellreihe 911 Carrera (Firma Dr. Ing. h.c. F. Porsche AG) ist im Ölführungsgehäuse bzw. in der Ölwanne ein am Ölwannendeckel befestigter Ölschottkasten vorgesehen, in dem der Ölsumpf für die Schmierölversorgung des Motors ausgebildet ist. Das von den Verbrauchern in die Ölwanne zurückgeführte Schmieröl wird zuerst außerhalb des den Ölabsaugraum bildenden Ölschottkastens zurückgeleitet, bevor es über im Ölschottkasten durch Klappen überwachte Öffnungen in den eigentlichen Ölabsaugraum übertritt.In today 's water - cooled 6 - cylinder boxer engines of the 911 Carrera model series (Dr. Ing. Hc F. Porsche AG), an oil sump box attached to the sump cover is provided in the oil guide housing or in the oil sump, in which the oil sump is designed to supply the engine with lubricating oil is. The returned by the consumers in the oil pan lubricating oil is first returned outside of the Ölabsaugraum forming oil pan box before it passes through the monitored in Ölschottkasten by flaps openings in the actual Ölabsaugraum.

Bei Motoren mit Trockensumpfschmierung wird das in die Ölwanne zurückfließende Öl von einer Absaugpumpe in einen gesonderten Öltank bzw. Ölvorratsbehälter gefördert z.B aus Dokument US 4 825 825 . Von dort saugt die Druckölförderpumpe das Schmiermittel ab und drückt es über Filter und gff. Ölkühler zu den Schmierstellen. Der Öltank ist dabei in den meisten Fällen aussen am Motorgehäuse befestigt und verfügt über entsprechende Anschlüsse für die extern verlegten Öldruckleitungen.In motors with dry sump lubrication, the oil flowing back into the oil sump is conveyed by a suction pump into a separate oil tank or oil reservoir, eg from the document US 4,825,825 , From there, the pressure oil feed pump sucks off the lubricant and pushes it over the filter and gff. Oil cooler to the lubrication points. The oil tank is in most cases attached to the outside of the engine housing and has appropriate connections for the externally installed oil pressure lines.

Der Erfindung liegt die Aufgabe zugrunde, zur Steigerung der spezifischen Leistung einer Brennkraftmaschine ein reibungsarmes Triebwerk mit einer Trockensumpf - Druckumlaufschmierung insbesondere für den Hochdrehzahlbetrieb zu entwickeln, bei der die für die Druckumlaufschmierung der Brennkraftmaschine erforderlichen Komponenten auf platzsparende Art und Weise weitgehend im Motor integriert sind.The invention has for its object to increase the specific performance of an internal combustion engine to develop a low-friction engine with a dry sump - pressure circulation lubrication especially for high speed operation, in which the components required for the pressure circulation lubrication of the engine components are integrated in a space-saving manner largely in the engine.

Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved with the features of claim 1.

Erfindungsgemäß wird vorgeschlagen, dass ein Teil der Ölrückführung in den Ölvorratsbehälter bzw. in den Nasssumpfraum über Ringräume erfolgt, die um die Zylinder herum ausgebildet sind.According to the invention, it is proposed that a part of the oil return into the oil reservoir or into the wet sump space takes place via annular spaces which are formed around the cylinders.

Weitere Vorteile und vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen und der Beschreibung.Further advantages and advantageous embodiments of the invention will become apparent from the dependent claims and the description.

Insbesondere bei Zylinderkurbelgehäusen in open-deck- Bauweise, bei denen der Wassermantel nur im oberen Teil der Zylinder ausgebildet ist, verbleibt ein zum Kurbelgehäuseraum hin offener Ringraum, der bei entsprechender stirnseitiger Abdichtung als Teil der Ölrückführleitung in den Nasssumpf genutzt werden kann. Als Abdichtung des Ringraumes bietet sich dabei z.B. eine Brille aus Kunststoff an.In particular, in cylinder crankcases in open-deck construction, in which the water jacket is formed only in the upper part of the cylinder remains an open towards the crankcase chamber annular space, which can be used with appropriate frontal seal as part of the oil return line in the wet sump. As a seal of the annulus offers itself, for example a pair of plastic glasses.

Wenn der (Nasssumpf-) Ölsammelraum unterhalb der für die Ölrückführung vorgesehenen Ringräume angeordnet bzw. im Kurbelgehäuse integriert ist, kann das Schmieröl von den Ringräumen direkt in den bzw. die Ölsammelräume übertreten. Damit kann weitgehend auf externe Ölleitungen verzichtet werden, so dass diese Maßnahme zu einer kompakten und preisgünstigen Umsetzung einer Brennkraftmaschine mit Trockensumpfschmierung beiträgt.If the (wet sump) oil collecting space is arranged below the annular spaces provided for the oil return or integrated in the crankcase, the lubricating oil from the annular spaces can pass directly into the oil collecting space (s). This can largely be dispensed with external oil lines, so that this measure contributes to a compact and inexpensive implementation of an internal combustion engine with dry sump lubrication.

Aufgrund der bei einem Boxer- Motor liegend angeordneten Zylinder können die zur Schmierölrückführung dienenden Ringräume nach oben hin entlüftet und das Schmieröl entschäumt werden.Due to the cylinders arranged horizontally in a boxer engine, the annular spaces used for lubricating oil return can be vented upwards and the lubricating oil defoamed.

Ein Ausführungsbeispiel der Erfindung ist in der nachfolgenden Beschreibung und Zeichnung näher erläutert.An embodiment of the invention is explained in more detail in the following description and drawings.

Figur 1 zeigt das nicht auf diese Ausführungsform eingeschränkte Prinzip eines Trockensumpf - Ölkreislaufschemas für einen 6-Zylinder- Boxermotor, dessen lediglich zur Beschreibung des Ölkreislaufs erforderlichen Bauteile nachfolgend anhand der Zeichnungen näher beschrieben sind. Der Motor weist zwei Kurbelgehäusehälften 2 und 4 auf, in denen jeweils eine Zylinderbankreihe 1 bis 3 und 4 bis 6 angeordnet ist. An die beiden Zylinderbankreihen schließt sich jeweils ein Zylinderkopf 6 und 8 an, in denen der zum Betätigen der Ein- und Auslassventile erforderliche Ventiltrieb angeordnet ist. Das Kurbelgehäuse 2, 4 weist unterhalb der Lagerung für die Kurbelwelle 10 einen (Trockensumpf-) Ölabsaugraum 12 auf, in dem das zur Schmierung der Lagerstellen vorgesehene Schmieröl aufgefangen wird. Dabei stellen im Motor integrierte Ölrücklaufbohrungen (nicht dargestellt) sicher, dass das Schmieröl zielgerichtet in den Ölabsaugraum 12 zurückführt wird. FIG. 1 shows the not limited to this embodiment principle of a dry sump - oil circuit diagram for a 6-cylinder boxer engine whose only necessary for the description of the oil circuit components are described below with reference to the drawings. The engine has two crankcase halves 2 and 4, in each of which a row of cylinder banks 1 to 3 and 4 to 6 is arranged. To the two rows of cylinder banks is followed in each case by a cylinder head 6 and 8, in which the valve gear required for actuating the inlet and outlet valves is arranged. The crankcase 2, 4 has below the bearing for the crankshaft 10 to a (dry sump) Ölabsaugraum 12, in which the lubrication oil provided for the lubrication of the bearings is collected. In this case, integrated in the engine oil return holes (not shown) ensure that the lubricating oil is purposefully returned to the Ölabsaugraum 12.

Der Trockensumpf- Ölabsaugraum 12 wird durch einen Ölschottkasten 14 begrenzt, an dessen beiden Seitenwände 14a und 14b (Nasssumpf-) Sammelräume 16 und 18 angrenzen. Beide Sammelräume 16, 18 stehen über einen zwischen der unteren Wandung 14c des Ölschottkastens 14 und einem Ölwannendeckel 20 sich ausbildenden Zwischenraum 22 miteinander in Verbindung. Für die Trockensumpf-Druckumlaufschmierung ist eine Ölrückförderpumpe 24 vorgesehen, an deren Saugseite eine Ölabsaugleitung 26 angeschlossen ist, die in den Ölabsaugraum 12 führt. Am Ende der Ölabsaugleitung 26 ist ein Ölabsaugschnorchel 28 befestigt, der im Bereich der unteren Wandung 14c des Ölschottkastens 14 platziert ist. An der Druckseite der Ölrückförderpumpe 24 ist eine Leitung 30 angeschlossen, die als Abzweigleitung 30a bzw. 30b zu jeweils einem die Zylinder 1 bis 3 sowie 4 bis 6 umgebenden Ringraum 32 und 34 führt.The Trockensumpf- Ölabsaugraum 12 is bounded by an oil bulkhead 14, on the two side walls 14a and 14b (wet sump) collecting spaces 16 and 18 adjacent. Both collecting chambers 16, 18 are connected to each other via a between the lower wall 14c of the oil pan 14 and a sump cover 20 forming gap 22 with each other. For dry sump pressure circulation lubrication an oil return pump 24 is provided, on whose suction side an oil suction line 26 is connected, which leads into the Ölabsaugraum 12. At the end of the Ölabsaugleitung 26 an Ölabsaugschnorchel 28 is attached, which is placed in the region of the lower wall 14 c of the oil pan 14. On the pressure side of the oil return pump 24, a line 30 is connected, which leads as a branch line 30a and 30b to a respective cylinder 1 to 3 and 4 to 6 surrounding annular space 32 and 34.

Die beiden Ringräume 32, 34 sind jeweils an ihrer dem Kurbelraum zugewandten Stirnseite durch eine Dichtung 36 (nur in der linken Kurbelgehäusehälfte 2 dargestellt), z.B. in Form einer Kunststoffbrille, abgedichtet. Wie aus Fig. 1 und 2 erkennbar, weisen die Ringräume 32, 34 an ihren unteren Mantelflächen Öffnungen 38 bzw. Durchbrüche auf, die jeweils mit den (Nasssumpf-) Sammelräumen 16, 18 in Verbindung stehen. Der mittlere Zylinder der beiden Zylinderbankreihen 1 bis 3 bzw. 4 bis 6 weist jeweils einen Entlüftungsstutzen 40, 42 auf, der auf der -bezogen auf die Einbaulage der Zylinderoberen Seite der Ringräume 32, 34 angeschlossen ist. Aufgrund dieser Form der Ölrückführung kann weitgehend auf extern verlegte Ölleitungen verzichtet werden; über die Ringräume 32, 34 kann das Schmieröl entschäumt und Luft- bzw. Gasanteile über die Entlüftungsstutzen 40, 42 nach außen abgeführt werden, so dass auf separate Öl/Luftabscheider verzichtet werden kann. Wie in Fig. 1 dargestellt, werden die Nasssumpf- Sammelräume 16, 18 und der Trockensumpf- Ölabsaugraum 12 über entsprechende Leitungen 54, 56 entlüftet. Im oberen Bereich der Zylinder sind ebenfalls Ringräume 55 ausgebildet, die zur Kühlung der Zylinder mit Kühlmittel durchströmt und durch einen umlaufenden Steg 57 von den Ringräumen 32, 34 getrennt sind.The two annular spaces 32, 34 are each at their crankcase facing end face by a seal 36 (shown only in the left crankcase half 2), eg in the form of plastic glasses, sealed. How out Fig. 1 and 2 recognizable, the annular spaces 32, 34 on their lower lateral surfaces openings 38 and openings, which are in each case with the (wet sump) collecting spaces 16, 18 in combination. The middle cylinder of the two rows of cylinder banks 1 to 3 or 4 to 6 each have a vent pipe 40, 42 which is connected to the -related to the installation position of the cylinder top side of the annular spaces 32, 34. Due to this form of oil return can largely be dispensed with externally routed oil lines; The lubricating oil can be defoamed via the annular spaces 32, 34 and air or gas fractions can be discharged to the outside via the ventilation stubs 40, 42, so that separate oil / air separators can be dispensed with. As in Fig. 1 illustrated, the wet sump plenums 16, 18 and the Trockensumpf- Ölabsaugraum 12 via corresponding lines 54, 56 are vented. In the upper region of the cylinder annular spaces 55 are also formed, which flows through to cool the cylinder with coolant and are separated by a circumferential ridge 57 of the annular spaces 32, 34.

In den beiden Zylinderköpfen 6, 8 der Brennkraftmaschine sind von den Nockenwellen angetriebene Absaugpumpen 44, 46 vorgesehen, die das von einer Hauptförderpumpe 48 in die Zylinderköpfe 6, 8 geförderte Schmieröl absaugen und es über Leitungen 50, 52 und die Ringräume 32, 34 ebenfalls in die (Nasssumpf-) Sammelräume 16, 18 zurückführen.In the two cylinder heads 6, 8 of the internal combustion engine driven by the camshafts suction pumps 44, 46 are provided which suck the pumped from a main pump 48 into the cylinder heads 6, 8 lubricating oil and via lines 50, 52 and the annular spaces 32, 34 also in the (wet sump) collecting spaces 16, 18 return.

Die Hauptförderpumpe 48 wird über eine Zwischenwelle (nicht näher dargestellt) angetrieben, an deren Saugseite eine Ölabsaugleitung 58 angeschlossen ist, die in den Ölsammelraum 16 führt. Am Ende der Ölabsaugleitung 58 ist wiederum ein Ölabsaugschnorchel 60 befestigt, der in der Nähe des Ölwannendeckels 20 platziert ist. An die Druckseite der Hauptförderpumpe 48 sind im Kurbelgehäuse 2, 4 integrierte Ölzufuhrleitungen (nicht näher dargestellt) angeschlossen, die zu den Verbrauchern, wie z.B. Hauptlagerstellen der Kurbelwelle und der Nockenwelle, führen.The main feed pump 48 is driven via an intermediate shaft (not shown in detail), on whose suction side an oil suction line 58 is connected, which leads into the oil collecting space 16. At the end of the oil suction line 58, an oil suction snorkel 60 is again attached, which is placed in the vicinity of the sump cover 20. To the pressure side of the main feed pump 48 are integrated in the crankcase 2, 4 integrated oil supply lines (not shown) connected to the consumers, such as. Main bearings of the crankshaft and the camshaft lead.
