Abstract

The internal combustion engine has a continuous oil dipstick channel (9) for holding the dipstick (17) leading from the cam shaft conductor frame (5) to the oil sump (6). This dipstick channel also forms the oil return channel and can be mounted on the inlet or outlet side of the engine.

Description

Die Erfindung betrifft eine Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1.The The invention relates to an internal combustion engine according to the preamble of claim 1.

In Brennkraftmaschinen allgemein, d.h. sowohl in Otto- als auch in Dieselmotoren, ist es üblich im unteren Bereich des Kurbelgehäuses ein sich nach oben erstreckendes, externes Führungsrohr vorzusehen, das zur Aufnahme eines Ölmeßstabs dient. Hierdurch bedingt sind auch zusätzliche Dichtstellen am Grundmotor sowie daran erforderliche Bearbeitungsschritte.In Internal combustion engines in general, i. both in petrol and in Diesel engines, it is common in the lower portion of the crankcase to provide an upwardly extending, external guide tube, the serves to receive a Dipstick. This also requires additional Sealing points on the base engine as well as necessary processing steps.

Aufgabe der Erfindung ist es, eine Brennkraftmaschine nach dem Oberbegriff des Anspruchs 1 zu schaffen, bei der der Aufwand für das Vorsehen eines Ölmeßstabs erheblich verringert ist.task The invention is an internal combustion engine according to the preamble of claim 1, wherein the cost of providing an oil dipstick considerably is reduced.

Diese Aufgabe wird entsprechend der Merkmalskombination des Anspruchs 1 gelöst.These Task is according to the combination of features of the claim 1 solved.

Hierbei ist vorgesehen, daß von der Oberseite des Nockenwellenleiterrahmens ein durchgehender Ölmeßstabkanal bis zur Ölwanne vorgesehen ist, der den Ölmeßstab aufnimmt. Insbesondere ist es zweckmäßig, wenn der Ölmeßstabkanal zugleich der Ölrücklaufkanal ist. Hierdurch entfallen Dicht- und Verschraubungselemente sowie Bearbeitungsschritte am Grundmotor. Außerdem ist durch diese Positionierung im Nockenwellenleiterrahmen die leichte Zugänglichkeit des Ölmeßstabes im Fahrzeug immer gewährleistet. Ein externes Führungsrohr wird vermieden und es können ohnehin bereits in der Brennkraftmaschine vorhandene Öffnungen genutzt werden.in this connection is provided that of the top of the cam lead frame a continuous Ölmeßstabkanal to the oil pan is provided, which receives the dipstick. In particular, it is expedient if the dipstick channel at the same time the oil return channel is. This eliminates sealing and screwing as well Processing steps on the base motor. In addition, this positioning is in the camshaft frame the easy accessibility of the dipstick always guaranteed in the vehicle. An external guide tube is avoided and it can already existing in the internal combustion engine openings be used.

Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen.Further Embodiments of the invention are the following description and the dependent claims refer to.

Die Erfindung wird nachstehend anhand eines in der beigefügten Abbildung dargestellten bevorzugten Ausführungsbeispiels näher erläutert, wobei die Abbildung eine Brennkraftmaschine ausschnittweise im Schnitt zeigt.The Invention will be described below with reference to an attached drawing illustrated preferred embodiment explained in more detail, wherein the picture of an internal combustion engine in sections on average shows.

Die dargestellte Ausführungsform einer Brennkraftmaschine umfaßt ein Kurbelgehäuse 1 und einen darunter befindlichen Leiterrahmen 2, die eine nicht dargestellte Kurbelwelle lagern. Letztere steht mit in Zylindern des Kurbelgehäuses 1 geführten Kolben in Wirkverbindung. Auf dem Kurbelgehäuse 1 ist ein Zylinderkopf 3 befestigt, der Ventile und wenigstens eine die Ventile betätigende Nockenwelle 4 aufnimmt und von einem Nockenwellenleiterrahmen 5 abgedeckt ist. An der Unterseite des Leiterrahmens 2 ist eine Ölwanne 6 befestigt.The illustrated embodiment of an internal combustion engine comprises a crankcase 1 and a ladder frame underneath 2 , which store a crankshaft, not shown. The latter is in cylinders of the crankcase 1 guided piston in operative connection. On the crankcase 1 is a cylinder head 3 attached, the valves and at least one valve actuating camshaft 4 picks up and from a cam guide frame 5 is covered. At the bottom of the ladder frame 2 is an oil pan 6 attached.

Die Brennkraftmaschine besitzt einen Ölkreislauf umfassend eine in diesem Fall am Leiterrahmen 2 befindliche Ölpumpe 7 mit einem Ölsaugrohr 8 (schematisch angedeutet) zum Fördern von Öl aus dem Ölvorrat der Ölwanne in den Motorbereich und einen Ölrücklaufkanal 9, der sich vom Zylinderkopf 3 über die Höhe des gesamten Kurbelgehäuses 1 und des Leiterrahmens 2 erstreckt. Der Ölrücklaufkanal 9 mündet im Zylinderkopf 3 in einen Freiraum 10. Der Nockenwellenleiterrahmen 5 umfaßt eine Ventildeckelhaube 11 und eine Deckplatte hierfür, wobei die Ventildeckelhaube 11 eine Durchtrittsöffnung 13 aufweist, die im Bereich eines Stutzens 14 des Nockenwellenleiterrahmens 5 mündet. Der Stutzen 14 nimmt das mit einem Fingerring 15 versehene Kopfstück 16 eines Ölmeßstabs 17 auf, der sich durch die Durchtrittsöffnung 13, den Freiraum 10 vorbei an der Nockenwelle 4, den Ölrücklaufkanal 9 bis in die Ölwanne 6 erstreckt. Kanten wie die Kante 18 sind hierbei entsprechend gerundet, so daß sie ein Einstecken des Ölmeßstabs 17 nicht behindern.The internal combustion engine has an oil circuit comprising in this case the lead frame 2 located oil pump 7 with an oil suction pipe 8th (indicated schematically) for conveying oil from the oil reservoir of the oil pan in the engine area and an oil return passage 9 that is different from the cylinder head 3 about the height of the entire crankcase 1 and the ladder frame 2 extends. The oil return channel 9 flows into the cylinder head 3 in a free space 10 , The camshaft frame 5 includes a valve cover hood 11 and a cover plate therefor, wherein the valve cover 11 a passage opening 13 that is in the area of a nozzle 14 of the camshaft frame 5 empties. The stub 14 take that with a finger ring 15 provided head piece 16 an oil dipstick 17 on, extending through the passage opening 13 , the free space 10 past the camshaft 4 , the oil return channel 9 to the oil pan 6 extends. Edges like the edge 18 are rounded accordingly, so that they plug in the dipstick 17 do not hinder.

Am Leiterrahmen 2 kann ein das sich in den Bereich der Ölwanne 6 erstreckende Ende des Ölmeßstabs 17 umgebendes Schutzrohr 19 vorgesehen sein. Der Freiraum 10 kann bis zum Stutzen 14 durch ein den Ölmeßstab 17 führendes Schutzrohr 20 überbrückt sein.On the ladder frame 2 can be an in the area of the oil pan 6 extending end of Ölmeßstabs 17 surrounding protective tube 19 be provided. The open space 10 can up to the neck 14 through an oil dipstick 17 leading protection tube 20 be bridged.

Der Ölmeßstab 17 kann sowohl auf der Einlaßseite als auch auf der Auslaßseite der Brennkraftmaschine angeordnet sein.The dipstick 17 can be arranged both on the inlet side and on the outlet side of the internal combustion engine.

Auf diese Weise wird eine Brennkraftmaschine geschaffen, bei der ein durchgehender Kanal 9 für einen Ölmeßstab 17 innerhalb der Brennkraftmaschine vorgesehen ist, der an deren Oberseite mündet und bis zur Ölwanne 6 reicht.In this way, an internal combustion engine is created in which a continuous channel 9 for an oil dipstick 17 is provided inside the internal combustion engine, which opens at the top and to the oil pan 6 enough.
