Definitions
- the invention relates to an internal combustion engine, with a cylinder crankcase delimiting a crankcase and a lubricant sump receiving a lubricant sump, which has a lubricant sump upper part arranged between the crankcase and the lubricant sump and a lubricant sump lower part attached to the lubricant sump upper part, with several of a basic component of the lubricant sump upper part Struts extend in the direction of the lubricant sump, which partially intersect and thereby form chambers closed at the edge between them in section, and with lubricant passage openings formed in at least some of the chambers in the upper part of the lubricant pan, via which the crank chamber and the lubricant sump are in flow connection.
- Document EP 2 039 895 B1 is known from the prior art.
- This describes a structural oil pan for an internal combustion engine, provided with an upper opening and having an element made of plastic, which has several side walls that delimit an interior space around, at least one transverse part which extends in said interior space in such a way that it connects at least two of the side walls to one another.
- the element made of plastic is an upper element which is formed in one piece with the transverse part, the upper element being located between an upper end which defines said upper opening and a lower end which defines a lower opening, it stretches, and that the tub has a lower element which has a bottom and is sealingly attached to the lower end of the upper element, said upper member having internal ribs arranged opposite one another with respect to the bottom.
- the object of the invention is to propose an internal combustion engine which has advantages over known internal combustion engines, in particular losses of the internal combustion engine achieved by a lower lubricant level in the crankcase.
- the internal combustion engine is, for example, part of a motor vehicle, but can also be present separately from it.
- the internal combustion engine is preferably used to drive the motor vehicle, so to the extent that it is ready to provide a drive torque aimed at driving the motor vehicle.
- the internal combustion engine has the cylinder crankcase in which the crank chamber is formed.
- crankshaft of the internal combustion engine is rotatably mounted about an axis of rotation in the crank chamber.
- the bearing journals are arranged coaxially to the axis of rotation of the crankshaft.
- the crankshaft has crank pins which are arranged eccentrically with respect to the bearing pin or the crankshaft.
- crank pins are connected to the bearing pins via cheeks.
- Pistons of the internal combustion engine are connected to the crankshaft via the crank pin.
- a connecting rod is rotatably mounted on the one hand on the crank pin and on the other hand rotatably on the piston.
- the col- ben are in turn mounted linearly displaceably in cylinders, the cylin which are formed in the cylinder crankcase.
- the crank chamber in which the crankshaft is arranged is delimited by the lubricant sump in the direction facing away from the cylinders. This has at least the upper part of the lubricant tub and the lower part of the lubricant tub.
- the lubricant pan receives the lubricant sump, which is arranged between the lubricant pan upper part and the lubricant pan lower part.
- the top part of the lubricant pan is arranged between the bottom part of the lubricant pan and the cylinder crankcase.
- the upper part of the lubricant pan limits the lubricant sump in the direction of the crank chamber and the cure belraum in the direction of the lubricant sump.
- the upper part of the lubricant pan is attached directly to the cylinder crankcase and the lower part of the lubricant pan to the lubricant pan upper part. Accordingly, the top part of the lubricant tub is only attached indirectly to the cylinder crankcase via the top part of the lubricant tub. It can of course also be provided that both the lower part of the lubricant pan and the upper part of the lubricant pan are each fastened directly to the cylinder crankcase. It is only important that the top part of the lubricant tub, the bottom part of the lubricant tub and the cylinder crank housing are fixed against each other.
- lubricant is supplied to the crank chamber, in particular for lubrication and / or cooling, for example the crankshaft, the pistons, the connecting rods and / or bearings for supporting the crankshaft and / or the connecting rods. Air is drawn into the lubricant due to the moving parts in the crankcase.
- the lubricant introduced into the crankcase is forced in the direction of the lubricant sump by the influence of gravity, in particular into the lubricant sump.
- the lubricant first reaches the upper part of the lubricant tub, namely the side of the lubricant upper part facing the crankcase.
- the lubricant passage openings are formed, via which the crank chamber and the lubricant sump are in flow connection with one another.
- the lubricant flows through the lubricant passage openings from the crankcase into the lubricant sump.
- the lubricant is settled in the lubricant sump.
- the air present in the lubricant is separated from the lubricant.
- the lubricant which has now been freed from the air, can subsequently be removed again from the lubricant sump and fed to the crankcase.
- the lubricant is removed from the lubricant sump by means of a lubricant pump and again conveyed in the direction of the crank chamber or into the crank chamber.
- the lubricant is fed to a cylinder head and / or a camshaft actuator.
- the lubricant removed from the lubricant sump is preferably fed to a lubricant filter before it is fed to the crankcase, the cylinder head and / or the camshaft adjuster.
- the lubricant filter is used to separate dirt particles located in the lubricant.
- the upper part of the lubricant tub is designed like a framework. Accordingly, it has several webs that start from its basic component.
- the basic component be here bounds the crank chamber in the direction of the lubricant sump and the webs extend starting from the basic component in the direction of the lubricant sump, that is, in the direction facing away from the crank chamber.
- the webs partially intersect, in particular at least several of the webs are cut by each other of the webs, so that a chamber structure with several chambers is formed, which in the direction of the
- the lubricant sump are open. Seen in section, the webs thus enclose a plurality of chambers between them, which are delimited in the direction of the crank chamber by the basic component of the upper part of the lubricant tub. In the intended installation position of the internal combustion engine, the basic component thus forms a ceiling of the chambers.
- the first of the webs run in a first direction and the second of the webs in a second direction different from the first direction.
- the first webs run parallel to one another, for example, at least in some areas or continuously.
- the first direction is, for example, parallel to the axis of rotation of the crankshaft.
- the second webs run at an angle with respect to the first webs, so they each enclose an angle with them which is greater than 0 ° and less than 180 °.
- the second webs run parallel to one another.
- the second webs can, however, also be angled to one another if they are, or they can also be skewed to one another. It is therefore not necessary for the second webs to each enclose the same angle with the first webs. Rather, the angles can be different from one another.
- the webs each have on their side facing away from the basic component a free end which protrudes in the direction of the lubricant sump.
- at least one of the webs several of the webs or all of the webs extend at least almost as far as a contact surface of the lubricant tub upper part on which the lubricant tub lower part is supported, for example via a seal.
- the lower part of the lubricant tub preferably has a counter-contact surface which directly or indirectly rests against the contact surface of the upper part of the lubricant tub, for example via the named seal.
- the contact surface preferably lies continuously in an imaginary plane, which is in particular parallel to the axis of rotation of the crankshaft.
- the distance between the web, the multiple webs or all webs and the imaginary plane is preferably a maximum of 25%, a maximum of 20%, a maximum of 15%, a maximum of 10% or at most 5%.
- the web merges into the contact surface via a rounding, so that a particularly small distance is achieved between the web and the contact surface.
- the described configuration of the upper part of the lubricant tub with the chambers formed by the webs has the disadvantage that some of the air separated from the lubricant collects in the chambers and remains there. Accordingly, the capacity of the lubricant sump for the lubricant is reduced. This results in a comparatively high lubricant level in the crankcase. This can have the consequence that the crankshaft is periodically immersed in the lubricant located in the crankcase during operation of the internal combustion engine, so that the internal combustion engine is lost. The immersion also introduces more air into the lubricant, so that the problem is exacerbated.
- the at least one Vent opening is formed in the upper part of the lubricant pan.
- the Vent opening opens into the crankcase on the one hand and into one of the chambers on the other.
- a vent opening is provided and formed in each of the chambers, in which none of the lubricant passage openings opens.
- the ventilation openings are made small in comparison with the lubricant passage openings. designed. This is to be understood as meaning that they have a smaller flow cross-section, that is, their flow cross-section has a smaller flow cross-sectional area than the lubricant passage openings.
- a further development of the invention provides that the lubricant passage openings are formed in the walls of the upper part of the lubricant sump, delimiting the recesses that are open in the direction of the crankcase and spaced apart from one another, the recesses in the axial direction with respect to an axis of rotation of a crankshaft of the internal combustion engine in overlap with crank pins of the crankshaft are arranged.
- lubricant pan Under the walls, areas of the upper part of the lubricant pan are to be understood, which are preferably present on this at a distance from one another.
- the walls delimit the depressions in which lubricant collects during operation of the internal combustion engine and passes through the lubricant passage openings into the lubricant sump.
- the depressions can in this respect also be referred to as lubricant collection depressions.
- the depressions are seen in the axial direction with respect to the axis of rotation of the crankshaft in overlap with the crank pin of the crankshaft. This is to be understood as meaning that one of the depressions is arranged in overlap with each of the Hubzap fen. Conversely, one of the crank pins of the crank shaft is preferably arranged in overlap with each of the depressions.
- lubricant thrown away by the crankshaft gets directly into the depressions and can from there into the Lubricant sump are discharged.
- the upper part of the lubricant pan and in particular the walls therefore represent a “lubricant plane” of the internal combustion engine.
- crank pins of the crankshaft, the cheeks of the crankshaft and / or the connecting rods engage at least temporarily in the recesses during operation of the internal combustion engine.
- This achieves a particularly effective removal of the lubricant from the crank chamber in the direction of the lubricant sump.
- the depressions are, for example, designed in the manner of a torus, that is to say they preferably have the shape of a section on a torus.
- the torus is preferably to be understood as a rotational torus, which in turn is present as the body of revolution of a circle.
- a further development of the invention provides that the lubricant passage openings are present in two rows arranged parallel to one another and to the axis of rotation of the crankshaft, with fastening recesses being formed in the upper part of the lubricant pan, which are enclosed by the webs, between the two rows.
- the parallel arrangement of the rows to one another and to the axis of rotation of the crankshaft is to be understood as an at least approximately approximately parallel arrangement or an exactly parallel arrangement. In the first case there is an angle of at most 10 °, at most 5 ° or at most 2.5 °, for example, between the rows and / or one of the rows and the axis of rotation.
- each of the rows there are at least two of the lubricant passage openings.
- the fastening recesses are formed between the rows and extend completely through the basic component of the upper part of the lubricant tub.
- Each of the fastening recesses is preferably enclosed by the webs, for example one or more webs merge into an annular web for this purpose, which completely surrounds the respective fastening recess.
- Particularly preferably, several of the webs start from each of the ring webs. For example, the ring ridges bordered by two mutually parallel webs which rest against the ring webs or merge into the ring webs.
- the fastening recesses serve to accommodate fastening elements, for example screws or bolts, by means of which the upper part of the lubricant pan is attached, for example to the cylinder crankcase and / or the lower part of the lubricant pan.
- the central arrangement of the fastening recesses with respect to the lubricant passage openings enables a particularly rigid and low-vibration design of the upper part of the lubricant tub.
- a further development of the invention provides that in addition to the vent opening there is at least one further vent opening, a flow cross section of the further vent opening being larger than a flow cross section of the vent opening and smaller than the flow cross section of the lubricant passage openings.
- the at least one further vent opening is present in addition to the at least one vent opening. Just like the vent opening, it extends through the basic component of the upper part of the lubricant sump and connects the lubricant sump with the crankcase in terms of flow. In addition, it can be provided that it opens into one of the chambers.
- the further vent opening has a larger flow cross section than the vent opening.
- the flow cross-sectional area of the flow cross-section of the further vent opening is greater by a factor of at least 5, at least 7.5 or at least 10 than the flow cross-sectional area of the flow cross-section of the vent opening.
- the number of further ventilation openings is important less than the number of vents.
- the upper part of the lubricant tub has a factor of at least 2, at least 3, at least 4 or at least 5 more ventilation openings than wider ventilation openings.
- the lubricant passage openings are not round and the vent opening is round.
- the lubricant passage openings have an unround de shape.
- the lubricant passage openings are designed in the shape of a slot or a stadium. Of course, they can also be oval, for example elliptical.
- the lubricant passage openings reach through the respective recess in the axial direction with respect to the axis of rotation of the crankshaft to at least 70%, at least 80% or at least 90%.
- the vent is round in order to implement the least possible impairment of the stiffness of the upper part of the lubricant pan.
- the embodiment described thus enables both an effective discharge of the lubricant from the crankcase and an effective venting of the lubricant sump.
- vent opening is formed in a geodetically highest area of an area of the basic component that delimits the respective chamber in the installed position of the internal combustion engine.
- the area of the basic component forms appropriate installation position from the roof of the respective chamber. This roof is penetrated by the ventilation opening, namely at the geodä table at the highest point of the roof. A particularly effective venting of the chamber is achieved in this way.
- the ventilation opening is formed in one of the walls.
- the walls are to be understood as those areas of the upper part of the lubricant pan which delimit the depressions which are open in the direction of the crankcase and have been described above. This applies in particular if none of the lubricant passage openings opens into the chamber which is delimited by the wall in the direction of the crankcase.
- Such a chamber lies, for example, between the fastening recesses. The production of the vent opening in the wall delimiting the chamber ensures adequate ventilation at this point.
- a further development of the invention provides that the further vent opening has dimensions in a first direction which are at least 75% and / or at most 125% of the dimensions of one of the lubricant passage openings in the same direction and / or that the further vent opening in a perpendicular direction the second direction standing in the first direction has dimensions which are at most 25% of the dimensions of the lubricant passage openings in this direction.
- both the further ventilation opening and the lubricant passage opening are delimited both in the first direction and in the second direction by a respective continuous edge.
- the two directions are perpendicular to one another and each intersect the corresponding edge of the respective opening.
- the further vent opening has similar dimensions to the lubricant passage opening in the first direction, but is significantly smaller than this in the second direction.
- the dimensions of the further vent opening are correspondingly Voltage in the first direction at least 75%, at least 80%, at least 85% or at least 90% of the dimensions of the lubricant passage opening.
- the dimensions of the further vent opening are at most 125%, at most 120%, at most 115% or at most 110% of the dimensions of the lubricant passage opening.
- the dimensions of the first vent opening in the first direction particularly preferably correspond to the dimensions of the lubricant passage opening, likewise in the first direction.
- the dimensions of the further vent opening in the first direction are at most 50%, at most 25%, at most 20%, at most 15% or at most 10% of the dimensions of the lubricant passage opening, also in the second direction.
- Such a configuration of the further vent opening enables particularly effective venting without reducing the rigidity of the upper part of the lubricant tub in an impermissible manner.
- the further vent opening is particularly preferably round.
- a further development of the invention provides that the ventilation opening has dimensions in the first direction and the second direction which are at most 25% of the dimensions of the further ventilation opening in the respective direction.
- the vent opening is significantly smaller than the further vent opening.
- Both the vent opening and the further vent opening are preferably round.
- a diameter of the vent opening is at most 25% of a diameter of the further vent opening.
- the dimensions or the diameter are particularly preferably smaller than 25%, preferably they are at most 20%, at most 15% or at most 10%.
- a high rigidity of the top part of the lubricant is achieved with good ventilation at the same time.
- a further development of the invention provides that the vent opening has a diameter of at least 1 mm and / or of at most 6 mm.
- the lower limit of 1 mm is used to achieve adequate venting of the respective chamber through the vent opening.
- the upper limit of 6 mm is used to avoid adverse effects on the rigidity of the upper part of the lubricant pan.
- the diameter is at least 1 mm and at most 6 mm, at most 5 mm, at most 4 mm, at most 3 mm or at most 2 mm.
- the diameter can be at least 2 mm and at most 6 mm, at most 5 mm, at most 4 mm or at most 3 mm.
- the diameter is at least 3 mm and at most 6 mm, at most 5 mm or at most 4 mm and so on.

- FIG. 1 shows a schematic representation of part of an internal combustion engine 1, namely a region of a lubricant pan 2. Specifically shown is a lubricant pan upper part 3 of the lubricant pan 2, which has a lubricant sump, which is delimited jointly by a lubricant pan lower part and the lubricant telwanne upper part 3, from a lubricant sump in a cylinder crankcase the internal combustion engine 1 separates recorded crankcase.
- the upper part 3 of the lubricant pan has a basic component 4 which delimits the crank chamber in the direction of the lubricant pan 2 or in the direction of the lubricant sump.
- a basic component 4 which delimits the crank chamber in the direction of the lubricant pan 2 or in the direction of the lubricant sump.
- the webs 5 are arranged with respect to one another in such a way that they form chambers 6 which are closed at the edge in section between them. These are also only indicated as examples.
- lubricant passage openings 7 open, which are formed in walls 8, which form part of the top part of the lubricant wall 3 or of the basic component 4.
- the walls 8 delimit depressions which are open in the direction of the crankcase. It can be seen that the lubricant passage openings 7 are arranged in several rows, which run at least approximately or even exactly parallel to one another.
