Definitions
- Piston for an internal combustion engine and combination of a piston with a ⁇ lleinspritzanordnunq
- the invention relates to a piston for an internal combustion engine according to the preamble of claim 1 and a combination of such a piston with an oil injection arrangement.
- the invention is based on a prior art in the form of a piston with a cooling channel, which as
- Known cooling channels may have different cross-sectional shapes and particular configurations, such as e.g. have a wave-shaped course.
- a piston which has no combustion bowl.
- the piston is formed with two or more separate cooling channels, which are filled by an inclined nozzle, wherein holes for an oil supply in the cooling channels are arranged obliquely according to the jet direction.
- a piston which has two separate cooling channels, wherein two inclined nozzles are provided for an oil supply and holes for an oil supply in the cooling channels are arranged obliquely according to the jet direction.
- the invention has for its object to provide with simple means improved in terms of cooling effect piston and a populated arrangement with a cooling channel.
- the piston according to the invention has a cooling channel which has at least two sections which are at different levels with regard to the height along the piston axis and / or in the radial direction.
- a second Measure which can be combined with said first measure, but also, as the first measure may be provided alone, the piston according to the invention two or more cooling channels, of which at least two in terms of the height along the piston axis and / or are located in the radial direction at different levels.
- the basic idea of the invention is to provide a plurality of cooling channels or interconnected cooling channel sections, which extend in different zones of the piston and thus bring about efficient cooling. In particular, this can be used to lower the temperatures in the entire piston without the hitherto chosen, complex measures being required.
- the arrangement "at different levels” it is to be understood that a superposition and / or side-by-side arrangement of self-contained cooling channels or
- Cooling duct sections is meant.
- the teaching described herein differs from known cooling channels, which may have a wave-like course, and in which, accordingly, individual, comparatively short sections are at different levels.
- this difference exists with respect to cooling channels, which may have an annular section and one of which branches off, inclined section.
- Such sections are not at different levels insofar as they are directly connected.
- no separate sections are provided in such a way that they can be seen as a separate openings in a sectional view containing the axis. Rather, one recognizes in the mentioned
- the invention provides that, for example, cooling ducts or cooling duct sections that are along the piston axis at different (axial) level, are delimited from each other in the region of the shortest connection between two such channels or sections by piston material.
- they could be fluidly connected by a suitable, in the broadest sense helical connection.
- the connection between two such cooling duct sections can also be effected by connecting openings or bores extending substantially parallel to the piston axis. This is especially true when the two cooling duct sections are only in the direction of the piston axis, but not in the radial direction at different levels.
- Two cooling channels or cooling channel sections extending in the radial direction, i. Starting from the piston axis to the piston skirt out, at different levels, so radially further outward or further inside, can also be connected by a largely helical connection or a largely straight connection opening or bore. Since the cooling duct sections are at radially different levels, such a connecting opening or bore would be inclined in a suitable manner with respect to the piston axis. If a cooling channel has at least two sections which, as described, are at different levels, the filling can be carried out such that the oil is brought into the upper channel, for example by means of a nozzle, and from there flows into the lower channel and finally exits ,
- the measures according to the invention make it possible to produce an optimized cooling effect by means of a suitable, still comparatively simple design of one or more cooling channels.
- the cooling channels or cooling channel sections can be laid in the zones which are particularly exposed to temperature. There, a favorable temperature reduction of the piston can be ensured by the cooling channels.
- the piston must be changed by the formation of multiple cooling channels or cooling channel sections in such a small extent that can be used existing casting devices in an advantageous manner. For example, those special casting devices that are required for the introduction of reinforcing fibers can also be used. This also results in a particularly good economy of the piston according to the invention.
- At least one inflow and / or outflow runs essentially parallel to the piston axis.
- all inflows and / or outflows are formed parallel to the piston axis.
- Such inflows and / or outflows can be produced by casting cores or similar methods by means of conventional casting technology. This allows a cost-effective production. However, it is also conceivable to produce inflows and / or outflows subsequently by drilling or similar production measures.
- the piston is preferably made of aluminum or an aluminum alloy, and is preferably installed in a diesel engine, preferably a direct-injection engine. Reinforcements, for example by remelting, alloying, introduction of metallic or ceramic fibers, or of dispersion materials can also be incorporated in the pistons.
- individual cooling channels can be connected to each other in terms of inflow and / or outflow, it has proven to be advantageous if the individual cooling channels have fluidically separate inflows and / or outflows.
- this offers the advantage that, as explained in more detail below, either the oil pressure for the respective cooling channel can be adjusted separately, or by a schxägêt nozzle, the filling can be done by a single nozzle, and at the same time each cooling channel can be separated and reliably supplied with coolant.
- the fluidic separation offers the advantage that the coolant can flow away unhindered and does not hinder the subsequent flow of colder coolant.
- At least one cooling channel in a region axially below the combustion chamber trough.
- This cooling channel can be arranged, for example, in the region below an outer edge of the combustion bowl.
- the piston of the invention unfolds in terms of the improved cooling effect already as such its advantages.
- the oil injection arrangement has at least two nozzles. In this way, the respective nozzle for the injection of coolant, in particular oil can be adjusted in the respective cooling channel.
- the nozzle which is provided for the injection of coolant into a cooling channel in the region of the piston head a higher oil pressure than other nozzles.
- the amount of coolant, in particular of the oil can be reduced in an advantageous manner.
- a preferred embodiment is that the one nozzle provided has two or more outlet channels.
- a simple structure can be realized by a single nozzle is arranged obliquely so that the coolant jet is inclined, so that this, depending on the position of the piston, enters one or more different cooling channels. Due to the oblique formation of a coolant jet, the coolant can thus, for example, in different positions of the piston between the top and bottom dead center, i. in the direction of the piston axis, to enter different inlet openings, which are located in the radial and / or circumferential direction at different locations. In other words, different cooling channels can be filled in different positions of the piston.
- the coolant jet enters into a cooling channel only in one position, for example at bottom dead center, and in another position, for example at top dead center, the coolant jet strikes the piston crown and cools it.
- a second cooling channel can be filled by its own nozzle.
- FIG. 1 shows a sectional view of the piston according to the invention with an oil injection arrangement.
- Fig. 2 is a representation of the internal configuration of the piston according to the invention.
- FIG. 3 shows the combination shown in FIG. 1 viewed from an underside

- the piston 10 according to the invention which may be made of aluminum or an aluminum alloy, in particular cast, generally a combustion bowl 12, which may be ⁇ -shaped, a plurality of annular grooves 14 and two (it is only one to recognize) piston pin bosses 16.
- the illustrated embodiment of the piston according to the invention has two cooling channels 18, 20 along the piston axis (not shown), which extends in the vertical direction according to FIG.
- the cooling channels can, as can be seen in Fig. 1, have a substantially circular cross-section.
- a first cooling channel 18 is located in a region "next to" the combustion chamber trough and in the axial direction to comparatively high level, in particular a short distance below the piston crown 22. In that regard, it is referred to below as the bottom cooling channel 18.
- a second cooling channel 20 is provided at a level below the combustion chamber trough 12 and the bottom cooling channel 18.
- This cooling channel is referred to below as a hollow cooling channel 20. It is not only, as mentioned, with respect to the height in the direction of the piston axis at a lower level, but is also formed at a radially inner position. At this point, this well cooling channel 20 can provide particularly efficient for the cooling of the hot zones between the combustion bowl 12 and the piston pin 16.
- the cooling channels 18, 20 are formed with inflows 32, 36 for a supply of coolant.
- the inflows 32, 36 are substantially parallel to the axis of the piston 10th
- the two nozzles are arranged on opposite sides of the piston pin (not shown), the is mounted in the piston pin eye 16. They are thus arranged on the pressure and the counterpressure side, although for other applications it is presently preferred to arrange both nozzles on the counterpressure side.
- both nozzles produce an approximately vertically upwardly directed coolant jet 28 or 30, which enters the respective inflow 32, 36 of the cooling channel 18 and 20, respectively.
- one drain opening is provided at an approximately opposite point, as shown and explained in more detail below.
- the inner life of the piston 10 shown in FIG. 1 can be seen in addition.
- the two cooling channels 18 and 20 are annular and provided at a constant level.
- the cross section does not change. However, it could also be changeable, in particular wave-shaped.
- the trough cooling channel 20 is provided not only at a lower level, but radially within the bottom cooling channel 18. As a result, the space required for the inflow 32 of the floor cooling channel 18 is made available.
- both the inflows 32, 3 ⁇ and the outflows 34, 38 are aligned substantially parallel to the piston axis.
- both drain openings are shown in addition to the details shown above.
- the opening for the drain 34 for the radially inner trough cooling channel is in the embodiment shown opposite the inflow 36. This also applies to the drain 38 for the bottom cooling channel 18, which is located opposite to its inflow 32.
- Fig. 4 shows a sectional view of a second embodiment of the piston 10 according to the invention, in which two cooling channel sections 40, 42 are provided, which are in terms of height along the piston axis at different levels. In contrast, they are in the embodiment shown in the radial direction at the same level.
- This connection consists essentially of a connecting channel extending approximately parallel to the piston axis, which could also be referred to as a bore.
- a nozzle 24 is provided, which brings a coolant jet 30 in the region of the upper cooling channel section 42.
- connection 52 is provided between them.
