Definitions

  • the invention relates to a distribution device for distributing fluid flows and a method for operating a motor vehicle with an internal combustion engine.
  • Piston cooling is used in modern internal combustion engines. Such piston cooling can be realized, for example, by using a fluid to cool the piston.
  • the fluid can be, for example, a lubricating oil.
  • the fluid can be applied to the pistons using so-called piston cooling nozzles.
  • piston cooling nozzles can be switched off, for example in order to deactivate the piston cooling in certain operating states in which no piston cooling is required. This can be done, for example, by means of pressure-controlled valves integrated into the piston cooling nozzles. If the valves are subjected to a pressure that exceeds a certain limit pressure, the valves open.
  • distribution devices for distributing fluid streams are known from the prior art, in which a fluid stream entering a main channel is distributed to a plurality of outlet channels branched off from the main channel.
  • a distribution device is known in which the fluid flows entering the outlet channels from the main channel can be shut off by means of a shut-off device. The shut-off takes place in such a way that the outlet channels branched off from the main channel are shut off at the same time by moving a shut-off element of the shut-off device.
  • shut-off device which makes it possible to enable different flow rates by selectively shutting off or releasing two outlet channels branched off from a main channel, which unite again after branching off from the main channel.
  • the DE 10 2012 212 597 A1 discloses an internal combustion engine in which oil spray devices branch off from a main oil channel.
  • the oil spray devices are designed to direct the oil either to a first nozzle or to a second nozzle depending on the pressure in the main oil channel.
  • the spray devices cannot be controlled independently of the oil pressure in the main oil channel, and the construction is complex since a plurality of oil spray devices are required to switch back and forth between the first and second nozzles of a plurality of cylinders.
  • the EP 1 995 472 A1 discloses a hydraulic distributor in which distribution devices are designed to connect a hydraulic oil flow to different outputs of the distributor. However, this requires comparatively complex mechanics with complicated oil distribution devices.
  • the DE 10 2013 201 390 A1 discloses an internal combustion engine with oil spray devices, in which the oil supply to the oil spray devices of deactivated cylinders can be selectively deactivated.
  • the CN 106 812 564 A also discloses selectively deactivatable oil spray devices that can be deactivated by means of a shut-off device arranged in a channel.
  • the invention is therefore based on the object of demonstrating a distribution device for distributing fluid flows and a method for operating an internal combustion engine in which the problems described above do not occur or at least occur to a reduced extent.
  • the object is achieved by a distribution device for distributing fluid flows and a method for operating an internal combustion engine according to the independent claims.
  • the dependent claims relate to advantageous embodiments.
  • the distribution device for distributing fluid flows has a main channel and a plurality of outlet channels branched off from the main channel.
  • the distribution device is designed to distribute a fluid flow entering the main channel to the outlet channels.
  • the fluid can in particular be a lubricant and/or a coolant, for example a lubricating oil, which fulfills a cooling function in addition to its lubricating function.
  • an inner channel is arranged within the main channel.
  • the inner channel is designed to direct fluid penetrating into the inner channel to at least one of the outlet channels.
  • the shut-off device has a shut-off element for shutting off a fluid flow entering the inner channel from the main channel.
  • This arrangement makes it possible to specifically shut off the fluid flow to the at least one outlet channel to which the fluid penetrating into the inner channel is directed.
  • Other outlet channels branched off from the main channel are not affected by the shutting off of the fluid flow, i.e. the fluid flow entering the main channel continues to be distributed to these outlet channels. Only those outlet channels that are supplied with fluid through the inner channel are blocked by the shut-off device.
  • the outlet channels to which the fluid penetrating into the inner channel is directed can only be reached via the inner channel by the fluid penetrating into the main channel.
  • the distribution device can be designed in such a way that the fluid flow entering the inner channel from the main channel initially washes around the inner channel as it passes through the main channel.
  • Such an embodiment, in which the inner channel is positioned within the fluid flow in the main channel offers the particular advantage that existing constructive concepts can be supplemented by the inner channel and the targeted shut-off of at least one outlet channel branched off from the main channel.
  • the flushing around the inner channel makes it possible for the outlet channels branched off from the main channel, which are not supplied with fluid via the inner channel, to continue to be reached by the fluid flow.
  • the method according to the invention for operating an internal combustion engine provides that a fluid flow directed to a piston to be cooled is interrupted by means of a shut-off element if the cylinder to which this piston belongs is not fired due to a cylinder deactivation, while at least the piston is one Another cylinder, which is fired, is further cooled by means of a fluid flow branched off from the interrupted fluid flow.
  • switching off the piston cooling of at least one cylinder can be achieved in particular by means of the distribution device described. This can be easily integrated, in particular, into existing design concepts, so that the method for operating an internal combustion engine can be carried out in an advantageous manner. In principle, however, it is also possible to enable a selective shutdown of the piston cooling of individual cylinders depending on their cylinder shutdown using other technical devices.
  • the distribution device described for selectively shutting off fluid flows other than those used for piston cooling is in particular part of a motor vehicle.
  • the fluid streams directed to the individual outlet channels can be used, for example, to supply gears with a fluid.
  • the shut-off function can be used in particular to supply these transmissions with the fluid depending on certain driving conditions. This is particularly advantageous if it is a hybrid vehicle or a vehicle with a hybrid drive. In such vehicles, parts of the drive train, in particular transmissions, are temporarily not used, especially if the motor vehicle is temporarily operated purely electrically or with a purely internal combustion engine. In these cases it is possible with the distribution device, depending on the corresponding one Operating state to cool parts of the drive train, in particular individual transmissions, selectively depending on the operating state.
  • the inner channel is formed by a tube.
  • the inner channel can in particular be pressed into the main channel.
  • the pipe that forms the inner channel can have branches that end at the branched outlet channels, which are to be supplied with the fluid through the inner channel, when the inner channel is in its intended position in the main channel.
  • the inner channel can have spacer elements. These can be separate components; alternatively and/or additionally, the spacer elements can be molded onto the component that forms the inner channel, for example a tube. The spacer elements make it possible to press a pipe into the main channel whose outside diameter is smaller than the diameter of the main channel. This makes it possible for the fluid in the main channel to flow around the inner channel.
  • the main channel can be formed by a cast component. Casting processes enable the cost-effective production of components with comparatively complicated geometries.
  • the channels can have already been created during casting; alternatively and/or additionally, it is possible for the channels to be subsequently introduced into the component, for example in the form of bores.
  • the advantage of the distribution device described is that, in contrast to comparable switchable distribution devices according to the prior art, in which the shut-off device is guided in the main channel, there are no high demands on the processing of the material surfaces that delimit the main channel.
  • the inner channel is designed as a pressed-in tube, it is possible to press it, for example, into an unprocessed or almost unprocessed casting.
  • the shut-off device can be plugged into the main channel. By plugging it into the main channel, the shut-off device can be easily installed. It is possible for the shut-off device to be attached to the component that forms the inner channel. This results in a very simple installation overall.
  • the distribution device can be assembled in a simple manner by first pressing the pipe into the main channel and then inserting the shut-off device into the main channel at the same time and is attached to the pipe.
  • the shut-off element can have a housing which is arranged within the main channel and is initially flowed through by the fluid flow entering the inner channel from the main channel before the fluid flow enters the inner channel.
  • the fluid flow flows from the main channel through the housing of the shut-off device into the inner channel.
  • the shut-off element can have a shut-off element for shutting off the fluid flow entering the inner channel from the main channel, which moves parallel to the main direction of extension of the main channel to shut off the fluid flow.
  • a shut-off element for shutting off the fluid flow entering the inner channel from the main channel, which moves parallel to the main direction of extension of the main channel to shut off the fluid flow.
  • the shut-off element can be designed in such a way that the shut-off element is subjected to forces acting in opposite directions in both directions of movement of the shut-off element due to the pressure of the fluid. In this way, it is particularly possible for the shut-off device to be designed to be pressure-balanced. In other words, this means that the actuation forces are in particular independent of the pressure of the fluid and the position of the shut-off element along its direction of movement.
  • the shut-off device is a solenoid valve.
  • a solenoid valve offers the advantage of being able to be controlled in a simple and direct manner by a control device due to its direct electrical actuation. In this way it is possible, for example, for a control device that causes a cylinder to be switched off to simultaneously switch off the piston of the switched off cylinder or the pistons of the switched off cylinders.
  • solenoid valves also offer the advantage that the actuation state of the valve is independent of the pressure of the fluid. This makes it possible, for example, to realize load states of an internal combustion engine that are associated with higher oil pressures without the shut-off device being automatically actuated.
  • the distribution device 10 shown as an example in the figures has a main channel 12. As shown, this can have a circular cross section and extend along a main extension direction X.
  • the distribution device 10 also has a plurality of outlet channels branched off from the main channel 12. In the example shown, these are the outlet channels 14, 16, 18, 20, 22 and 24.
  • the distribution device 10 can be, for example, an oil gallery of a cylinder crankcase.
  • the outlet channels 14, 16, 18, 20, 22, 24 shown in the example shown can in particular be assigned to different elements of an internal combustion engine to be lubricated and/or cooled and supply them with the fluid, which can be an oil, for example .
  • the outlet channel 14 can supply the cylinder head
  • the outlet channel 18 can supply a bearing
  • the individual outlet channels 16, 20, 22 and 24 are assigned to individual piston cooling nozzles for cooling the pistons of the cylinders of the engine.
  • each of the outlet channels 16, 20, 22 and 24 can be assigned to a piston of a cylinder of a four-cylinder engine.
  • an inner channel 26 is arranged within the main channel 12.
  • This inner channel 26 is designed to direct fluid penetrating into the inner channel 26 to at least one of the outlet channels, for example to the outlet channels 20 and 22 as shown.
  • the distribution device 10 also has a shut-off element 28 for shutting off a fluid flow entering the inner channel 26 from the main channel 12.
  • the distribution device 10 can be designed, as in the example shown, in such a way that the fluid flow entering the inner channel 26 from the main channel 12 initially washes around the inner channel 26 when passing through the main channel 12.
  • this can be made possible by the fact that the inner channel 26 is formed by a tube whose outer dimensions, or its outer diameter, is smaller than the dimensions of the main channel 12, in particular than its diameter.
  • the one from the wall of the Main channel 12 spaced arrangement of the inner channel 26 can be made possible, as in the example shown, by using suitable spacer elements 30 to fasten the inner channel 26 in the main channel 12.
  • the embodiment shown in the figures shows an inner channel 26, which can be pressed into the main channel 12 in a simple manner.
  • the inner channel 26 can have branches 31.
  • the inner channel 26 can be positioned in the main channel 12 in such a way that the branches 31 are positioned at locations where the outlet channels that are to be shut off by the shut-off device 28 branch off from the main channel 12. In the example shown, these are the exit channels 20 and 22.
  • the shut-off device 28 can be inserted into the main channel 12.
  • the shut-off element 28 can be arranged at least partially within the main channel 12, as in the example shown. This makes it possible for the fluid which penetrates from the main channel 12 into the inner channel 26 to first penetrate into a housing 32 of the shut-off element 28.
  • the housing 32 can have openings 34 which allow the fluid to penetrate into the housing 32.
  • the shut-off element 28 can have a shut-off element 36, shown as an example. As shown in the figures, the shut-off element 36 can move along the direction This process is in the Figures 2 and 3 shown. In Figure 2 the fluid can flow through the openings 34 into the inner channel 26. In Figure 3 the flow path is interrupted by the shut-off element 36.
  • shut-off device 28 can be plugged onto the inner channel 26 as shown in the example.
  • shut-off element 28 and/or inner channel 26 can have suitable end regions 38, 40. These can, for example, have insertion bevels as shown in order to make it easier to plug together the shut-off element 28 and the inner channel 26.
