Definitions
- the invention relates to a fluid introduction, which can be used in particular as exhaust gas recirculation in the intake tract of an internal combustion engine, according to the preamble of claims 1 and 7
- EP 486 338 A1 proposes to design the exhaust gas inlet as double-walled.
- the exhaust gas is introduced into the intake tract through the inner tube, the cavity resulting between the double wall being insulating against the contact point of the exhaust gas intake with the intake manifold
- part of the fresh air drawn in is passed through the intermediate space, which is removed in front of a throttle valve and reaches the intermediate space via a bypass line.
- the cooling air returns to the intake tract through corresponding openings parallel to the exhaust gas flow
- a thermally resilient gas guide element 26 (compare FIG. 2) can be provided, which protects the wall of the suction tract from a direct impact of the hot exhaust gas flow.
- the hot exhaust gas flow has sufficient time to mix with the intake air.
- such an additional component means an increased design effort and also increases the weight of the intake tract. Both are not desired in terms of the highest possible economy in the production and use of the intake tract
- the feasible exhaust gas recirculation rates are limited upwards high thermal load of the intake tract in the area of the exhaust gas recirculation system.
- a gas guide element in accordance with EP 886 063 A2 must be provided in the intake tract.
- the solution according to the invention for the introduction of fluid provides for the inlet connection in the end region which extends into the interior of the cavity structure to be provided with outflow means which point in the direction of the flow direction of the fluid which is passed through.
- This constructive measure makes the flow of the fluid to be introduced in the direction the flow in the cavity structure is redirected, thereby preventing the introduced fluid flow from directly hitting a wall of the cavity structure.
- the fluid to be introduced is captured by the flow of the fluid being passed through and is carried away by the suction jet pump effect, as a result of which rapid mixing takes place.
- the mixing simultaneously causes cooling of the fluid to be introduced and heating of the fluid to be passed through The resulting temperature is, however, in the range of the permissible thermal stress on the cavity wall
- the discharge openings are arranged along the flanks at the end region of the inlet connector.
- the large number of openings improves the mixing effect, since the fluid flow of the fluid to be introduced is broken up into many small substreams
- the discharge openings are provided with baffles.
- these baffles can be produced in a simple manner by punching Fluids with the conductive fluid
- the baffles cause the fluid flow to be introduced to emerge at the end region of the inlet connection, which prevents direct contact of the fluid to be introduced with the walls of the cavity structure. ra restructuring
- the inlet connection with a flow-optimized outer contour in relation to the flow passed through in the cavity structure.
- the inlet connection When flowing around the inlet connection, there is a laminar flow along the outer contour of the inlet connection, in particular the inlet connection End area This improves the mixing result with the fluid to be introduced
- a further embodiment of the invention provides that the end region of the inlet connector is formed by a pipe piece which is provided with openings on the sides around which the flow flows.
- the cross section of the pipe piece does not have to be circular. Rather, different cross-sectional shapes are conceivable
- Another possibility is the production from a tubular semi-finished product, which is deflected.
- the openings then have to be punched in, for example provided with a plug-in connection, and can be plugged onto the inlet connection with the aid of this.
- This component can also be retrofitted into intake systems that are already in use
- the pipe piece is open at the end. This accommodates a design of the pipe piece from a tubular semifinished product.
- the open pipe end serves as an additional inlet opening for the recirculated exhaust gas
- An alternative fluid inlet consists of three structural functional areas, the cavity structure, the inlet connector and the connection structure.
- the cavity structure is suitable for the passage of a fluid and can, for example, consist of an intake pipe for an internal combustion engine.
- the inlet connector is suitable for connection to a supply line, whereby the inlet pipe is used to connect the inlet pipe hot fluid is also provided, a connection structure is provided which serves on the one hand for fastening the Einieit 100 ⁇ s in the wall of the cavity structure and secondly enables a seal between these two components
- the fluid inlet described must be designed for the thermal loads caused by the introduction of the hot fluid.This means that the inlet connector must be temperature-resistant to the fluid to be introduced. However, lower-melting materials, e.g. plastic, are often used for the cavity structure because the inlet connector Heavily heated by the fluid to be introduced, the connection point between the latter and the cavity structure must be insulated to such an extent that the cavity structures in this area are not thermally stressed.
- the connection structure is provided for this purpose, whereby heat conduction from the inlet connection to the cavity structure takes place Starting from the inlet connection to the cavity structure, a temperature gradient is introduced in the connection structure, so that the contact area between connection structure and cavity structure is cooler than the inlet connection
- a further reduction in the temperature in the connection between the cavity structure and the connection structure is achieved according to the invention in that means are provided that reduce the heat from the inlet pipe into the connection structure from the outset. This naturally also lowers the thermal load on the connection point between the connection structure and the cavity structure.
- higher exhaust gas recirculation rates can be achieved than with a fluid introduction without the means for reducing the heat input.
- exhaust gas recirculation rates of up to 60% are sometimes required, which can only be introduced into an intake tract made of plastic if the means mentioned are used.
- the inlet connection piece can be made of ceramic as a means for reducing the heat input.
- This material has sufficient temperature resistance to the hot fluid to be introduced.
- metallic materials which are the usual construction material for the inlet connector, the thermal conductivity of ceramics is significantly lower.
- the inlet nozzle thus acts as a thermal insulator, so that a lower amount of heat is introduced into the connection structure.
- connection structure from ceramic. This also prevents excessive heat conduction in this area.
- the inlet connection and the connection structure can be produced in one piece, which advantageously reduces the manufacturing costs.
- a further advantageous design of the means for reducing the introduction of heat consists in a double-walled construction principle of the inlet connection. This has an inner wall and an outer wall, the fluid located in the space between these walls acting as an insulator. The fluid to be introduced is passed through the cross section formed by the inner wall.
- the space As an insulator to reduce the introduction of thermal energy into the connection structure, this is attached to the outer wall of the inlet connector.
- the insulation effect of the intermediate space can be increased if the embodiment of the invention described is combined with the suction jet pump effect already known from the prior art.
- the Fluid in the intermediate space is thus constantly exchanged, which prevents it from heating up. This keeps the outer wall cooler from the start, which also reduces the heat input into the connection structure.
- the temperature gradient in the connection structure can also be influenced. This is done by means of enlarging the surface of the connection structure. On the one hand, this increases the amount of heat radiation which is proportional to the surface of the connection structure, as a result of which the connection point between the connection structure and the cavity structure heats up less.
- the connection structure can be made of thin sheet metal, giving it a bellows-like structure. The corrugated walls of this bellows-like structure lead to sufficient stiffening and at the same time enlarge the surface.
- Another possibility is a bowl-like design of the connection structure, the outer radius of this bowl being chosen larger than would be necessary for the installation of the inlet connection.
- the bowl can also be made from thin sheet metal and stiffened with beads. The beads also lead to a further increase in the surface.
- connection structure is manufactured as a bayonet lock in accordance with an expedient embodiment of the inventive concept.
- This creates a module that can be easily integrated into cavity structures. Especially if these are made of plastic, the corresponding receptacle can be easily integrated into the wall structure as a counterpart of the bayonet catch.
- the inlet connector and connection structure can then be designed as a standard component, which means that large quantities can be achieved. This leads to an increased economy of the solution.
- the fluid inlet can be easily installed by means of the bayonet lock, the reduced assembly effort also contributing to a further increase in the economy of the fluid inlet.
- the described embodiments are suitable for reducing the thermal load on the connection between the inlet connector and the cavity structure, so that in relation to the fluid passed through there is a higher amount of hot material to be introduced Fluid can be added.

This cavity structure has an installation opening 11 through which an inlet connector 12 can be pushed into an interior 13 of the cavity structure Inlet 14 and to be understood as outlet 15, so that combustion air can flow through the cavity structure in accordance with the solid arrows indicated
- the inlet connection 12 consists of a connection 16 for an exhaust gas return line, which is also formed by an outer tube 17, a double-walled tube structure.
- An associated inner tube 18 is provided for conducting the exhaust gas, represented by a dashed arrow Einleitstutzens 12, and has discharge openings 20 for introducing the exhaust gas into the air flow of the cavity structure.
- the introduction of the exhaust gas is also indicated by dashed arrows
- Part of the cavity structure is also understood in this context to be a cover 22 which is fixed with screws 23 and sealed with the aid of an O-ring 24.
- An outer edge 25 of the bellows is provided with a tefflo ⁇ ng 26, which in turn is injected into the cover 22 has compared to the lid a higher temperature resistance, so that a certain introduction of heat through the bellows does not damage the entire device.
- An inner edge 27 of the bellows 21 is connected directly to the outer tube 17, for example by soldering
- the former has beads 28, which are connected to the outer walls of the inner tube 18.
- An annular space 29 formed by the inner tube and outer tube is used in addition to its insulating effect for the passage of intake air, which is used by a suction jet pump effect at the inner tube end 30 sucked through the annular space 29, into which it previously entered through inlet bores 31.
- intake air can additionally cool the inside of the bellows. The path of the cooling air flow is indicated by dotted arrows
- the structure of the end region 19 can be seen in FIG. 2 This forms an elongated cavity which is flowed around by the flow in the cavity structure 10 (solid arrows).
- the cavity 45 has the outlet openings 20 to the interior 13 as a connection through which the exhaust gas flow ( dashed arrows) can be introduced in the direction of the flow of the intake air.
- the exhaust gas stream first peaks on flanks 32 of the end region 19, in order to then gradually mix with the flow of the intake air.
- the end region is made of sheet metal.
- the openings can be opened easily Manufacture way by notching the material and bending it inward. This results in baffles 33 which facilitate an undisturbed escape of the exhaust gas through the opening 20
- a two-part inlet port 12 is shown.
- the first part is the E ⁇ d Siemens 19, which is designed according to Figure 1
- This is directly connected to a ceramic component that combines the functions of the connector 16 and a connecting plate 34 for mounting in the cavity structure 10
- the Ceramic material of this component acts as an insulator, so that the heat from the exhaust gas introduced (dashed arrow) is only passed on to the cavity structure 10 to a small extent
- the inlet connector 12 is cast directly into the installation opening 11 of the cavity structure 10 via the ceramic plate. This results in an easy-to-manufacture structural unit.
- the geometry of the inlet connector is very simple due to the two-part construction Injection molding process of the cavity structure to be injected directly The effort of a final assembly is therefore completely eliminated
- the inlet connection 12 according to FIG. 4 has a double-walled structure consisting of inner pipe 18 and outer pipe 17, but this is not flowed through by a cooling air flow (see dotted arrow in FIG. 1).
- the gas in the annular space 29 is thus not constantly replaced and still acts as an insulator between the outer and inner tube
- a sheet metal bell 35 is fastened to the outer tube 17 and serves to fasten the inlet connector 12 to the cavity structure 10.
- the sealing is carried out via an O-ring 24a between the sheet metal bell 35 and the installation opening 11.
- the sheet metal bell 35 is provided with beads 28a for reinforcement
- the outlet openings 20 are arranged obliquely. This measure serves to correct the direction of the exiting exhaust gas flow in the direction of the flowing intake air in the cavity structure.
- the exhaust gas flow is in fact twisted due to the deflection in the end region 19 in order to allow the exhaust gas flow to touch the cavity walls to avoid as long as possible after exiting the end region, the swirl pulse is eliminated with the aid of the obliquely arranged baffle plates in the openings 20. This process is indicated by the dashed arrows
- connection between sheet metal bell 35 and cavity structure 10 is made by a bayonet lock 36 whose mode of operation can best be understood with the aid of FIGS. 4 and 5.
- receiving ribs 37 are arranged on the cavity structure 10 Rotation of the inlet connector 12, a tab 39 arranged radially on the outer circumference of the sheet metal bell 35 slips, causing the sheet metal bell 35 is pressed onto the O-ring 24a.
- the receiving ribs 37 are attached to a mounting flange 40 which adjoins the installation opening 11 and is stabilized by support ribs 41 towards the cavity structure.
- the flow-optimized shape of the end region becomes clear.
