Definitions
- the present invention relates to an arrangement for introducing recirculated exhaust gas into a fresh air system of an internal combustion engine.
- the invention also relates to an internal combustion engine whose fresh air system is equipped with such an arrangement.
- an external exhaust gas recirculation is also used, in which exhaust gas is taken from an exhaust system of the internal combustion engine and fed to a fresh air system of the internal combustion engine.
- the exhaust system leads in a conventional manner, the resulting in the combustion in the combustion chambers of the internal combustion engine exhaust gases from the internal combustion engine.
- the fresh air system supplies fresh air to these combustion chambers for new combustion processes. Upstream of these combustion chambers recirculated exhaust gas is now introduced into the fresh air system. In the area of such a discharge point, an arrangement of the type mentioned is used.
- An arrangement for introducing recirculated exhaust gas into a fresh air system of an internal combustion engine is known from EP 2 218 897 A1, in which an inlet connection has a connection flange which is arranged via a seal on an inner side of a mounting member, wherein the mounting member on the outside of a channel Fresh air system is arranged such that it closes a connection opening of the channel through which the inlet nozzle with the nozzle flange and the seal protrudes into the channel.
- a coolant channel is arranged on an outer side of the mounting member.
- the present invention is concerned with the problem of providing for an arrangement of the type mentioned in an improved or at least another embodiment, in particular by a simple and low cost design and in particular has sufficient thermal decoupling between the exhaust gas recirculation system and the fresh air system.
- the invention is based on the general idea to set the inlet nozzle with a nozzle flange outside of a plastic component of the fresh air system and to fix it with the help of screws, the screws are passed through plastic bushes.
- the nozzle flange can preferably be supported on the plastic component via the plastic bushes. This makes it possible in particular to avoid direct contact between the inlet nozzle and the plastic component. As a result, thermal stresses between the preferably metallic inlet nozzle or the preferably metallic nozzle flange on the one hand and the plastic component on the other hand can be reduced.
- the invention proposes to use the preferably metallic inlet nozzle in a connection opening, which is formed in the plastic component of the fresh air system.
- the inlet nozzle may be inserted into the connection opening in such a way that it protrudes into the interior of the plastic component, so that the recirculated exhaust gas can be supplied to the fresh air flow at a distance from the plastic component.
- the inlet nozzle is expediently cylindrical.
- the inlet connection can furthermore be axially open so that the recirculated exhaust gas can enter the fresh air flow axially with respect to the inlet connection.
- the inlet connection may optionally have at least one radial opening within the plastic component, so that the recirculated exhaust gas is referred to lent of the inlet can also flow radially into the fresh air flow.
- the inlet connection piece has the connection flange, which according to a preferred embodiment can be integrally formed on the inlet connection piece and accordingly formed with the same material.
- a preferably metallic exhaust gas recirculation line is flanged to a side facing away from the plastic component side.
- the nozzle flange serves on the one hand to connect the exhaust gas recirculation line to the inlet connection.
- the plastic component of the fresh air system has a flange portion which encloses the connection opening in the circumferential direction.
- the nozzle flange is now arranged on the outside of this flange region, so that the nozzle flange thus on the other hand also serves to fasten the inlet nozzle to the plastic component.
- the nozzle flange has a plurality of bushing openings, in each of which a plastic bushing is inserted.
- the nozzle flange is now screwed by means of several, preferably metallic, screws with the flange, said screws are each passed through one of the plastic sockets.
- the nozzle flange can be arranged at a distance from the flange region.
- efficient thermal decoupling results, since heat transmission through heat conduction is precluded and only heat transfer by thermal radiation is possible, which is significantly lower.
- the inlet nozzle has an outer cross section which is smaller than an opening cross section or inner cross section of the connection opening, so that the inlet connection is radially spaced from an opening edge with respect to the nozzle longitudinal direction.
- the inlet nozzle has no direct contact with the plastic component.
- a seal surrounding the connection opening can be arranged between the connection flange and the flange region.
- This seal prevents leaks and false flows and in particular leakage of the recirculated exhaust gas into the environment.
- the seal can be used according to an advantageous development as a spacer, if it is equipped with appropriate stability, so that it can be used for spacing the neck flange of the flange.
- the respective plastic bushing may have a bushing flange with which the respective plastic bushing is supported on the neck flange on a side facing away from the flange region.
- the associated screw is supported with a screw head on said bushing flange either indirectly via a disk or directly.
- the respective plastic bushing can be inserted into the associated bushing opening and latched to the neck flange on a side of the neck flange facing the flange region.
- the plastic bushing may have correspondingly radially resilient latching elements which yield radially inwardly upon insertion of the respective plastic bushing into the associated bushing opening and emerge again from the respective bushing opening when the plastic bushing is completely inserted on the opposite side, thereby springing back radially outwards Behind the neck flange on this side.
- the socket opening with a Self-tapping internal thread to be cut when screwing the plastic bushing into the outside of the plastic bushing.
- the respective plastic bush can also be fixed via a press fit in the bushing opening on the neck flange.
- the respective plastic bushing is supported axially on the end face on the flange area.
- the plastic bushing protrudes axially over the nozzle flange with respect to the longitudinal direction of the inlet nozzle, so that an axial spacing between the nozzle flange and the flange region is already achieved via the plastic bushing.
- At least one spacer element can be arranged between the nozzle flange and the flange region, which encloses, for example, one of the plastic bushes in an annular manner. In this way, the desired axial distance between the nozzle flange and flange area can be realized particularly easily.
- the plastic bushings can be made of a duroplastic.
- Thermosets can be realized with a relatively high thermal resistance.
- the plastic component of the fresh air system can have a collar which projects into the connection opening and protrudes outward, from which a component flange forming the flange region emerges.
- said collar and associated component flange can be formed integrally, that is, of the same material, on the plastic component.
- the component flange can be arranged free-standing with respect to the remaining plastic component.
- an air gap insulation is achieved between the plastic component and the component flange, which additionally improves the thermal decoupling.
- a desired axial distance between the component flange and the plastic component can be realized in a particularly simple manner in that the collar protrudes in the axial direction outwardly from the plastic component so that the desired axial distance is established.
- the screws can be designed to be self-tapping or self-tapping, so that they can penetrate into the plastic of the flange area when screwed in without corresponding screw openings on the flange area having to be formed beforehand for this purpose. This simplifies the assembly.
- the flange region can have a greater wall thickness in screw regions, which in each case lie opposite one of the plastic bushings, than in regions adjacent thereto. This ensures that the screws are comparatively deep in the material of the Flange area can be screwed, which improves the anchoring of the screws on or in the flange area.
