Definitions
- Intake system especially for use as an intake duct
- the invention relates to an intake system, in particular for use as an intake duct of an internal combustion engine, according to the preamble of patent claim 1.
- Intake systems for internal combustion engines are provided with shunt resonators, in particular in the area of the intake manifold, in order to dampen the intake noise.
- these shunt resonators consist of a resonator chamber and a resonator neck which connects the resonator chamber to the intake manifold.
- This basic form of the shunt resonator can be varied depending on the particular application. Several necks are conceivable which, with different lengths, allow damping of intake noises of different frequencies.
- the resonator space can have almost any shape.
- a disadvantage of the use of shunt resonators is their space requirement in the area of the intake manifold. This must be provided in the engine compartment, which is complicated by the limited space in the engine compartment.
- One approach to solving the problem is e.g. B. DE 3842248 A1.
- a resonator is proposed which is integrated in the housing of the intake system. This makes it possible to use the dead volume in the housing as a resonator space. There is therefore no need to provide additional installation space in the engine compartment.
- the resonator space described above must already be constructed at the
- Suction pipe can be used if the results regarding the
- the object of the invention is to provide a Helmholz resonator which takes up little space for itself and can also be retrofitted into an already existing intake manifold construction. Either special frequencies of the intake noise should be attenuated or broadband attenuation should be achieved.
- an inner structure is placed in the interior of the intake manifold and fastened there.
- This inner structure forms, together with the walls of the intake manifold, a resonator space which must have at least one opening to the intake manifold volume.
- Such an internal structure does not require any additional installation space in the engine compartment.
- the possibility of retrofitting is also advantageous. Above all, this is easy to achieve with intake manifolds that are manufactured using multi-shell technology.
- such an internal structure can also be introduced through the inlet or outlet openings of the suction pipe.
- the shape of the suction tube does not have to be changed, or only slightly.
- the inner structure z. B. glued in this only has to be adapted to a specific contour area of the intake manifold.
- the inner structure can be designed in such a way that, after installation in the intake manifold, it generates several resonator spaces of different volumes. With this measure, different frequencies in the intake area can be damped with emphasis.
- a sensible variant of the invention provides for the assembly of the inner structure in the interior of the intake manifold. This is arranged in front of the intake ducts to the cylinders. The noise damping therefore acts on all intake ducts of the intake manifold.
- the inner structure After a reasonable design of the inner structure, this is made of a flat component, eg. B. a perforated plate, and spacers constructed. The resonator chamber is thus created between the perforated plate and the intake manifold wall. It is advantageous that the inner structure can be produced from simple semi-finished products. This leads to an increase in economy in small series, e.g. B. in the tuning area.
- An alternative variant of the internal structure provides for its design as an insert. This can be made in one piece with a positive effect on the economy of the large series.
- the inner structure can have regions of different wall thickness. If several openings are provided in an internal structure, this results in different neck lengths for the shunt resonator.
- the positive effect of this measure is broadband attenuation of the intake noise.
- the inner structure and the suction pipe are made of the same material, the inner structure can also be welded into the suction pipe.
- a plastic insert can be joined in particular by the ultrasonic welding process. However, there are also other welding processes, e.g. B. the friction welding process possible.
- FIG. 1 shows a section through an intake manifold for an internal combustion engine with a row arrangement of the cylinders with the typical spiral shape of the intake port along the line A-A in FIG. 2,
- FIG. 2 shows the section B-B according to FIG. 1 through the collecting space of the suction pipe with a view of an insertion structure acting as a shunt resonator and the openings of the suction channels,
- Figure 3 is a schematic section through the wall of an inner structure with variable wall thickness and holes that serve as necks of different lengths for the resonator and
- FIG. 4 shows the schematic section through an insert structure for producing two resonator spaces of different volumes.
- a suction pipe 10 is shown in section through one of the intake channels 11.
- the combustion air is supplied to a plenum 12 through an inlet, not shown.
- the collecting space distributes the combustion air to the intake ducts 11, which are connected by outlets 13 to air inlets on the cylinder, not shown. Through this the combustion air is fed to the engine.
- Dead spaces 14 arising in the intake manifold can be used to dampen the intake noise.
- the suction pipe consists of several shells 15. Before the shells are welded to one another, inner structures 16 can be connected to inner walls 17 of the suction pipe.
- the inner structures have bores 18 which serve as necks for the resonator spaces formed by the inner structures.
- the inner structures can preferably be attached in the collecting space 12 of the suction pipe.
- the inner structures 16 can consist of a perforated plate 19 and spacers 20, which are attached between the inner wall 17 and the plate 19.
- the inner structure can consist of a single insert 21, which is preferably welded to the inner wall 17.
- welding shoulders 22 must be provided on the inner wall.
- the shells 15 are welded after the inner structures 16 have been introduced.
- the collecting space 12 is shown in longitudinal section. It represents the connection of an inlet 24 for the combustion air and the suction channel openings 25.
- the inner structure 16 is shown in the top view. In this illustration, the comparatively large surface area in relation to the height of the inner structure (see FIG. 1) is clear. This geometry is necessary because the cross section of the collecting space must not be narrowed excessively. In this way there is sufficient air supply to the intake ducts.
- FIG. 3 shows a section through the wall section of an inner structure 16.
- the wall thickness of the component increases linearly in this case.
- the bores 18, which are made at regular intervals in the wall and serve as necks for the shunt resonator, have a different length. As a result, the shunt resonator has a broadband effect.
- FIG. 4 schematically shows an inner structure 16 with a plurality of resonator spaces 23. These are formed by a partition wall 26, which is located on the inner wall 17 of the Supports the suction pipe.
- the inner structure can have a circumferential lip 27 with the
