Definitions
- the invention relates to an intake manifold for an internal combustion engine, the intake manifold having at least one engine-side flange, at least two tubular elements and at least one collecting space communicating with the tubular elements
- this object is achieved in that the collecting space of the suction pipe is divided into at least two communicating partial spaces by means of a separating element
- the intake manifold is made of plastic.
- the use of plastic makes the intake manifold lighter, thereby reducing fuel consumption
- the intake manifold is manufactured using half-shell technology. This manufacturing technology has cost advantages with simple geometries
- the separating element essentially comprises 100% of the collecting space cross-section.
- the separating element comprises 25 to 75% of the collecting space cross-section Cross-sectional constriction meets an air volume behind it, which acts as a spring.It is also important to ensure that the linear dimensions are small in relation to the wavelength, this avoids scattering in the area of cross-sectional constriction.It is also advantageous to elastically support the edge clamping of the separating elements the separating element entirely or partially made of porous material
- the distance from the separating element to the inner wall of the collecting space is not an integer divisible by the wave lengths occurring in the main operating state or a multiple thereof. This prevents standing waves from occurring
- An advantageous further development of the invention provides that the distance from the separating element to the inner wall of the collecting space can be changed.
- the occurrence of standing waves is prevented by the suitable selection of the geometry or its adaptation to the respective operating state, for example by means of movable partition walls by means of electrical devices or by elements supported by negative pressure prevented, since these arise precisely when a wave arrives at the starting point with the same phase after, for example, two reflections
- FIGS. 2a to 2e show embodiments of separating elements
- the pipe elements 3 all flow into the collecting space 4, which is halved by a separating element 5, shown schematically in FIG. 1.
- the intake pipe 1 is fastened by means of the holder 9 in the engine compartment, not shown, for example of a passenger car attached vacuum connection 10, the pressure conditions inside the intake manifold are recorded and used, for example, for control purposes.
- FIG. 1 a the typical weld seam 11 which, for example, connects the half-shell elements 6 and 7 to one another.
- This has the connection to the actual engine block (not shown here) Intake pipe 1 via a flange 2
- the pipe elements 3 all flow into the collecting space 4, which is halved by
- the intake manifold 1 shown in FIG. 1b has a flange 2 on the engine side, by means of which the intake manifold is fastened to the engine block of the internal combustion engine.
- This flange 2 on the engine side is connected to one by means of tubular elements 3, which in turn are composed of plastic half-shell elements 6 and 7 in this embodiment Connection space 4 connected, which in turn communicates with the air filter (not shown).
- the spatial expansion of this collection space 4 is restricted by a separating element 5 and is lined with a housing wall 8.
- This separating element 5 acts as a propagation barrier for vibration modes that are dependent on the operating state of the internal combustion engine.
- the intake manifold 1 is fastened in the engine compartment by means of the holder 9.
- the intake manifold 1 which is manufactured in half-shell technology in the exemplary embodiment described, has, as can be seen in FIG. 1b, the typical weld seams 11 on the intake manifold 1, injection valve receptacles 12 are provided, into which the injection valves, not shown, are inserted, and fastening holes 13, via which the intake manifold is attached to the engine block
- the entire intake manifold can also be made using the lost-melt technique, but this requires a certain complexity of the geometry, e.g. complicated inner contours, so that in the case of half-shell technology, several shells were necessary so that the cost situation of the manufacturing process for the lost-melt technique would have advantages
- FIGS. 2a to 2e Different configurations of separating elements 5 can be seen in FIGS. 2a to 2e
- the suction pipe 1 shown in FIG. 1a is shown in section, the separating element 5 shown covering almost the entire cross-sectional area of the collecting space 4
- FIG. 2b the suction pipe 1 shown in FIG. 1a is shown in section, the separating element 5 shown comprising only about a quarter of the cross-sectional area of the collecting space 4 Also shown are the weld seams 11, which, for example, connect the half-shell elements 6 and 7 are fastened the intake manifold 1 by means of the holder 9 in the engine compartment
- the suction pipe 1 shown in Figure 1 a is shown in section, wherein the separating element 5 comprises only half of the cross-sectional area of the collecting space 4 Also shown are the weld seams 1 1, which connect the half-shell elements 6 and 7, for example, are fastened Intake pipe 1 by means of the holder 9 in the engine compartment
- the suction pipe 1 shown in Figure la is shown in section, the separating element 5 comprises about a third of the cross-sectional area of the collecting space 4 Also shown are the welds 1 1, which connect the half-shell elements 6 and 7, for example, the suction pipe is fastened 1 by means of the holder 9 in the engine compartment
- the suction pipe 1 shown in Figure 1 a is shown in section, the separating element 5 shown covering approximately two thirds of the cross-sectional area of the collecting space 4 Also shown are the weld seams 11, which, for example, connect the half-shell elements 6 and 7 Intake pipe 1 by means of the holder 9 in the engine compartment
- the separating elements 5 shown in FIGS. 2b to 2e result in a reduction in the noise emission of the intake manifold, even if the cross section of the collecting space 4 is only reduced by 25 to 75%. On the one hand, this saves further material, which corresponds to a weight reduction, and on the other hand the air acts behind the separating element 5 like a spring on the air masses caused by the reduction in cross section caused by separating element 5 Another alternative is to be seen in the elastic mounting of separating element 5, which leads to a further reduction in the noise emission of the intake manifold 1.
- Another alternative, which is not shown in the drawing, provides that the distance from the separating element 5 to the housing wall 8 of the collecting space 4 can be changed by using either electromotively controlled elements which move the dividing wall 5 or by supporting the dividing wall 5 vacuum-moving elements, it becomes possible to set the ideal position of the partition 5 to the housing wall 8 of the collecting space depending on the respective operating state of the internal combustion engine
