Definitions
- the invention relates to air gap-insulated exhaust manifolds for internal combustion engines according to the preamble of claim 1.
- Air gap insulated exhaust manifolds essentially comprise a manifold for the engine exhaust, consisting of an inner and an outer shell construction, which are isolated from each other by an air gap. This collecting housing is also provided with a plurality of flanges, which connect to the corresponding outlets of the cylinder head of the internal combustion engine. Air gap insulated exhaust manifolds are prior art, especially in motor vehicles equipped with catalytic converters.
- a catalyst requires a relatively high minimum temperature in order to efficiently carry out the exhaust gas conversion. This so-called light-off temperature is about 250 0 C.
- the hot exhaust gases flowing from the cylinder chamber into the exhaust manifold after engine start, which are then forwarded for conversion into the catalyst are themselves the only heat source for activating the catalyst.
- the thin-walled wall panel of the inner shell structure in the exhaust manifold quickly reaches the exhaust gas temperature of up to 900 0 C, without withdrawing the exhaust gas flow significantly heat.
- the heat losses to the outer shell and thus finally kept small in the engine compartment by the insulating acting air gap The outer shell of the exhaust manifold does not exceed a temperature of 500 0 C even with prolonged engine operation.
- Critical areas for unwanted heat losses on the inner shell and thus also heat losses of the exhaust gas flow are the areas where the inner shell in direct contact with the colder outer shell and especially the considerable colder flanges, which are approximately the temperature of the water-cooled cylinder head of max. 120 0 C is located. The reason for this is that in these areas the heat transfer takes place by heat conduction. From the warmer inner shell, the heat flows by transferring the kinetic energy of the atoms to the colder outer shell, or to the colder flanges.
- the present invention has for its object to construct an exhaust manifold so that the inner shell for a fixed, that is stored vibration-free and that on the other hand, the thermal expansion of the inner shell relative to the flange and outer shell, especially in the temperature changes in the phase shortly after Start and stop of the engine, is made possible without these thermal expansions have a negative impact on the vibration-free mounting of the inner shell.
- An essential advantage of the exhaust manifold according to the invention is that it consists of only three components: the flange, a hood-shaped outer shell, which is connected via its peripheral collar with the flange, and an inner shell, which has the same hood-shaped shell shape as the outer shell and with her Collar between the collar of the outer shell and the flange is clamped.
- Characteristic feature of the present invention is that the inner shell is clamped by bulges along its collar surface between the outer shell and the flange in a fixed, defined position. So there are no other parts such as fasteners or sealing devices necessary.
- the outer shell is welded or soldered to the flange. In the case of soldering the flange is formed as a sheet metal part, which is crimped at the edges around the edge of the outer shell.
- FIG. 3 shows a cross section through the exhaust manifold of FIG. 1 according to a second embodiment
- 4 shows a cross section through the exhaust manifold of FIG. 1 according to a third embodiment
- FIG. 5 shows a longitudinal section through the exhaust manifold of FIG. 4 along the line IV-IV in Fig. 4,
- FIG. 6 shows a cross section through the exhaust manifold of FIG. 1 according to a fourth embodiment
- FIG. 9 shows a longitudinal section through the exhaust manifold of FIG. 8 along the line IX-IX of Fig. 8 and
- FIGS. 2 to 8 each show, in the form of longitudinal and / or cross sections, various embodiments of the positionally fixed attachment of the inner shell in the area between outer shell and flange.
- a flange 11 which is attached to a cylinder head of the internal combustion engine, not shown, is covered on the gas outlet side with a gas-tight outer shell 20, in turn an inner shell 30 is introduced.
- the design of the outer shell 20 does not change. It is formed of sheet metal (eg 2 mm wall thickness) and consists of a hood-shaped upper part 21, to which a circumferential collar 22 connects, which is connected to the flange 11.
- the design of the outer shell collar 22 is also a characteristic feature of the present invention: it consists of a directly adjacent to the dome-shaped sheet metal upper part 21, inner collar segment 22 ', which extends parallel to the surface of the flange 11, and from a via an oblique Sheet segment 23 subsequent, outer collar segment 22 ", which rests on the flange 11, and is connected to it by welding or soldering.
- the inner shell 30 has in its hood-shaped upper part 31 the same contour as the upper part 21 of the outer shell 20, with the obvious difference that it is due to their smaller dimensions at a distance of an air gap within the upper part 21 of the outer shell 20.
- the inner shell collar 32 lies in all embodiments according to Figures 2 to 10 in the air gap between the inner outer shell collar 22 'and flange 11.
- the embodiments in FIGS. 2 to 10 differ only in the geometry of the inner shell collar 22, the design of the flange 11 and in the introduction of additional clamping or guide elements in the collar area (wire rings 40 and additional sheet 50).
- Fig. 2 shows an exhaust manifold 10 in cross-section, which has an inner shell 30, the collar 32 rests on the flange 11 and protrudes into the air gap between the inner outer shell collar 22 'and flange 11.
- the firm clamping of the inner shell is achieved in that the inner shell collar 32 on its outer edge from the collar surface upwards in the direction of the inner outer shell collar 22 'exiting bulges 33 which rest on the inner outer shell collar 22' punctiform under pressure.
- the inner shell 30 between the outer shell 20 and flange 11 is firmly clamped punctiform.
- the hot gases emerging through the flange opening 13 from the cylinder, not shown, cause a thermal expansion of the gas-carrying inner shell 30.
- Fig. 3 shows a modification of the inner shell construction shown in Fig. 2.
- the inner shell collar 32 rests against the inner outer shell collar 22 'and the bulges 33 on the edge of the inner shell collar 32 are consequently formed on the lower side, the flange side, in the form of a nub in punctiform contact with the flange 11.
- exhaust gas could flow into the air gap between inner outer shell collar 22 "and flange 11 from the gas-carrying inner shell 30 through the space between the bulges 33.
- FIG. 4 shows an embodiment in which the inner shell collar 32 is placed centrally in the air gap between inner outer shell collar 22 "and flange 11, without forming an unfavorable wide bearing surface with outer shell 30 or flange 11.
- the positionally stable support of the inner shell 30 thereby becomes achieved that the bulges 33 are formed on both sides of the edge of the inner shell collar 32 and so fix the inner shell 30 by punctiform support on the inner outer shell collar 22 "and the flange 11.
- This design is particularly loss, because here surface-like bearing surfaces between inner shell collar 32 and flange 11 and inner outer shell collar 22 'are not present, but the inner shell 30 is fixed only by punctiform support pads on the bulges 33 at the edge of the inner shell collar 32.
- FIG. 5 shows a longitudinal section along the line IV-IV through the bulges 33 of the inner shell collar of FIG. 4.
- the bulges 33 are distributed uniformly undulating at the edge of the inner shell collar 32 and are supported at the top of the outer shell collar 22 'and at the bottom of the flange 11.
- FIG. 6 shows the cross section of a further embodiment of the exhaust manifold 10.
- the inner shell collar 32 rests on the inner outer shell collar 22 'as shown in the embodiment in FIG.
- the bulges 33 of the inner shell collar 32 are as in Fig. 3 knob-shaped down against the surface of the flange 11 formed, but not at the edge of the inner shell collar 32 but somewhat indented, so that the bulges 33 still follows a straight, undeformed collar segment, the on the inner outer shell collar 22 'is applied.
- Fig. 7 shows a structure similar to the embodiment shown in Fig. 6. However, the bulges 33 do not extend to the surface of the flange 11.
- the fixed clamping of the inner shell 30 is achieved by wire rings 40 which are inserted between inner shell collar 32 and flange 11.
- the wire rings 40 are like this inserted, that the bulges 33 of the inner shell collar 32 are located between them, so that the wire rings 40 are thereby fixed in the transverse direction.
- the inner shell 30 is thus not clamped directly between the flange 11 and outer shell collar 22, but indirectly between the resting on the flange 11 wire rings 40 and the outer shell collar 22.
- the bulges 33 of the inner shell collar 32 act in this embodiment as guides for the wire rings 40th Die Drahtringe 40 serve not only as Verklemmungsetti for the inner shell 30 but also as guide elements along which the inner shell 30 can slide in thermal expansion. Another advantage is that the contact surface and consequently also the associated heat losses between wire rings 40 and gas-carrying inner shell 32 is small.
- FIG. 8 shows the cross section of a further embodiment, in which, according to the embodiment according to FIG. 4, the bulges 33 of the inner shell collar 32 unfolding the clamping effect are formed on both sides.
- the bulges 33 are formed at a distance from the edge of the inner shell collar 32 and the bulges 32 is still followed by a straight undeformed part of the inner shell collar 32.
- the flange 11 is here as the shells 20, 30 of the exhaust manifold 10 formed as a sheet metal part.
- the sheet metal of the flange 11 is crimped at its edges around the outer collar 22 'of the outer shell 20.
- This flanging has the advantage that flange 11 and outer shell 20 are held together, and that a soldering of the outer shell 20 with the flange 11 along the outer outer shell collar 22 'is possible.
- the sheet metal design of the flange 11 offers the advantage that the opening 13 of the flange 11 can be bent upwards into the exhaust manifold 10, wherein the diameter of the flange opening 13 easily merges, similar to a nozzle.
- This nozzle-like shape of the flange opening 13 offers the advantage that the heat of the exhaust gas is quickly led away from the flange 11.
- Fig. 9 shows a longitudinal section along the line IX-IX through the bulges 33 of the inner shell collar 32 in Fig. 8.
- the bulges 33 of the inner shell collar 32 are here uniformly wavy designed and supported alternately upwards against the inner outer shell collar 22 'and after down against the sheet-formed Flange 11 from.
- These protrusions 33 are always in contact only via small, almost punctiform zones with outer shell 20 and flange 11. Consequently, the heat losses by heat conduction remain low.
- FIG. 10 shows the cross section of a further embodiment in which the bulges of the inner shell collar 32 are formed at a distance from the edge and at one side upwards against the inner outer shell collar 22 '.
- the inner shell collar 32 does not lie on the flange 11 on the underside, but is guided centrally in the air gap between inner outer shell collar 22 "and flange 11.
- the position-resistant clamping is achieved by an additional plate 50 which is inserted between inner shell collar 32 and flange 11.
- 50 is also not over its entire surface on the relatively cold flange 11, but is by a similar shape design as the inner shell collar 32 only in point contact with the flange 11.
- the additional sheet 50 wherever the inner shell collar 32nd The additional sheet 50 has an opening 51 which coincides with the nozzle diameter of the flange opening 13.
- the edge surface of the opening 51 of the additional sheet 50 is flush with the inwardly tapered sheet metal of the flange opening 13
- the position-resistant clamping of the inner shell 30 thus takes place between the contact points of the bulges 33 of the inner shell collar 32 on the inner outer shell collar 22 'and the support of the inner shell collar 32 on the additional sheet 50.
- the inner shell collar 32 rests almost entirely on the additional sheet 50, the heat losses are still low because the additional sheet 50 in turn is only about its bulges 52 and the edge surface of its inner opening 51 with the cooler flange 11 in touch.
- a further advantage of this embodiment is that between additional sheet 50 and flange 11, a further air gap 60 is formed, which isolates the flowing through the flange opening 13 hot exhaust gas stream (temperature at about 900 0 C) from the surface of the flange 11.
- This is particularly advantageous because the flange 11 remains relatively cool even in the operating condition of the engine, since it is mounted flat on the water-cooled cylinder block (temperature up to 120 0 C). As a result, the undesired heat losses of the exhaust gas flow are further reduced by this embodiment.
