Definitions
- the invention relates to a method for producing an exhaust manifold for multi-cylinder Internal combustion engines.
- exhaust collector or manifold are called Components used. They cause the exhaust gases produced during combustion multiple cylinders into a cost-effective single-flow exhaust aftertreatment system, in particular for emission and noise reduction, to be transferred.
- Exhaust manifold In contrast to cast gas produced exhaust manifolds are built Exhaust manifold with or without catalysts usually from a larger number made of components.
- the state of the art includes in this context Exhaust manifold or exhaust manifold, as described in DE 195 10 602 C1 or the DE 43 39 290 C2 are described.
- EP 0 928 885 A2 includes an exhaust device for an internal combustion engine and a method for producing the exhaust device to the state of Technology.
- the exhaust device has a catalyst and double-walled leads for connecting exhaust gas exits of the internal combustion engine with the Catalyst.
- the exhaust device comprises two integral shells, of which each about half of the housing wall of the catalyst and half of the outer walls of the various leads forms. Each shell will be one originally flat sheet metal part formed by plastic forming. After that will be the shells welded together.
- From DE 44 44 759 A1 is a method and an apparatus for manufacturing an exhaust inlet port for a motor vehicle catalyst out.
- an outlet tube bulged hydraulically is an outlet tube bulged hydraulically. Subsequently, the deformed tube divided in the middle of the bulge by a diagonal cut. The resulting Hopper openings of the inlet or outlet are then to the catalyst housing welded.
- US 5 031 401 A further includes a reactor plant for the purification of from internal combustion engines escaping gas to the prior art. These has a housing having an innerliner and fibrous therein Material is provided.
- the collector housing provides a connection between the head flange, which at the multi-cylinder exhaust side of an engine is determined, and the tail flange connected to the usually single-channel exhaust dissipation system becomes. It is known in the collector housing catalyst components encase.
- the invention is based on the prior art, the object of a To show a method which is a cost-effective production of quality high-quality exhaust manifolds for multi-cylinder internal combustion engines allows.
- a first solution to this problem consists in a method according to claim 1.
- a tubular output profile is used, which in his Cross-sectional dimensions corresponds to the diameter of the later collector housing.
- the collector housing is formed by upstream of the inflow is made, for example, by bending and Pressure forming or embossing.
- the inflow channel receives a rectangular Cross-section with flattened longitudinal sides and rounded narrow sides.
- the collector housing are then the catalyst components from the outflow side built-in. Subsequently, the outflow channel is then formed.
- the second solution of the problem is characterized by a method according to claim 2.
- Core here is the production of the collector housing from a tubular output profile by hydroforming, wherein the inlet side of the inflow channel is made in which the initial or intermediate profile to a substantially rectangular cross section with rounded narrow sides is widened.
- the Inflow channel is an integral part of the collector housing.
- a catalyst is integrated in the collector housing.
- the header body is molded with the inflow channel.
- the catalyst system that is a carrier with Blähmatte, in the collector housing brought in. This process is technically also canning process called.
- the discharge channel is retracted by pressing and receives in this case a reduced relative to the cross section of the collector housing, essentially circular cross-section.
- the two independent solutions according to the invention enable the production of exhaust collectors, which may consist of a minimum of three components, namely the head flange and the header housing with molded outflow channel as well the catalyst.
- the exhaust collector does not have to be necessary from a circular Tube can be produced as output profile. Also oval or polygonal profile cross sections are usable. There is a cost savings because welding operations omitted. Also, the need for different tools for the production of individual components is lower.
- the durability of the exhaust manifold can be increased, in particular by the elimination of inhomogeneities, such as welds and overlaps.
- a shot flange is attached to the outflow channel (claim 4).
- the shot flange can be omitted.
- in the pressure shaping of the outflow channel could Bead be pressed to the collector's end. This can then be a form-fitting Connection, for example by a spring element, with the dissipative Exhaust pipe can be generated.
- the inflow channel passes through a curved Pipe section in the collector housing over.
- FIGS. 1 and 2 respectively designate an exhaust gas collector.
- the Exhaust manifolds 1, 2 correspond in their basic structure and method of production, so that corresponding components carry the same reference numerals.
- the exhaust manifolds 1, 2 are used in multi-cylinder internal combustion engines. About an exhaust manifold 1, 2 are formed during combustion Exhaust gases from the cylinders in a single-pass exhaust aftertreatment system transferred. The exhaust aftertreatment is used in particular for emission and noise reduction.
- An exhaust collector 1 or 2 has a collector housing 3, on which an inflow channel 4 and an outflow channel 5 is formed.
- the collector housing 3 can by Hydroforming of a tubular initial profile are formed. In this case, the collector housing 3 receives its bulbous cross-sectional configuration. Subsequently, the inflow channel 4 becomes a substantially rectangular Cross-section with rounded narrow sides 6 expanded. The cross-sectional configuration of the inflow channel 4 can be seen in dashed lines in the figure. 2 The expansion of the inflow 4 takes place with a tool, for example over a thorn.
- the collector housing 3 are also formed on a tubular output profile, which with its cross-sectional dimensions the diameter of the later collector housing 3 corresponds.
- the output profile Positionally fixed by an outer and / or inner support. Then receives the Inflow 4 its Querschntitskonfiguration by way of a train pressure operation as well as embossing and widening.
- the outflow channel 5 of the collector housing 3 is then retracted by pressing and thereby receives a reduced relative to the cross section of the collector housing 3, essentially circular cross-section.
- the collector housing 3 After the manufacture of the collector housing 3 only has a head flange 7th be welded to the inflow 4.
- inflow openings 8 In the head flange 7 are inflow openings 8 arranged for to be transferred from the cylinders of the internal combustion engine Exhaust gases.
- the exhaust manifold 2 In contrast to the exhaust manifold 1, the exhaust manifold 2 consists of only two Components, namely the collector housing 3 with integrally formed outflow channel and the welded-head flange 7. The discharge channel 5 is on the collector housing. 3 affiliated by pressing fed.
- the inflow channel 4 passes through a curved pipe section 11 into the collector housing 3.
