Definitions
- the invention relates to a method for producing an exhaust manifold for multi-cylinder internal combustion engines.
- Exhaust gas collectors or manifolds are also called on internal combustion engines Components used. They cause the resulting from the combustion Exhaust gases from multiple cylinders into one inexpensive single-flow System for exhaust gas aftertreatment, especially for emission and Noise reduction to be transferred.
- exhaust manifolds In contrast to exhaust manifolds produced by casting, they are built Exhaust collectors with or without catalysts usually from one manufactured a larger number of components.
- the state of the art includes in this connection exhaust manifold or exhaust manifold, as in the DE 195 10 602 C1 or DE 43 39 290 C2 are described.
- the collector housing provides a connection between the head flange, the is fixed on the multi-cylinder exhaust side of an engine, and the end flange, to which the discharge pipe is usually single-channel Exhaust system is connected. It is known to be in the collector's housing To house catalyst components.
- the object of the invention is based on the prior art based on demonstrating a method which is inexpensive to manufacture of high-quality exhaust gas collectors for multi-cylinder internal combustion engines allows.
- a first solution to this problem consists in a method according to claim 1.
- a tubular starting profile is used, which in its cross-sectional dimensions the diameter of the later Corresponds to the collector's housing.
- the collector housing is attached to this starting profile formed by producing the inflow channel on the inflow side is, for example by bending and pressure forming or embossing. in this connection the inflow channel has a rectangular cross section with flattened Long sides and rounded narrow sides. In such a collector can then install the catalyst components from the outflow side become. The outflow channel is then formed.
- the second solution to the problem is a method according to claim 2 characterized.
- the core here is the production of the collector housing from a tubular one Initial profile by hydroforming, with the Inflow channel is made in which the initial or intermediate profile to a substantially rectangular cross-section with rounded narrow sides is expanded.
- the inflow channel is an integral part of the Collector housing.
- the two independent solutions according to the invention enable the Production of exhaust gas collectors that consist of at least two components can, namely the head flange and the collector housing with molded Outflow.
- the exhaust manifold does not necessarily have to be off a circular tube as a starting profile. Also oval or polygonal profile cross sections can be used. It will save you money achieved because welding operations are eliminated. Also the need for different Tools for the production of individual components is less.
- Exhaust collectors can be produced with the method according to the invention are used for designs with and without catalytic converters.
- the durability of the exhaust manifold can be increased in particular by eliminating inhomogeneities such as welds and Overlaps.
- the collector housing with the inflow channel shaped.
- the catalyst system that is, a support Inflatable mat, placed in the collector housing.
- This process is terminological also called canning process.
- the outflow channel pulled in by pressing and receives one opposite reduced the cross section of the collector housing, substantially circular Cross section as provided in claim 4.
- the head flange has to be used be determined on the inflow channel (claim 5). This is preferably done through a welding process.
- a weft flange is added to the outflow channel (claim 6).
- the No flange is required.
- the printing of the Outflow channel a bead are pressed to the collector end.
- About here can then be a positive connection, for example by a Spring element, are generated with the exhaust pipe.
- the inflow channel passes through curved pipe section into the collector housing.
- FIGS. 1 and 2 respectively denote an exhaust manifold.
- the exhaust manifolds 1, 2 correspond in their basic structure and Production method, so that corresponding components are the same Wear reference numbers.
- the exhaust manifolds 1, 2 come in multi-cylinder internal combustion engines for use.
- An exhaust manifold 1, 2 is used for combustion resulting exhaust gases from the cylinders in a single-flow system Exhaust gas treatment transferred.
- the exhaust gas aftertreatment serves in particular for emission and noise reduction.
- An exhaust manifold 1 or 2 has a collector housing 3, on which a Inflow channel 4 and an outflow channel 5 is formed.
- the collector's housing 3 can by hydroforming a tubular starting profile be formed.
- the collector housing 3 gets its bulbous Cross-sectional configuration.
- the inflow channel 4 becomes an essentially rectangular cross section with rounded narrow sides 6 expanded.
- the cross-sectional configuration of the inflow channel 4 recognizes one in dashed lines in Figure 2.
- the expansion of the Inflow channel 4 is carried out with a tool, for example via a Mandrel.
- this can Collector housing 3 also formed on a tubular starting profile which, with its cross-sectional dimensions, the diameter of the later collector housing 3 corresponds.
- the starting profile In the area of the collector's housing 3 is the starting profile by an outer and / or inner support fixed in position.
- the inflow channel 5 then receives its Cross-section configuration by means of a pull-pressure operation and embossing and expanding.
- the outflow channel 5 of the collector housing 3 is then pressed moved in and receives one compared to the cross section of the Collector housing 3 reduced, substantially circular cross-section.
- 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 molded outflow channel and the welded head flange 7. The outflow channel 5 is attached to collector housing 3 pulled in by pressing.
- a catalyst or catalyst components be integrated into the collector housing 3.
- the Collector housing 3 shaped, the catalyst system introduced and then the outflow channel 5 is drawn in by pressing.
