Patent number: 6578537Abstract: An intake device for an internal combustion engine, comprising welded shells joined along a partition line, in which the partition line is provided with a region for producing inclined additional surfaces, which generate a transverse force Q2 due to their inclination relative to a pressure force D applied for welding the shells. This transverse force Q2 offsets a transverse force Q1 which is generated as a result of the inclination of partial regions of the partition line relative to the applied pressure force D. In this way, the transverse forces which arise during production of the intake device may be at least partially offset in the component, so that little or no forces are exerted on the molding tools, and the welding results for the intake pipe may thus be improved.Type: GrantFiled: May 31, 2002Date of Patent: June 17, 2003Assignee: Filterwerk Mann & Hummel GmbHInventors: Arthur Klotz, Ingo Koch, Herbert Pietrowski, Matthias Teschner

Patent number: 6474284Abstract: An air routing system, especially an air intake system of an internal combustion engine, which makes optimal use of available installation space by integrating a bypass channel (25) into an air intake module (10). The volume of the bypass channel also provides an acoustic shield for the collector chamber or plenum (22).

Patent number: 6357411Abstract: Branching pipes connect a surge tank to an intake manifold of an internal combustion engine. The branching pipes are made such that each gas column of the internal combustion receives a uniform intake volume. This is achieved by either making each branching pipe of the same length, or by adjusting the inside diameters of the branching pipes, thereby creating a flow delay of the intake into the gas columns, resulting in uniform intake volume. The inside diameters of the branching pipes are either made uniformly of a different diameter, or, alternatively, the inside diameters of the branching pipes include throttles for reducing the diameter of the branching pipe at a localized portion. In both cases, a flow delay of the intake into the gas columns is compensated, resulting in a uniform intake volume.Type: GrantFiled: December 29, 1999Date of Patent: March 19, 2002Assignee: Suzuki Motor CorporationInventor: Masahiro Aoki
