摘要： The invention relates to an air-routing system, especially a suction system of an internal combustion engine. The inventive system makes optimal use of the available installation space by integrating a bypass channel (25) into the suction module. The volume of the bypass channel also provides an acoustic shield for the collector chamber (22). The free screwing area (13) behind the fastening flange (11) that is required for mounting the suction module (11) is used by an air intake hood (14) which can be placed on the filter housing (15) after the suction module has been mounted. This ensures that there is a greater volume available in the filter housing (15), hereby reducing the muzzle noise on the air intake part of the suction module.

摘要： The invention relates to a filter cartridge, especially for the air filter of an internal combustion engine. Said air filter has an inlet for untreated air (12), an outlet for clean air (13) and a housing (10) for holding the filter cartridge (16). Said filter cartridge consists especially of a filter medium that is folded in a zigzag shape. The filter medium is provided with sealing elements on the front-end terminal plates (18, 19). A support body (17) is provided on the inner wall of the filter cartridge. Said support body has support surfaces (23) for axially and radially positioning the filter cartridge. A seal element (26) is also provided in the area of the support body (17), said seal element extending in an axial direction over said support body (17).
