摘要： A method and an apparatus are described for the simultaneous adjustment of an air intake stream 24 of an internal combustion engine 10 and of a secondary air stream 21 into the exhaust system 12 of the internal combustion engine, the secondary air stream being produced by a compressor 20 which is driven by a turbine 18. The turbine 18 is housed in a bypass duct 16, the bypass duct being arranged parallel to a throttle valve 14 in the air intake tract 11 of the internal combustion engine. Thus the required amount of secondary air 21 is dependent upon the throttle valve setting. To create compensation for this, a control valve 32, for example, is created, which is connected through a connecting duct 4 to the secondary air duct 22. The control valve affects the cross section of the bypass line 16, so that in the event of an opening of the throttle valve 14 the cross section of the bypass duct can be expanded simultaneously, so that the pressure drop at the turbine, produced by throttle valve opening can be compensate. Alternatively the arrangement of a control valve is possible, which is operated by a control unit. Moreover, a mechanical coupling of the throttle means in the bypass line and the throttle valve is possible. The proposed method achieves the simultaneous adjustment of air intake flow and secondary air flow with reasonable design expense and therefore constitutes an economical solution.

摘要： A filter arrangement with a cellular structure in which a plurality of filter chambers extend in the direction of the medium to be filtered. There is a filter cloth or fabric attached to each of the two sides of a cell frame which closes the filter chambers on both sides. The filter chambers are each provided with a filling of predominantly active charcoal granules. To achieve a simple and advantageous structure of the filter arrangement, the cellular structure is in the form of a rectangular cell frame each with rectangular filter chambers, preferably made of synthetic resin. Appropriate, right-angled partition walls inside the cell frame and the installation of reinforcement members can result in filter chambers of optimum size.
