Abstract: A process and device are disclosed for controlling air consumption in the intake tract of an internal combustion engine. Air intake in the intake tract (2) can be subdivided via at least two ram tubes (3, 4). The intake path can be continuously controlled in one of the ram tubes (4) between a totally open state and a closed state and prolong the other ram tube (3). The ram tube (4) in which the intake path can be continuously controlled between a totally open state and a closed state is preferably the shortest ram tube (4).

Abstract: To overcome problems concerning the sticking of the check plate in a combined check and control valve, a stop is provided on the valve rod or a guide element in the vicinity of the valve rod, whose distance to the limiting element is smaller than the maximum stroke and larger than the nominal stroke of the limiting element. Thus, it is achieved that the check plate is released from the valve seat by means of the stop, when the valve rod is displaced to the maximum.

Abstract: 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.

Abstract: A duct system suitable for use as an intake manifold for an internal combustion engine, including flap valves (13) for selective opening and closing of the ducts. The positions of the valves are continuously adjustable in order to produce a swirl in the flow of combustion air. To achieve this, a high degree of angular precision is required in the positioning of the valves. Intake manifold manufacturing tolerances need to be compensated during assembly of the valves. A valve adjusting mechanism is provided in mechanical couplings (23) of the valve linkage between the position adjusting motor (19) and the flap valves (13).
