Abstract

An air intake system with resonance as well as ram charging. Ram charging is effected via intake ducts 15 and ram manifold 13, whereas resonance charging is effected by longitudinally adjustable resonance channels 12 and resonance manifold 11. The longitudinal adjustment of the resonance channels 12 is effected by rotatable control elements 22 driven by a motor 27, and the control elements 22 are accommodated in control housings 20 which communicate with the ram manifolds 13 via connecting ducts 34. The use of connecting ducts 34 allows a largely flexible arrangement of the control housings in relation to the intake manifold of the internal combustion engine. As a result the system can be advantageously and optimally adapted to the spatial characteristics within the engine compartment of a motor vehicle.
