Patent ID: 7252064

Claim:
A switchable air intake system for a multicylinder internal combustion engine, comprising: at least one short intake manifold; at least one long intake manifold; and a regulating element for controlling cross sections of the respective intake manifolds as a function of operating parameters; wherein, the at least one short intake manifold for a first cylinder bank row and the at least one long intake manifold for a second cylinder bank row of the internal combustion engine are controllable by a single joint regulating element; the joint regulating element comprises a rotary slide valve; the at least one short intake manifold assigned to the first cylinder bank row and the at least one long intake manifold assigned to the second cylinder bank row intersect; and the joint rotary slide valve is situated in an intersection area of the short and long intake manifold such that, depending on the position of the rotary slide valve, the at least one short intake manifold is opened while the at least one long intake manifold is closed, or vice versa.
