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).
