Abstract
A method for operating an engine having a cylinder, an intake line for supplying charge air to the cylinder, and a device for controlling charge-air flows conducted via a charge-air cooler and via a bypass line around the charge-air cooler, comprises controlling the charge-air flows using the device, the device including a two-stage switchable shut-off element and a continuously adjustable shut-off element, wherein the two-stage switchable shut-off element, which is arranged parallel to the bypass line in the, is switched between only an open position and a closed position, and the bypass line is opened up or shut off to a greater or lesser extent by the shut-off element which is continuously adjustable between an open position and a closed position.
