Abstract
The invention relates to an air-intake duct system () in which a throttle valve (), an exhaust gas recirculating valve (), a bypass valve (), an exhaust gas cooler (), against which exhaust gas flows via bypass valve (), and, optionally, an air mass sensor are integrated. A complete intake unit for modern engines is hereby created, with which achieves a charging optimization and thus a reduction in fuel consumption as well as a reduction in pollutants by a corresponding thermal management in the engine by the exhaust gas cooler () that, together with a shell () of the housing (), is manufactured as a single piece. The individual add-on pieces () are optimally matched to one another and have, due to their designs, a low weight and a low finishing work requirement. This makes it possible to distinctly reduce assembly and manufacturing costs.
