  • Patent number: 8418679
    Abstract: The invention relates to a charger module (1) for an internal combustion engine, comprising a mechanical charger (2) and two charge coolers (3, 4), mounted downstream of the charger (2), for cooling the compressed charge air. The aim of the invention is to reduce the costs for producing such a charger module without impairing the rigidity or structural stability of the charger module (1). For this purpose, the charger (2) and the two charge coolers (3, 4) are inserted in a common housing (5) which surrounds the charger (2) and the two charge coolers (3, 4) at least on the bottom side and on two opposite sides.

  • Publication number: 20110302918
    Abstract: The invention relates to a motor vehicle with a combustion engine (10), from which exhaust gas is conducted to a turbine (16) of an exhaust-gas turbocharger (18), wherein exhaust gas can be diverted in flow direction of the exhaust gas upstream and downstream of the turbine (16) at respective withdrawal points (30, 32) and routed via a respective pipe system (34, 36) to an intake tract (38) for the combustion engine (10). It is hereby possible to cool exhaust gas routed into the intake tract (38) in a particularly simple manner and/or to adjust an amount of exhaust gas routed into the intake tract (38) in a particularly simple manner. The invention also relates to a method of operating a combustion engine (10) of such a motor vehicle, which method also allows to cool exhaust gas routed into the intake tract (38) in a simple manner and/or to adjust an amount of exhaust gas routed into the intake tract (38) in a simple manner.
