An engine configuration includes an internal combustion engine with a plurality of cylinders, at least one turbocharger and a first and a second exhaust gas tract. A turbine of the at least one turbocharger is associated with the first exhaust gas tract. Increased torque and increased power can be achieved when a bypass exhaust gas line emerging from at least one cylinder, which is associated with the first exhaust gas tract, is connected to the first exhaust gas tract such that it bypasses the at least one turbocharger.

Engine configuration including an internal combustion engine

To reduce fuel consumption and exhaust emissions in an internal combustion engine a comparatively large quantity of exhaust gas is recirculated and a specific swirling flow is imposed on the exhaust gas as it is introduced into the combustion chamber. For this purpose the exhaust duct has a chamfer formed on only one side in the region of a flow cross-section. The swirling flow of exhaust gas rotating about an axis parallel to the cylinder axis, together with the supply of fresh gas, assures an increased fresh-gas concentration in the region of the spark plug.
