Exhaust gas waste gate system with charge pressure control

In one aspect, an internal combustion engine (12) may include at least one turbocharger (18) having an exhaust gas inlet and a turbine (20). An exhaust gas channel may be connected to the exhaust gas inlet of the turbocharger (20). In the exhaust gas system a valve (336) may be provided that has a valve member (150). The valve may regulate exhaust gas directed to the turbine (20). The valve position may be controlled in response to a characteristic indicative of charge pressure of combustion air. In another aspect, a method may be provided for regulating the pressure of charged air delivered by a turbocharger (18) of an internal combustion engine (12). The method may include regulating the exhaust gas that is directed to the turbine (20) of the turbocharger (18) in response to a characteristic indicative of a charge pressure of charged combustion air. In another aspect, a valve (336) for regulating exhaust gas directed to the turbine may be provided.
