    摘要： A method is disclosed for controlling a two-stage turbocharger system having low-pressure and high-pressure turbochargers in line, sequentially, with an engine. The turbochargers include a low-pressure (LP) turbine and an LP compressor, and a high-pressure (HP) turbine and an HP compressor. The LP compressor feeds the HP compressor, which feeds the engine intake. The engine exhaust feeds the HP turbine, which feeds the LP turbine. The method determines a total boost pressure, which provides combustion reactant for the engine. The method calculates an LP compressor power from the determined total boost pressure, and an LP turbine flow from the LP compressor power. The low-pressure turbocharger operates at the calculated LP turbine flow. The method calculates an HP compressor power from the determined total boost pressure, and an HP turbine flow from the HP compressor power. The high-pressure turbocharger operates at the calculated HP turbine flow.

    摘要： A method and a device for operating a sensor is provided in an exhaust gas system of an internal combustion engine for determining the emissions contained in an exhaust gas flow, in particular, of nitrogen oxides, ammonia, oxygen and/or unburnt carbon, with the exhaust gas flow acting on the sensor during measurement phases. Between the measurement phases, the sensor is at least largely kept free from the exhaust gas flow, wherein the duration and/or the frequency of the measurement phases can be set as a function of operating parameters of the internal combustion engine and/or of the exhaust gas regulation system. A measurement space which surrounds the sensor is exposed to a pressurized flushing gas immediately after a measurement phase, as a result of which the exhaust gas present in the measurement space is displaced out of the measurement space into the exhaust gas flow.
