An internal combustion engine includes at least one exhaust manifold and at least one intake manifold. A turbocharger includes a turbine, a first compressor and a second compressor. The turbine is connected with the exhaust manifold and has a controllable variable nozzle. The first compressor and the second compressor each are connected with and driven by the turbine. The first compressor has an inlet for receiving combustion air and an outlet. The second compressor has an inlet connected with each exhaust manifold and an outlet. A mixer interconnects the first compressor outlet and the second compressor outlet with the intake manifold. A controller is connected with and controls operation of the turbine variable nozzle, dependent upon an operating characteristic associated with the second compressor.
