Abstract:
A turbocharged internal combustion engine, comprising: a turbocharger including an axial flow turbine driven by a flow of exhaust gases generated by the engine, and an air compressor driven by the turbine for supplying combustion air to the engine, the turbine having stator blades defining nozzle throats positioned upstream of rotor blades; and a diverter valve operable for diverting a part of the flow of exhaust gases away from an inlet of the turbine to a location in the turbine downstream of the inlet, the diverter valve and the turbine being connected to divert the part of the flow of exhaust gases into a turbine region located downstream of the throats of the nozzles and upstream of the rotor blades.
