Exhaust gas recirculation system for an internal combustion engine

An exhaust gas recirculation system in a pressure-charged internal combustion engine, said pressure-charged internal combustion engine including an intake air circuit having an intake air pressurizing device, an intake manifold, an exhaust manifold, a plurality of combustion chambers, said exhaust gas recirculation system comprising:

• an exhaust gas recirculation conduit for diverting a flow of exhaust gas from at least one selected combustion chamber to said intake air circuit at a location downstream of said intake air pressurizing device;
• at least one exhaust gas recirculation diversion valve interposed between said selected combustion chamber and said exhaust gas recirculation conduit;
• a controller operatively associated with said exhaust gas recirculation diversion valve and adapted for selectively diverting said flow of exhaust gas from said selected combustion chamber to said exhaust gas recirculation conduit;
• and
• an intake air bypass conduit in fluid communication with said intake air circuit for selectively transporting a flow of intake air from said intake circuit to said exhaust manifold.
