Abstract
An exhaust system for a turbocharged internal combustion engine comprises a first exhaust conduit extending between a first engine cylinder and a turbocharger inlet and is configured to conduct exhaust gas therebetween. A second exhaust conduit extends between a second engine cylinder and an in inlet for an exhaust gas recirculation system and is configured to conduct exhaust therebetween. An exhaust gas bypass extends between, and is in fluid communication with, the first and second exhaust conduits and is configured to divert exhaust gas flowing through the second exhaust gas conduit to the first exhaust gas conduit, and the turbocharger inlet, under conditions of varying exhaust gas recirculation demand of the internal combustion engine.
