Disclosed is an Exhaust Gas Recirculation (EGR) arrangement for an internal combustion engine 11 with sequential turbocharger, arrangement comprising a low pressure exhaust gas recirculation duct linking a position downstream of turbocharger turbines 13, 14 to a location between a first turbocharger compressor 25 and a second turbocharger compressor 26, i.e. a location downstream from one compressor and upstream of the other. The EGR duct may also have a branch to the turbocharger compressor inlet and a suitable flow control valve. A non-return valve may be provided in the EGR duct at a suitable location. A high pressure exhaust gas recirculation duct may also be provided. |
