Abstract

Provided is an exhaust system for an internal combustion engine comprising: a first exhaust conduit leading from a first exhaust bank of the engine to a first turbocharger turbine inlet arranged downstream of the first exhaust bank in the direction of travel of a first exhaust stream; a second exhaust conduit leading from a second exhaust bank of the engine to a second turbocharger turbine inlet arranged downstream of the second exhaust bank in the direction of travel of a second exhaust stream; an SCR catalyst arranged downstream of the first turbocharger turbine inlet and/or second turbocharger turbine inlet; and a reductant supply system comprising a distributor pipe and a reductant injector. The distributor pipe is configured to fluidly connect the first exhaust conduit to the second exhaust conduit upstream of the first turbocharger turbine inlet and second turbocharger turbine inlet, and the reductant injector is configured to supply a reductant to the distributor pipe.
