Abstract: Systems and methods for implementing regeneration of an aftertreatment component using exhaust gas recirculation is described. According to various embodiments, an engine system comprises an engine, a turbocharger, a fluid control valve, and a lean NOx catalyst. The engine has a first set cylinders fluidly coupled to an intake manifold and a second set of cylinders having fluidly isolated from the intake manifold of the engine. The fluid control valve is disposed between the first exhaust outlet and the exhaust conduit and is structured to selectively fluidly couple the first exhaust outlet to the exhaust conduit. Also, the lean NOx catalyst has an inlet structured to receive exhaust gases from the exhaust conduit at a position downstream of the turbine outlet and the fluid control valve.
