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 NO x  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 NO x  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.

Claim (Index 14):
A controller for use in an engine system, the controller comprising:\n an exhaust conditions module structured to interpret a current exhaust lambda value of exhaust gases from the engine system, the engine system comprising:\n an engine having a first set of cylinders having a first exhaust outlet fluidly coupled to an intake manifold of the engine and a second set of cylinders having a second exhaust outlet fluidly isolated from the intake manifold of the engine; \n a turbocharger having a turbine inlet fluidly coupled to the second exhaust outlet and a turbine outlet fluidly coupled to an exhaust conduit; \n a fluid control valve disposed between the first exhaust outlet and a the exhaust conduit, the fluid control valve structured to selectively fluidly couple the first exhaust outlet to the exhaust conduit; and \n an aftertreatment component having an inlet structured to receive exhaust gases from the exhaust conduit at a position downstream of the turbine outlet and the fluid control valve; \n a regeneration schedule module structured to interpret an exhaust lambda target value; and a regeneration module configured to operate the fluid control valve in response to the current exhaust lambda value and the exhaust lambda target value.
