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 7):
An exhaust recirculation method comprising:\n receiving air in a first set of cylinders fluidly coupled to an intake manifold of an engine and a second set of cylinders fluidly isolated from the intake manifold; intaking a first ratio of an air/fuel mixture into the first set of cylinders; intaking a second ratio of an air/fuel mixture into the second set of cylinders, the second ratio of air/fuel mixture having a greater lambda value than the first ratio of air/fuel mixture; creating a combustion resulting in exhaust gas in the first set of cylinders and the second set of cylinders; routing the exhaust gas created by the combustion in the first set of cylinders to the intake manifold to be received by the engine; routing the exhaust gas created by the combustion in the second set of cylinders through an exhaust manifold fluidly coupled to the second set of cylinders towards an aftertreatment component downstream the exhaust manifold; and periodically routing the exhaust gas from the first set of cylinders towards the aftertreatment component to regenerate the aftertreatment component.
