Abstract:
Systems, apparatus, and methods are disclosed that include a divided exhaust engine with at least one primary exhaust gas recirculation (EGR) cylinder and a plurality of non-primary EGR cylinders. The systems, apparatus and methods control the fueling to the at least one primary EGR cylinder in response to EGR fraction reduction conditions.

Claim (Index 17):
A system comprising:\n an internal combustion engine having at least one primary exhaust gas recirculation (EGR) cylinder connected to provide an EGR flow to an EGR passage and a plurality of non-primary cylinders connected to provide an exhaust flow to an exhaust passage, wherein the EGR passage is connected to an intake system to provide an EGR flow from the at least one primary EGR cylinder to the intake system, wherein the intake system provides a charge flow to the at least one primary EGR cylinder and the plurality of non-primary cylinders, the charge flow including an intake air flow and an EGR fraction provided by an amount of recirculated exhaust gas from at least the at least one primary EGR cylinder; and a controller configured to interpret an EGR fraction increase condition in which the EGR fraction provided by the amount of recirculated exhaust gas in the charge flow is increased from an expected EGR fraction during steady state conditions, and in response to the EGR fraction increase condition to increase an air-fuel ratio in the at least one primary EGR cylinder.
