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 10):
A method comprising:\n providing a charge flow to an internal combustion engine having at least one primary exhaust gas recirculation (EGR) cylinder connected to an EGR passage and a plurality of non-primary EGR cylinders connected to an exhaust passage; passing an exhaust flow from the non-primary EGR cylinders through the exhaust passage; passing an EGR flow from the at least one primary EGR cylinder through the EGR passage to an intake system, the charge flow including an EGR fraction corresponding to an amount of recirculated exhaust gas in the charge flow from at least the at least one primary EGR cylinder; determining an EGR fraction reduction condition in the charge flow to the internal combustion in engine in response to a reduction of the EGR fraction from an expected EGR fraction; and in response to the EGR fraction reduction condition, reducing an air-fuel ratio to the at least one primary EGR cylinder.
