Abstract
For exhaust gas recirculation (EGR) fueling control, at least one donor cylinder of a plurality of cylinders in an engine provides exhaust gas to an air intake for the plurality of cylinders. A fuel variable restriction initially provides fuel concurrent with an intake stroke for the at least one donor cylinder in response to a transition from withholding the fuel to the plurality of cylinders.
