Abstract
A method for controlling an engine with exhaust gas recirculation is provided. The method comprises directing EGR from exhaust downstream of an exhaust-aftertreatment catalyst to mix with fresh air upstream of an intake compressor and upstream of a throttle valve, and, in response to increased throttling by the throttle valve, discharging the mixed EGR and fresh air from downstream of the intake compressor to the exhaust downstream of the exhaust-aftertreatment catalyst.
