Abstract

Systems and methods for increasing an amount of fuel injected into a dedicated exhaust gas recirculation (EGR) cylinder in an engine are disclosed. In one example approach, a method comprises, prior to combustion, injecting a first amount of fuel to a dedicated EGR cylinder, and after combustion and during an expansion and/or exhaust stroke, directly injecting a second amount of fuel to the dedicated EGR cylinder.
