Beschreibung
Zusammenfassung:	Systems and apparatuses include an engine having a cylinder and a dedicated cylinder, an air intake system providing fresh air to the engine, a fueling system providing fuel to the cylinder and the dedicated cylinder, an exhaust gas recirculation pathway from the dedicated cylinder to the air intake system, and a controller structured to control the fueling system and the air intake system to provide a lean air-to-fuel mixture to the dedicated cylinder during a low-load condition, and to provide a rich air-to-fuel mixture to the dedicated cylinder after a tip-in event.
