Abstract
Various methods and systems are provided for regenerating an exhaust gas recirculation cooler. One example method includes, routing exhaust gas from a donor cylinder group of an engine to an intake passage of the engine through the exhaust gas recirculation cooler, routing exhaust gas from a non-donor cylinder group of the engine to an exhaust passage of the engine, and adjusting fuel distribution among the donor cylinder group and the non-donor cylinder group responsive to a temperature of the exhaust gas recirculation cooler.
