Abstract
Various methods and systems are provided for regeneration of an exhaust gas recirculation cooler. One example method includes adjusting cooling of exhaust gas by an exhaust gas recirculation cooler to maintain a manifold air temperature during an idle condition of an engine. The method further includes initiating regeneration of the exhaust gas recirculation cooler during the idle condition when an effectivity of the exhaust gas recirculation cooler falls below a threshold effectivity prior to or during the idle condition.
