Abstract
Various methods and systems are provided for operating an internal combustion engine, the engine having a plurality of cylinders including one or more donor cylinders and one or more non-donor cylinders. In one example, a method includes, during an exhaust gas recirculation cooler heating mode, operating at least one of the donor cylinders at a cylinder load sufficient to increase an exhaust temperature for regenerating an exhaust gas recirculation cooler, and operating at least one of the non-donor cylinders in a low- or no-fuel mode.
