A method for reducing engine deposits in an internal combustion engine, using selective fuel and EGR supply scheduling, is provided including an engine having a first and second plurality of cylinders. A fuel injection system for injecting fuel into both of the first and second plurality of cylinders is located on the engine. An exhaust gas recirculation system supplies a portion of the exhaust gases from the engine to both of the first and second plurality of cylinders. During operation, the engine repeatedly combusts fuel in both of the first and second plurality of cylinders. Additional fuel is supplied to one or more selected cylinders following each combustion cycle while recirculated exhaust gases are supplied from a remaining plurality of cylinders, preventing interaction of post-combustion injected and recirculated exhaust gases and reducing deposition of undesirable material.
