The present invention improves the operation of an exhaust gas recirculation system having a recirculation combustion chamber or group of combustion chambers dedicated to supplying recirculated gas. Once a sensed engine load is within a predefined range, a controller advances fuel injection into the recirculation combustion chamber to reduce formation of particulates. The reduction in particulates reduces fouling of an exhaust gas recirculation system.

[ What is claimed is:] [1.] A method of operating an exhaust gas recirculation system for an internal combustion engine, comprising the steps of:determining an engine load condition;directing exhaust gas from a first group of combustion chambers to an exhaust gas recirculation system where said engine load condition being above a predetermined range, said first group being less than all of a plurality of combustion chambers of said engine;directing exhaust gas from a second group of combustion chambers to an exhaust system; andadvancing injection of fuel into said first group where said engine load condition being above said predetermined range, said advancing being adapted to promote mixing of fuel and air.
