| 1. A system for controlling engine emissions for an engine with exhaust gas recirculation, the system comprising:
means for detecting, in exhaust gas of the engine, at least one of: particulate matter and oxides of nitrogen;
means for predicting an intake composition for a next cylinder firing of the engine;
means for adjusting at least one engine parameter to compensate for the predicted intake composition, in order to minimize
variations in cylinder to cylinder emissions of at least one of: particulate matter and oxides of nitrogen.
