Abstract
A method and system for managing temperatures in an exhaust system of a motor vehicle is disclosed. The method includes a step of predicting an overheat condition of a catalyst and a seal mat included in a catalytic converter. The method also includes a step of selecting a fuel enrichment map to determine a fuel delivery amount based on a predicted overheat condition. The method and system further includes providing a fuel enrichment map for an overheat condition of a catalyst that includes fuel delivery amounts that are less than fuel delivery amounts included in a fuel enrichment map for an overheat condition of a seal mat.
