Abstract
A system for a vehicle includes a change determination module, a sulfur determination module, and a final equivalence ratio (EQR) module. The change determination module estimates a change in an amount of sulfur within a catalyst of an exhaust system of the vehicle. The sulfur determination module estimates the amount of sulfur within the catalyst based on the change. The final EQR module selectively adjusts fueling of an engine based on the amount of sulfur.
