Abstract
An exhaust control system comprises an absorption rate estimation module, a desorption rate estimation module, a rate of change module, a release rate estimation module, and a fuel control module. The absorption rate estimation module estimates a hydrocarbon energy absorption rate of a component of an exhaust system. The desorption rate estimation module estimates a hydrocarbon energy desorption rate of the component. The rate of change module that determines a stored energy rate of change based on a difference between the hydrocarbon absorption and desorption rates. The release rate estimation module estimates a hydrocarbon energy release rate for the component based on the stored energy rate of change. The fuel control module controls a rate of fuel injection into the exhaust system upstream of an oxidation catalyst based on the hydrocarbon energy release rate.
