Abstract
A system comprises an injection control module and a fuel film module. The injection control module controls a flow rate of fuel injected into an exhaust system to adjust a temperature of exhaust gas. The fuel film module determines an accumulation rate of fuel on a surface of the exhaust system based on the flow rate of the fuel. The fuel film module determines a release rate of fuel from the surface of the exhaust system based on a flow rate of the exhaust gas. The injection control module adjusts the flow rate of the fuel based on the accumulation rate and the release rate.
