摘要：
A method of controlling an exhaust gas treatment system of a vehicle includes detecting a request to regenerate a particulate filter, and injecting hydrocarbons at an injection rate into a flow of exhaust gas upstream of an oxidation catalyst to heat the oxidation catalyst. The injection rate is increased at a current acceleration rate, and the current acceleration rate is reduced to define a reduced acceleration rate when the oxidation catalyst is quenched.
