Abstract:
A method of controlling an exhaust gas temperature at a particulate filter inlet is disclosed. The particulate filter is located in an exhaust system of an internal combustion engine. The method of controlling exhaust gas temperature at the particulate filter inlet includes a late injection, whose quantity is estimated as function of an exhaust gas volumetric flowrate.
