A method of calibration of at least one fuel injector for a fuel burner in an exhaust gas treatment system for an internal combustion engine is therefore suggested. The inventive method is adapted for an exhaust gas system having said fuel burner mounted upstream of a diesel particle filter (DPF). The method of calibration is performed during an idle speed of the combustion engine, this to assure a constant temperature of the burner during the calibration. Hence, the method is started when a first steady temperature is registered in the fuel burner, wherein said at least one fuel injector, is operated with a first pulse width. A first temperature of an exhaust gas is registered directly downstream of the fuel burner. After this first temperature is registered, the pulse width of the fuel injector changed into a second pulse width, which is different from the first pulse width. |
