Exhaust gas treatment device regeneration inhibiting fuel combustion in an engine cylinder

摘要

A method for an exhaust gas treatment device (8) in an engine system, and an engine system comprising an internal combustion engine with at least one cylinder (2) are presented. The engine system further comprises fuel injection means (11) and an exhaust gas treatment device (8). The method comprises performing a fuel injection exhaust gas treatment device regeneration (207), comprising inhibiting combustion in the at least one cylinder (2), and controlling the fuel injection means (11) so that fuel is allowed into at least one of the cylinders (2).
