The invention involves an engine system and a method for an engine system comprising an internal combustion engine comprising at least one cylinder, and an exhaust system comprising an exhaust gas treatment device, in which engine system the admittance of air and fuel is controllable by means of air flow control means and fuel control means, the method comprising performing an exhaust gas treatment device regeneration. The method comprises controlling, during the exhaust gas treatment device regeneration, the air flow control means and the fuel control means so as to provide a mixture to the exhaust gas treatment device with a lambda value of at least 1.0.
