METHOD AND SYSTEM FOR CONTROLLING THE MASS FLOW DURING REGENERATION OF A PARTICLE FILTER IN A POST-TREATMENT SYSTEM OF A COMBUSTION ENGINE

摘要

The present invention relates to a method pertaining to regeneration of a particle filter (202) in a post-treatment system (200), which particle filter (202) is adapted to treatment of an exhaust mass flow arising from combustion in a combustion engine (101) which is supplied with air for said combustion. The method comprises the steps of - determining a representation of a temperature of the air supplied for the combustion, - determining a representation of a pressure of the air supplied for the combustion, and - on the basis of said representations of temperature and pressure of said air supplied for said combustion, controlling said engine (101) so that the magnitude of the exhaust mass flow arising from the combustion substantially corresponds to a first value.
