Abstract
The systems and methods herein relate the operation of a particle filter which is arranged in an exhaust-gas path of an internal combustion engine, to a device for exhaust-gas aftertreatment which can be operated in accordance with the method that comprises determining a mass flow rate of an exhaust-gas flow flowing in the exhaust-gas path; and supplying ambient air into the exhaust-gas path as a function of the determined mass flow rate. By this method, the spontaneous regeneration of a particle filter within the exhaust system may be abated.
