Abstract
A method operates a particulate filter through which exhaust gas can flow in a vehicle, in which ash is introduced into a filter body of the particulate filter, wherein at least one ash former or at least one ash component is arranged on at least one carrier material upstream of the filter body in the direction of flow of the exhaust gas.
Claims24
A method of operating a particulate filter of a vehicle, through which particulate filter exhaust gas can flow, the method comprising:
- arranging at least one ash former or at least one ash constituent part at least indirectly on at least one carrier material upstream of a filter body of the particulate filter in a flow direction of the exhaust gas;
- and
- introducing ash into the filter body of the particulate filter via the at least one ash former or the at least one ash constituent part,
- wherein at least one of the carrier material and the ash former or the ash constituent part have two layers which provide at least one cavity from which the ash former or the ash constituent part is releasable into the filter body of the particulate filter.

A particulate filter for an internal combustion engine of a vehicle, comprising:
- a filter body for filtering particulates, which filter body can be flowed through by exhaust gas of the internal combustion engine;
- and
- at least one ash former or at least one ash constituent part arranged at least indirectly on at least one carrier material upstream of the filter body in a flow direction of the exhaust gas,
- wherein at least one of the carrier material and the ash former or the ash constituent part have two layers which provide at least one cavity from which the ash former or the ash constituent part is releasable into the filter body of the particulate filter.
