A control device and a method for controlling an exhaust gas aftertreatment system comprising a diesel particulate filter is provided. The method comprises a step of, in response to a determination that a temperature of an exhaust gas entering the diesel particulate filter is equal to or below 325° C., controlling a NOx concentration of the exhaust gas entering the diesel particulate filter to be equal to or less than 600 ppm. An exhaust gas aftertreatment system as well as a vehicle comprising the control device are also described.

Control device and method for controlling an exhaust gas aftertreatment system

The present invention relates to use of a lubrication oil that forms water-soluble ash when combusted in an engine system, where the engine system comprises an internal combustion engine; an exhaust gas system comprising a diesel particulate filter to capture particulate matter from the exhaust gases, including the water-soluble ash; and an exhaust gas conduit to lead exhaust gases from the internal combustion engine to the exhaust gas system, and to collect condensed water formed by a cold start and/or a cold operation of the internal combustion engine and lead the condensed water through the diesel particulate filter, thereby dissolving and removing the water-soluble ash from the diesel particulate filter.
