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.

Method and device for a particle filter for an exhaust system for a combustion engine, wherein the filter is regenerated by spontaneous combustion of particles accumulated in the filter. Exhaust gases from the combustion engine are led, during operation, past the filter when the counterpressure in the exhaust gases which is caused by the filter exceeds a certain level. The invention also relates to a silencer in a vehicle which is driven by the combustion engine.
