Abstract: The present disclosure relates to a method of compacting an ash deposited in a particulate filter for a vehicle exhaust gas system, the method includes the steps of: a) providing a low-temperature melting salt to the particulate filter, thereby forming a mixture of the ash and the low-temperature melting salt: and b) heating the particulate filter to a compaction temperature, thereby compacting the mixture of the ash and the low-temperature melting salt. The disclosure further relates to engine oils, dosage products, engine systems and vehicles for implementing such a method.

Abstract: 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.

Abstract: An engine system is provided that uses lubrication oil that forms water-soluble ash when combusted. The engine system comprises an internal combustion engine lubricated by the lubrication oil; an exhaust gas system for cleaning exhaust gases from the internal combustion engine, the exhaust gas system comprising a diesel particulate filter to capture particulate matter from the exhaust gases, wherein the particulate matter comprises the water-soluble ash; an exhaust gas conduit to lead exhaust gases from the internal combustion engine to the exhaust gas system; and condensation means to accumulate condensed water and/or to form an increased amount of condensed water and arranged in fluid connection with the exhaust gas flow upstream of the diesel particulate filter. The exhaust gas conduit is arranged to collect condensed water and lead the condensed water through the diesel particulate filter, thereby dissolving and thus removing the water-soluble ash from the diesel particulate filter.

Abstract: An engine system comprising an internal combustion engine operated by a fuel and lubricated by a lubrication oil comprising at least one additive that renders ash formed by combustion of the lubrication oil ammonia-soluble ash; an exhaust gas system for cleaning an exhaust gas flow from the internal combustion engine , the exhaust gas system comprising a diesel particulate filter to capture particulate matter from the exhaust gases, wherein the particulate matter comprises the ammonia-soluble ash; an exhaust gas conduit to lead exhaust gases from the internal combustion engine through the exhaust gas system; and an injection device to add a solvent comprising ammonia or an ammonia-forming compound into the exhaust gas flow upstream of the diesel particulate filter, wherein the exhaust gas conduit collects the solvent and lead the solvent through the diesel particulate filter, thereby dissolving and thus removing the ammonia-soluble ash from the diesel particulate filter.
