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 comprising 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) bringing 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: Provided is an electric battery junction arrangement for connecting an electric battery arrangement to one or more electrical loads. The electric battery arrangement comprising two or more electric battery cells and a control circuit comprising: (i) a first control circuit branch connectable to a positive side of the battery arrangement and a positive side of an electrical load; (ii) a second control circuit branch connectable to a negative side of the battery arrangement and a negative side of an electrical load; (iii) at least one semiconductor apparatus provided between and configured to control electric current between the battery arrangement and the loads; and (iv) a switching apparatus comprising at least one mechanical switch arranged in an electrical circuit connection between the first and the second control circuit branch for electrically connecting and disconnecting the first and the second control circuit branch to and from each other.

Abstract: Provided are an exhaust gas treatment system and method for regenerating the exhaust gas treatment system. The exhaust gas treatment system comprises: an oxidation catalyst assembly; a particulate filter downstream of the oxidation catalyst assembly; a reducing agent dosing device downstream of the particulate filter; and a selective catalytic reduction device downstream of the reducing agent dosing device. The oxidation catalyst assembly comprises a first oxidation catalyst to selectively oxidize hydrocarbons in the exhaust stream, at least partially, with substantially no concomitant oxidation of sulfur oxides in the exhaust stream; and a second oxidation catalyst downstream of the first oxidation catalyst, to oxidize hydrocarbons or partially oxidized hydrocarbons having slipped through the first oxidation catalyst, as well as to concomitantly oxidize NO to NO2. The system can be regenerated when running on high-sulfur fuels to regenerate the particulate filter as well as remove sulfur species deposited on the system catalysts.
