Abstract: The invention relates to a method for attenuating vibrations and/or shocks, said method comprising providing a damper assembly which comprises a moving part and a supramolecular polymer in contact with said moving part, and exposing said moving part to said vibrations and/or shocks, wherein said supramolecular polymer is obtained by reacting: at least one first polymer [polymer (P1)] comprising a polymer chain [chain (R)] consisting of a plurality of non-ionisable recurring units [units (U)], said polymer (P1) having two chain ends (E1, E1?), each end comprising at least one ionisable acid group, and at least one second polymer [polymer (P2)] comprising a polymer chain [chain (R)] consisting of a plurality of recurring units [units (U)], said chain (R) being equal to or different from that of polymer (P1), and said polymer (P2) having two chain ends (E2, E2?), each end comprising at least one ionisable amino group.

Abstract: A method for regenerating a particulate filter of an internal-combustion engine, provides for air to be supplied into the exhaust gas pipe upstream of the particulate filter in order to perform post-combustion in the exhaust gas pipe. The method provides for fuel to be supplied to the cylinders of the internal-combustion engine by means of a high-pressure pumping unit, and for fuel to be supplied into the exhaust pipe upstream of the particulate filter by means of the high-pressure pumping unit.
