    Abstract: The invention relates to a particle filter (1) consisting of an envelope (2) and at least one body (3) comprising at least one metallic fibrous layer (4) that is arranged in such a way that a plurality of spatially separated flow paths (5) are formed through the body (3), said flow paths respectively comprising a flow restrictor (6) at at least one point. The inventive particle filter is characterised in that the at least one metallic fibrous layer (4) has a superficial heat capacity of between 400 and 1200 joules per Kelvin and square metre [J/Km2], providing the particle filter with an especially high particle storage capacity and regeneration capacity.

    Abstract: An exhaust system (10) for a lean-burn internal combustion engine comprises a nitrogen oxide (NOX) absorbent (28), a catalyst (30) for catalysing the selective catalytic reduction (SCR) of NOX with a NOX specific reactant, first means (18, 22) for introducing a NOX specific reactant or a precursor thereof into an exhaust gas upstream of the SCR catalyst (30) and means (24) for controlling the introduction of the NOX-specific reactant or precursor thereof into the exhaust gas via the first introducing means (18, 22), wherein the SCR catalyst (30) is disposed upstream of the NOX absorbent (28) and optionally with the NOX absorbent, wherein the control means (24) is arranged to introduce the NOX-specific reactant or the precursor thereof to exhaust gas via the first introducing means (18, 22) only when the SCR catalyst (30) is active, whereby exhaustion of NOX -specific reactant to atmosphere is substantially prevented.
