A method for execution with an exhaust-gas particle filter which is operated with an exhaust-gas aftertreatment system, wherein the exhaust-gas particle filter has a filter wall along which exhaust gas is conducted for filtering purposes; wherein the method includes a regeneration phase with the steps: a) setting a soot load on the exhaust-gas particle filter, wherein the set soot load effects the formation of a soot layer on ash deposited on the filter wall; and b) subsequently mobilising the deposited ash by burning off the formed soot layer during the course of an active regeneration of the exhaust-gas particle filter.

An apparatus for reducing the emission of vaporized hydrocarbons in a fuel supply system. The apparatus comprises a filter for binding the hydrocarbons. A catalyst for oxidation of the hydrocarbons to carbon dioxide and water is provided downstream of the filter.

A catalyst for reducing nitrogen oxides in oxidizing and reducing atmospheres which contains iridium on a support material. Silicon dioxide or a dealuminized zeolite in the acid H form with a modulus of more than 20, preferably more than 100, or mixtures thereof are used as support materials. Iridium is deposited on the external surfaces of these support materials with average particle sizes between 10 and 30 nm. The catalyst is particularly suitable for treating exhaust gases from lean-burn gasoline engines or from diesel engines.
