Abstract
A process for the ignition of a regenerative soot filter adapted to be ignited in which the temperature, respectively, heat quantity necessary for the ignition of the filter is produced by charging a storage container located ahead of the soot filter or in connection with the soot filter which contains a hydride-forming alloy or a hydride-forming material. The necessary hydrogen is taken from a second storage container with a different alloy storing hydrogen, which is brought to a temperature by the exhaust gases so that a sufficient hydrogen pressure results therefrom. After the ignition, the second storage container is cooled off and the hydrogen is again conducted from the first storage container heated by the exhaust gases back into the second storage container so that the ignition operation can be repeated with renewed heating of the second storage container.
