摘要：
To equip a diesel particle filter with a zeolite-containing coating uniformly over the entire length of the particle filter and with a further zeolite-free coating which is applied, from the entry side of the filter, solely up to a specific length of the filter, it is proposed, first, to apply the zeolite-free coating from the entry side of the filter and only thereafter to apply the zeolite-containing coating over the entire length of the filter from the exit side of the filter. As a result of this sequence of coatings, a better adhesive strength of the coatings than when both coatings are applied from the entry side is ensured.
