摘要： In an exhaust gas purifying apparatus provided with a lean NOx catalyst supporting a catalyst layer, which contains a NOx trapping component, on a honeycomb substrate formed so as not to cause an alkali attack, the invention prevents trapped NOx from being dissociated and exhausted during the time of a rich spike. A NOx reducing catalyst with the function of reducing NOx by a reductant in a rich or stoichiometric condition, e.g., a three-way catalyst, is disposed downstream of the lean NOx catalyst. In the case of increasing the amount of the NOx trapping component in the lean NOx catalyst to enhance a NOx trapping capability, even if a part of trapped NOx is dissociated during the time of the rich spike, the dissociated NOx can be reduced by the NOx reducing catalyst disposed on the downstream side.

摘要： An exhaust gas purification filter for a diesel internal combustion engine. In this filter, catalyst layers are not formed at portions to which a sealant of the filter is stuck so that a substrate of the honeycomb structure is exposed, but formed at portions to which a substrate of the honeycomb structure is exposed. If the sealant is stuck to catalyst layer portions, because the catalyst layers are brittle and the surfaces thereof have asperities, the fixing strength of the sealant is reduced, so that the sealing portions becomes prone to falling-off under shocks or the like. By exposing the substrate of the honeycomb structure and sticking the sealant to the exposed portions, it is possible to enhance the fixing strength of the sealant and thereby to prevent the sealing portions from falling off.
摘要翻译： 一种用于柴油内燃机的废气净化过滤器。 在该过滤器中，催化剂层不形成在过滤器的密封剂被粘合的部分处，使得蜂窝结构体的基材露出，但形成在蜂窝结构体的基材暴露的部分。 如果密封剂粘附到催化剂层部分，由于催化剂层脆性并且其表面具有凹凸，所以密封剂的固定强度降低，使得密封部分在冲击等下容易脱落。 通过使蜂窝结构体的基材露出并将密封剂粘贴到露出部分，可以提高密封剂的固定强度，从而防止密封部分脱落。

摘要： An apparatus and method of highly efficiently purifying nitrogen oxides are provided. An NOx chemisorption reduction catalyst chemically absorbs NOx under a condition that an exhaust gas of an internal combustion engine is an oxidizing atmosphere and deoxidizes adsorbed NOx under a reducing atmosphere. An SOx absorbent absorbs SOx contained in the exhaust gas of the oxidizing atmosphere, and deoxidizes and release SOx absorbed in the reducing atmospheric exhaust gas. The catalyst and absorbent are arranged in the exhaust path to purify the exhaust gas while preventing or suppressing SOx-poisoning of the NOx chemisorption reduction catalyst.
