The exhaust gas purification device includes an HC trapping converter comprising a carrier; an HC adsorbing layer, supported on the carrier and adapted to adsorb unburned fuel; and a ternary catalyst layer, supported on a surface of the HC adsorbing layer and adapted to oxidize and remove the unburned fuel. The HC adsorbing layer includes particulate HC adsorbents each of which has a follow space and which are stacked. The ternary catalyst layer covers the HC absorbing layer such that a thickness of the ternary catalyst layer increases from an upstream side to a downstream side of the converter in the direction of exhaust gas flow.

Abstract: A degradation estimating apparatus for an unburned fuel component adsorption catalyst, which is connected with an internal combustion engine and has an unburned fuel component adsorbent and an oxygen storage component is provided. The apparatus includes a degradation estimating unit for making estimation for a degradation of the unburned fuel component adsorption catalyst on the basis of a first term and a second term. The first term is from the cancellation of the fuel supply to detecting a variation of an upstream side air-fuel ratio occurring due to the increase of the reductant quantity in the exhaust gas. The second term is from the cancellation of the fuel supply to detecting of a variation of the downstream side air-fuel ratio due to an increase of the reductant quantity.

Abstract: The invention relates to an HC trap catalyst and a preparation method for the HC trap catalyst. The HC trap catalyst includes an HC adsorbent for adsorbing HC in exhaust gas exhausted from an internal combustion engine, and an oxidation accelerating element contained in the HC adsorbent for accelerating partial oxidation of the HC adsorbed by the HC adsorbent. With the above configuration, HC in exhaust gas can be partially oxidized. As a result, the oxidation reactivity of HC can be improved remarkably. Further, since the oxidation accelerating element is contained in the HC adsorbent, the HC adsorbed in the HC adsorbent can be partially oxidized directly. As a result, the partial oxidation can be promoted efficiently.

Abstract: The present invention provides an exhaust gas purifying catalyst that is capable of substantially reducing the degree of deterioration in an exhaust gas purifying capability, which results from dissipation of an absorbent agent. Accordingly, an exhaust gas purifying catalyst, which includes a carrier and a catalyst layer, and to which at least one material selected from a group of alkali metals and alkali earth metals is added as an absorbent agent, is characterized in that acid material with a high affinity with respect to the absorbent agent is mixed in the catalyst layer so as to fix the absorbent agent, and an inhibiting layer is formed between the catalyst layer and the carrier so as to inhibit the movement of the absorbent agent toward the carrier.

The catalytic layer consists of a first catalytic layer (20) which contains the occluding agent (potassium and/or the like) and an acid material (30) having a high affinity to the occluding agent, and a second catalytic layer (40) which contains the occluding agent and does not contain the acid material.

Abstract: It is an object of the present invention to provide an exhaust gas purifying catalyst formed as a single catalyst that has a great deal of flexibility when being assembled into an exhaust system and that is capable of executing both an NOx absorbing function and a three-way function in a desired manner. To attain the this object, an absorbent catalyst layer to which an absorbent agent such as potassium and an acid material such as zeolite are added, an absorbent agent block layer formed of zeolite, and a three-way catalyst layer to which an acid material such as phosphorus is added are bonded together on a cordierite carrier. The acid material in the absorbent catalyst layer and the absorbent agent block layer inhibit the movement of the absorbent agent to the three-way catalyst layer, and transform the absorbent agent into harmless and stable potassium phosphate even if the absorbent agent reaches the three-way catalyst.
