摘要： A catalyst deterioration detecting apparatus aims at accurately determining whether or not a catalyst deteriorates even if a strict standard for catalyst deterioration is established. The catalyst deterioration detecting apparatus includes catalyst temperature sensing means for obtaining temperature of a catalyst, including ceria (CeO2) serving as an oxygen storage agent, and deterioration detecting means for detecting a degree of deterioration of the catalyst if the temperature is obtained by the catalyst temperature sensing means is equal to or higher than an activation temperature at which the catalyst is activated and is in a particular temperature range causing NOX conversion efficiency of the catalyst to decrease.

摘要： When a NOx-releasing unit is operated to change an air-fuel ratio to a rich side to thereby establish a low-oxygen-concentration atmosphere of an exhaust gas such that NOx is released from a NOx catalyst, a reducer-supplying unit additionally supplies a reducer during an operating period of the NOx-releasing unit for reducing NOx released into an exhaust path such that release of NOx balances with reduction of NOx, thereby reducing NOx released from the NOx catalyst and thus suppressing worsening of an exhaust gas performance.

摘要： An exhaust emission purifier includes a catalyst unit disposed in an exhaust pipe of an engine. Electrodes (reaction adjustment unit) are provided on a honeycomb carrier of the catalyst unit in a layered form in order to apply an electric field to the vicinity of the catalyst surface to thereby adjust the catalytic reaction. An ECU serves as a status detection unit to detect factors which affect the exhaust gas purifying performance of the catalyst unit (i.e., operating conditions), and serves as a control unit which controls the electric field applied by the electrodes, on the basis of the detected operating conditions.

摘要： The present plasma type exhaust gas cleaning apparatus comprises a dielectric (5) arranged between a discharge electrode (7) and a ground electrode (8). The dielectric has a plurality of independent cavities (6) formed therein. The exhaust gas from combustion equipment (1) flows through the interiors of the plurality of independent cavities (6). Thus, in the plasma type exhaust gas cleaning apparatus, the discharge electrode (7) and the ground electrode (8) are securely partitioned by the cavities (6). When a voltage from a high voltage generator (9) is applied to between the discharge electrode (7) and the ground electrode (8), plasma resulting from corona discharges occurs in each individual cavity (6) without arising directly across the discharge electrode (7) and the ground electrode (8). The exhaust gas is thereby cleaned up.

摘要： 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.

摘要： In an exhaust gas purifying catalyst, an acid material with a high affinity with respect to an absorbing agent is dispersed and mixed in a catalyst layer, to which the absorbing agent is added, or a layer of the acid material is formed inside the catalyst layer in order to prevent the absorbing agent from moving from the catalyst layer into the carrier. This reduces the permeation of the absorbing agent added to the catalyst layer into a carrier, the evaporation and splash of the absorbing agent from the catalyst, and the deterioration in the durability and the exhaust gas purifying performance of the catalyst.
