    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： 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： In an exhaust gas purifying apparatus of an internal combustion engine, the temperature of occlusion-type NOx catalyst is increased to emit SOx when the temperature of occlusion-type NOx catalyst is not less than a set temperature. This prevents the deterioration of fuel consumption and enables the regeneration of a catalyst device by efficiently desorbing a sulfur component from the catalyst device. In this case, the temperature of the occlusion-type NOx catalyst is preferably set according to the frequency of the SOx desorption, and the temperature of the occlusion-type NOx catalyst can be increased by, for example, retarding an ignition timing.

    摘要： An NOx sensor 27 detects the concentration of NOx released from an occlusion type NOx catalyst 25 into the atmosphere. Based on the output of the NOx sensor 27, a total NOx discharge A is computed. When the total NOx discharge A reaches an NOx emission judgment amount A0, corresponding to an NOx emission judgment amount designated by NOx emission regulations, before a distance traveled C reaches a predetermined distance traveled C0, an exhaust air-fuel ratio is changed to a rich air-fuel ratio to release NOx from the occlusion type NOx catalyst 25 efficiently. Then, the exhaust air-fuel ratio is changed to a stoichiometric air-fuel ratio to purify and reduce NOx by a three-way catalyst function.
