摘要： PROBLEM TO BE SOLVED: To provide a gas reformer and an exhaust gas purification system which have an arrangement structure of dielectrics contributing to high exhaust gas purification performance even at a low temperature.SOLUTION: In a gas reformer 1d, spherical dielectrics 5 each consisting of a dielectric having a relatively high dielectric constant, cylindrical parts 3 each consisting of a dielectric having a relatively low dielectric constant, and plate-shaped dielectrics 4 are provided between a pair of electrodes 60, 61 so that they are layered respectively in two or more layers. Gas flow regions 7 allowing gas flow are formed in the shape of a layer between them. By such a configuration, when a voltage is applied between the electrodes 60, 61, a discharge region is effectively expanded between two dielectric parts to achieve a high gas reforming function by wide area plasma, which contributes to high exhaust gas purification performance.

摘要： An exhaust emission control apparatus that is used with an internal combustion engine to use both a NOx retention member and a catalyst while avoiding a decrease in the exhaust gas purification capacity. A NOx occlusion reduction type catalyst is placed in an exhaust path of an internal combustion engine. The NOx occlusion reduction type catalyst includes a base material. The base material includes an exhaust inflow cell, which is closed at its downstream side; and an exhaust outflow cell, which is closed at its upstream side and is adjacent to the first cell with the partition wall positioned in between. The exhaust inflow cell is configured so that a NOx retention layer is formed on the inner surface thereof, and the exhaust outflow cell is configured so that a catalyst layer is formed on the inner surface thereof, respectively.

摘要： PROBLEM TO BE SOLVED: To prevent drop of NOx conversion performance even if the temperature of a NOx storage catalyst is low in engine start in a hybrid vehicle. SOLUTION: An exhaust emission control system for a hybrid vehicle has the NOx storage catalyst provided in an exhaust gas passage of an internal combustion engine. An ozone former is provided upstream of the NOx storage catalyst and supplies ozone (O 3 ) to the upstream side of the NOx storage catalyst of the exhaust gas passage. Since the internal combustion engine stops during motor travel in which an electric motor is used for propelling force in the hybrid vehicle, the catalyst bed temperature of the NOx storage catalyst provided in the exhaust gas passage of the internal combustion engine drops and NO storage capacity drops in that period. Ozone, therefore, is supplied to the exhaust gas passage concurrently with or before start of the internal combustion engine. Ozone oxidizes NO in exhaust gas and converts the same to NO 2 . Since the NOx storage catalyst can convert NO 2 even if the catalyst bed temperature is low, NOx conversion performance can be maintained. COPYRIGHT: (C)2008,JPO&INPIT
摘要翻译：要解决的问题：即使在混合动力车辆中的发动机起动中，NOx储存催化剂的温度低，也可防止NOx转化性能下降。解决方案：用于混合动力车辆的废气排放控制系统具有设置在内燃机的排气通道中的NOx储存催化剂。在NOx吸留催化剂的上游设置有臭氧形成剂，并向臭氧通道的NOx吸留催化剂的上游侧供给臭氧（O 3 ）。由于在电动机行驶中使内燃机在混合动力车辆中用于推进力的情况下停止内燃机，所以设置在内燃机的排气通路内的NOx吸留催化剂的催化剂床温度下降，NO存储容量下降在那个时期。因此，在内燃机起动之前或之后，将臭氧供给至废气通道。臭氧氧化废气中的NO，并将其转化为NO 2 。由于即使催化剂床温度低，NOx吸留催化剂也能够转化NO 2 ，因此可以维持NOx转化性能。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an exhaust gas purifier for an internal combustion engine exhibiting the function of a catalyst without lowering the function of ozone, even when oxidizing and removing PM with ozone. SOLUTION: The exhaust gas purifier for an internal combustion engine is a wall flow-type particulate filter (30) collecting particulate matter contained in an exhaust gas in an exhaust passage. A catalyst (38) is carried only on the downstream side of the exhaust gas in a partition wall (37) of the particulate filter. Thus, when supplying ozone, ozone is introduced into the upstream side of the partition wall (37) on which PM is collected, and ozone does not come into contact with the catalyst carried only on the downstream side of the exhaust gas in the partition wall, whereby the decomposition of ozone is prevented to exhibit a PM oxidation function.
