摘要： PROBLEM TO BE SOLVED: To improve the utilization factor of ozone by preventing the leak of the ozone. SOLUTION: An exhaust emission controller (12) is arranged in an exhaust passage in which exhaust gas from an internal combustion engine is distributed, for trapping the particulate materials in the exhaust gas. Active oxygen is supplied to the exhaust emission controller by an active oxygen supply means (16). Downstream of the exhaust emission controller (12), an active oxygen treatment part is provided which has active oxygen adsorbents (22a, 22b) for trapping the active oxygen in the exhaust gas passing through the exhaust emission controller or desorbing the trapped active oxygen. The active oxygen adsorbents (22a, 22b) are controlled into an adsorbing condition to trap the active oxygen or into a desorbing condition to desorb the active oxygen by an adsorbent control means (ECU 60). The active oxygen desorbed from the active oxygen adsorbents is resupplied via circulation passages (26a, 26b, 30a) to the exhaust emission controller (12). COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To obtain superior particulate matter oxidation efficiency even at low temperatures while suppressing a consumption amount of active oxygen in an exhaust emission control device of an internal combustion engine. SOLUTION: This exhaust emission control device of the internal combustion engine includes a filter for capturing particulate matter, an active oxygen decomposition catalyst for decomposing active oxygen and generating an oxygen radical, an active oxygen supply device for supplying active oxygen to the active oxygen decomposition catalyst when oxidizing the particulate matter using the oxygen radical, and an oxidizing portion control means that controls a portion in a filter where the particulate matter is oxidized by adjusting the flow rate of gas flowing from the active oxygen decomposition catalyst to the filter. When the gas flow rate is comparatively high, particulate matter accumulated on a portion far in distance from the active oxygen decomposition catalyst is oxidized. When the gas flow rate is comparatively low, particulate matter accumulated on a portion close in distance from the active oxygen decomposition catalyst is oxidized. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device for an internal combustion engine capable of efficiently controlling the emission of carbon monoxide included in exhaust gas by using active oxygen, while restricting power consumption over the whole of a system. SOLUTION: The internal combustion engine 10 comprises: an Ag catalyst 16 including at least Ag as a catalyst component; an ozone generator 18 for supplying ozone to the Ag catalyst 16; and a CO sensor 22 for detecting concentration of CO included in exhaust gas. When the CO sensor 22 detects CO, an ECU 30 supplies ozone to the Ag catalyst 16 by using the ozone generator 18, and in other cases, stops supply of ozone. With this structure, when CO is included in exhaust gas, CO can be efficiently eliminated by the Ag catalyst 16 and ozone. When CO is not included in exhaust gas, excessive supply of ozone can be prevented, and power consumption of the system can be saved. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To surely prevent deactivation of catalyst caused by hydrocarbon (HC) poisoning, as well as to reduce an influence on fuel consumption, regarding an exhaust gas purifier for internal combustion engine. SOLUTION: The exhaust gas purifier includes a catalyst for exhaust emission purification, and a NOx sensor for detecting NOx concentrations of exhaust gas flowing out of the catalyst. An internal combustion engine switches between a lean operation to make exhaust air-fuel ratio larger than theoretical air-fuel ratio and a rich operation to make the exhaust air-fuel ratio equal to or smaller than the theoretical air-fuel ratio. ECU performs deactivation determination of catalysts based on values of the NOx sensor during the rich operation. If it is determined that a catalyst has been deactivated, the HC poisoning is resolved by supplying active oxygen to the catalyst. The supply of the active oxygen is performed during the lean operation. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission controller for an internal combustion engine capable of reliably reducing CO in exhaust gas, and improving exhaust gas emission even in a low-temperature state such as cold starting. SOLUTION: A prestage catalyst 16, a CO absorbent 18, and an Ag catalyst 20 are successively arranged in an exhaust gas passage 14 from the upstream side to the downstream side in the exhaust gas flowing direction. Furthermore, an ozone generator 22 for supplying ozone to the Ag catalyst 20 is provided. In the low-temperature range of some extent, CO in the exhaust gas is purified with the Ag catalyst 20 and ozone. Furthermore, in an extremely low-temperature range in which a CO purification ratio is lowered even if ozone is used, CO in the exhaust gas is adsorbed by the CO adsorbent 18. The adsorbed CO is desorbed from the adsorbent 18 when the temperature of the adsorbent 18 is slightly raised, and purified with the Ag catalyst 20 and ozone. Thus, CO in the exhaust gas can be reduced in an extensive temperature range including an extreme low-temperature range. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To use a catalyst and an active oxygen supply device in a proper layout to a main catalyst which exhibits a high performance due to the presence of active oxygen. SOLUTION: An Ag catalyst 32 is installed in the exhaust passage 14 of an internal combustion engine 10. A ternary catalyst 34 is installed on the downstream side of the Ag catalyst 32, and an ozone generator 36 is installed on the upstream side of the Ag catalyst 32. During the cold starting, ozone is supplied to the Ag catalyst 32, and CO in the exhaust gas is removed due to the reaction between Ag and ozone in low temperature conditions. Also, the ternary catalyst 34 on the downstream side is prematurely activated by the heat of reaction between Ag and ozone. Since the exhaust emission control device can exhibit high purification performance even at low temperatures, the exhaust emission of the engine during the starting can be improved. The ternary catalyst 34 on the downstream side can be protected against ozone by consuming ozone by the Ag catalyst 32 on the upstream side. COPYRIGHT: (C)2010,JPO&INPIT
