20100043406 | EXHAUST EMISSION CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE - An exhaust emission control apparatus that is used with an internal combustion engine to occlude and reduce NOx without blocking the exhaust gas purification function of a catalyst. An NOx occlusion reduction type catalyst and ozone supply device are provided in an exhaust path of the internal combustion engine. The NOx occlusion reduction type catalyst includes a cell into which an exhaust gas flows. An inner surface of the cell is coated with a NOx retention layer and a catalyst layer so that the NOx retention layer and the catalyst layer are provided in the order named from the inner surface of the cell. | 02-25-2010 |
20100132337 | EXHAUST GAS PURIFICATION DEVICE FOR INTERNAL COMBUSTION ENGINE - This invention is intended to ensure that an exhaust gas purification device with an NOx storage reduction catalyst and a particulate filter is able to fully utilize an original NOx storage capability of the NOx storage reduction catalyst. For this end, in addition to the filter | 06-03-2010 |
20100275586 | DEVICE FOR CLEANING EXHAUST GAS OF INTERNAL COMBUSTION ENGINE - The device for cleaning exhaust gas of the internal combustion engine includes means provided in an exhaust gas passage ( | 11-04-2010 |
20100313552 | EXHAUST EMISSION CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE - 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. | 12-16-2010 |
