| 20120122663 | PROCESS FOR PRODUCING CATALYST FOR EXHAUST GAS PURIFICATION AND CATALYST FOR EXHAUST GAS PURIFICATION - An object of the present invention is to provide a process for producing a catalyst for exhaust gas purification capable of increasing the area brought into contact with exhaust gas to improve the exhaust gas purification efficiency without decrease in strength of the catalyst for exhaust gas purification and without significant increase in manufacturing cost of the catalyst for exhaust gas purification. The present invention provides a process for producing a catalyst for exhaust gas purification formed by forming a coating layer containing a catalyst component on a honeycomb support, characterized in that the method comprises immersing the honeycomb support in a thixotropic slurry containing the catalyst component or sucking the slurry into the honeycomb support, removing the honeycomb support from the slurry, spraying pulsed air onto an end surface of the removed honeycomb support in the axial direction thereof, and baking the honeycomb support to form the coating layer on the honeycomb support. | 05-17-2012 |

| 20090241780 | MAINTENANCE METHOD FOR PARTICULATE FILTER - Provided is a method for performing maintenance of a particulate which can reliably remove combustion residue by means of backwash air without use of hot water and the like while cutting equipment expenses, so that substantial increase in exhaust pressure and deterioration of fuel economy during operation can be prevented. | 10-01-2009 |
| 20090165447 | EXHAUST PURIFICATION DEVICE FOR ENGINE - An agitating device for agitating the exhaust gas of an engine includes a base plate having a plurality of through holes that are defined by radially extending spoke portions and a ring-like rim portion and are arranged in a circular pattern in a circumferential direction of the base plate, and a plurality of fins expanding from the respective spokes on a slant with respect to the base plate. The base plate is fixed in the exhaust passage by the rim portion being jointed to the exhaust passage at welded portions. The welded portions are each disposed in an area between respective two adjacent spoke portions in the circumferential direction of the base plate, and an outer edge of the rim portion positioned on the outer side of the rim portion in extending directions of the spoke portions is located next to the exhaust passage with a gap provided therebetween. | 07-02-2009 |
