| 422178000 | And contact regenerating means or means for cleaning an internal surface of the reaction chamber | 8 |
| 20090142239 | Exhaust purification apparatus of internal combustion engine - An exhaust purification apparatus of an internal combustion engine purifying exhaust gas by removing SOx from the exhaust gas is provided. In the exhaust purification apparatus provided with sulfur oxide trapping material for trapping sulfur oxides exhausted from an internal combustion engine, aggregates of the sulfur oxide trapping material ( | 06-04-2009 |
| 20090238731 | SYSTEM AND METHOD FOR ENHANCED REMOVAL OF CO2 FROM A MIXED GAS STREAM - A solvent based flue gas processing system for removing CO | 09-24-2009 |
| 20120058019 | HONEYCOMB FILTER - A honeycomb filter includes a cell having one open end and another closed end that serves as a fluid flow path and a cell having one closed end and another open end, wherein the cells are alternately disposed. The honeycomb filter includes an undeposited region in an upstream region of a partition portion, which has no trapping layer and has a length of 5% or more and 30% or less of the length of the inlet cell. The upstream region of the partition portion includes an undeposited region having an area of 10% or more of that of the cell in a cross-section perpendicular to the exhaust gas flow direction. The undeposited region with no trapping layer in the upstream region decreases the permeation resistance of the partition portion in the upstream region and facilitates fluid passage through the partition portion in the upstream region. | 03-08-2012 |
| 20120058020 | HONEYCOMB FILTER AND METHOD FOR MANUFACTURING HONEYCOMB FILTER - A honeycomb filter includes a plurality of porous partition portions each forming a cell, which is open at one end and closed at the other end and serves as an exhaust gas flow path, and a trapping layer, for trapping and removing solid components contained in the exhaust gas, formed on each of the partition portions. At least part of each of the partition portions is loaded with a catalyst. The amount of catalyst a (g/L) in an upstream partition portion and the amount of catalyst b (g/L) in a downstream partition portion satisfy 1.05≦a/b≦3.00. A method for, limiting a/b to this range includes the entire honeycomb structure, including the partition portions, into contact with a catalyst component to form a catalyst, and subsequently bringing only an upstream region of the honeycomb structure into contact with a catalyst component to form a catalyst. | 03-08-2012 |
| 20120070346 | HONEYCOMB FILTER - A honeycomb filter includes a partition portion having a thickness t | 03-22-2012 |
| 20140030159 | Catalytic Converter, a Kit for Servicing a Catalytic Converter, and Methods for Servicing a Catalytic Converter - A method is disclosed. The method comprises the steps of preparing a serviceable catalytic converter such that a catalyst substrate of the catalytic converter is serviceable while the catalytic converter remains connected to an exhaust system by forming a lower surface of the body of the catalytic converter with an absence of material in order to provide at least one opening in the lower surface of the body of the catalytic converter for permitting selective access to a fluid-flow passage that extends through the body of the catalytic converter that contains the catalyst substrate; and disposing at least one close-out member in the at least one opening for fluidly-sealing the at least one opening. A component of an exhaust system that is serviceable while remaining fluidly-connected and physically-connected to the exhaust system is also disclosed. A kit for servicing a component of an exhaust system that is serviceable while remaining fluidly-connected and physically-connected to the exhaust system is also disclosed. | 01-30-2014 |
| 20150147238 | EXHAUST PURIFICATION SYSTEM OF INTERNAL COMBUSTION ENGINE - In an engine, an exhaust purification catalyst ( | 05-28-2015 |
| 20150292387 | EXHAUST PURIFICATION DEVICE FOR INTERNAL COMBUSTION ENGINE - A particulate filter arranged in an engine exhaust passage is provided with alternately arranged exhaust gas inflow and outflow passages and porous partition walls separating these passages from each other. In each partition wall, a coated zone where a coated layer with an average pore size smaller than that of a partition wall substrate is used to cover the substrate surface and a non-coated zone downstream of the coated zone where the substrate surface is not covered by the coated layer are defined, and the ash in the exhaust gas can pass through the partition wall in the non-coated zone. The quantity of particulate matter trapped at the non-coated zones is calculated, and PM removal control for removing particulate matter from the particulate filter is performed when it is judged that the quantity of trapped particulate matter is greater than an allowable upper limit amount. | 10-15-2015 |
