摘要： The present disclosure relates to mixing devices included in automotive exhaust treatment systems. More particularly, the present disclosure relates to reducing agent mixers for mixing reducing agents with exhaust streams to induce a chemical reaction between the reducing agent and exhaust gasses to reduce Nitrous Oxides (NOx) in the exhaust gas. Reducing agent mixers in accordance with the present disclosure include reducing agent delivery devices for conducting reducing agents into an internal mixing space through which exhaust gasses flow.

摘要： The purpose of the present invention is to provide an exhaust purifier which suppresses unnecessary consumption of pressurization air so as to improve a removal rate of dust. An exhaust purifier for removing particulate matter adhered to a NOx catalyst by injecting pressurized air using an air injection nozzle into a housing of a catalyst reactor in which the NOx catalyst serving as a catalyst is positioned, wherein an injection valve of a soot blower supplying pressurized air into the housing of the catalyst reactor is opened and closed based on an exhaust gas flow rate so as to inject the pressurized air.

摘要： The invention relates to: a catalytic composition that is active in the selective catalytic reduction of nitric oxides, containing an iron-containing MFI-type zeolite and an iron-containing BEA-type zeolite, wherein the weight average particle size d50 of the MFI-type zeolite and the BEA-type zeolite is different; a method for producing an SCR catalyst; and the SCR catalyst produced in this way. The adhesion of the coating is improved in that the weight average particle sizes of the MFI-type and BEA-type zeolites are different.
