摘要： PURPOSE:To effectively remove the NOx in the exhaust gas over the entire range of the actual exhaust gas temp. from an automobile by controlling the surface temp. of an exhaust gas purifying material in the optimum temp. range to NOx removal and adding hydrocarbons or oxygen-contg. org. compds. into the exhaust gas on the upstream side of the purifying material. CONSTITUTION:An exhaust gas purifying material 3 is set midway in an exhaust gas duct 2, and a reducing agent such as hydrocarbons and oxygen-contg. org. compds. is added to the exhaust gas on the upstream side of the material 3 by an adding device 4. The surface temp. of the material 3 measured by a temp. measuring device 6 is controlled in the optimum temp. range to NOx by a temp. control means. The optimum temp. is controlled within about + or -100 deg.C, preferably about + or -50 deg.C, of the temp. exhibiting the maximum NOx removing rate by the material 3. The temp. control means consists of a double- structure exhaust gas duct 7 and a refrigerant circulating device 8, and the refrigerant is filled in the outer layer of the duct 7.

摘要： PURPOSE:To clean an exhaust gas of high oxygen concentration containing particulates, HC, and NOx by arranging the first cleaning member of a porous ceramic body carrying a catalyst component at the inlet side of the exhaust gas and a heat resistant porous filter, a porous ceramic layer on which a catalyst component added with a rare earth metal is carried at the outlet side of the exhaust gas. CONSTITUTION:The first cleaning member, which carries an element selected from alkaline metal elements and Cu, Co, etc., is installed on a porous ceramic substrate which is placed at the inlet side of exhaust gas. A porous ceramic layer carrying a material, which comprises a similar catalyst component as that on the first cleaning member and a rare earth element added, is installed on a heat resistant porous ceramic filter to form the second cleaning member which is placed at the outlet side. The amount of the first catalyst is 0.05-6.0wt.% of the substrate, and the amount of the second catalyst is 6.0wt.% or more of the porous ceramic layer. NOx in the exhaust gas is removed in the presence of HC as a reductant at the inlet side, while particulates, HC, and CO are removed at the outlet side.

摘要： PURPOSE:To effectively decrease NOx in exhaust gas at a relatively low temp. as /g specific surface area is formed on the surface of a porous ceramic filter having 20-90 porosity to obtain a purying material for exhaust gas. This purifying member is installed in the middle of an exhaust gas flue. A liquid hydrocarbon is added to the exhaust gas in the upstream side of the purifying member. By maintaining temp. of the exhaust gas passing through the purifying member to 200-500 deg.C, nitrogen oxides in the exhaust gas are reducd and removed by using a liquid hydrocarbon as a reducing agent.

摘要： PURPOSE:To reduce thermal energy for incineration of particulate by providing a first filter and a second filter into which exhaust gas is let flow selectively on the way of exhaust passages, and arranging both the filters to be close to each other. CONSTITUTION:A first and second filters 1, 2 respectively having electric heaters 11, 12 for incinerating particulate caught in filters are provided on the way of exhaust passages 6a, 6b. By operating valves 7a, 7b in the respective exhaust passages 6a, 6b exhaust gas is selectively let flow in either the first filter 1 or the second filter 2. The first filter 1 and the second filter 2 are arranged to be close to each other. Thermal energy of exhaust gas passing through the filter on the gas flow side is transmitted to the filter on the gas interception side. Thus, thermal energy for incineration of particulate can be reduced.
