摘要： PROBLEM TO BE SOLVED: To easily and precisely determine a catalyst deterioration device for determining the deterioration of a catalyst. SOLUTION: This catalyst deterioration determining device 1 determines deterioration of a catalytic converter 2 provided on an exhaust system of an internal combustion engine. The catalyst deterioration determining device 1 has an outlet gas temperature detection means 11 for detecting outlet gas temperature of the catalytic converter 2, a dummy catalyst exhaust gas temperature estimating means 12 for estimating dummy catalyst exhaust gas temperature, and a deterioration determining mean 13 for determining the deterioration of the catalyst based on the outlet gas temperature detected by the outlet gas temperature detection means and the dummy catalyst exhaust gas temperature estimated by the dummy catalyst exhaust gas temperature estimating means. The dummy catalyst exhaust gas temperature is the outlet gas temperature, when the catalytic converter 2 is assumed to be a dummy catalyst which does not actually carry catalyst.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device for an internal combustion engine capable of reducing and purifying a nitrogen oxide with a small added quantity of a reducing agent from a storage reduction catalyst and realizing this without making the device complicated or having adverse effect on the performance of an engine. SOLUTION: In this emission control device provided with the storage reducing catalyst, the nitrogen oxide in exhaust gas stored by the action of the storage reduction catalyst is reduced by adding the reducing agent to purify the exhaust gas, but in adding the reducing agent, the reducing agent is intermittently added synchronizing with the time when exhaust flow becomes minimum in an exhaust stroke. Consequently, since the reducing agent is intermittently added at the time when the exhaust flow is minimum, i.e., the time when the quantity of included oxygen is small, the small added quantity of the reducing agent is sufficient (the rate substantially used for the reducing purification of the nitrogen oxide is increased for the same added quantity), and the nitrogen oxide can be effectively reduced and purified.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device for an internal combustion engine capable of purifying and reproducing a sulfur oxide by discharging the sulfur oxide with a few amount of a reducing agent from an occlusion reducing catalyst poisoned by the sulfur oxide, and capable of realizing purification and regeneration without complicating the device. SOLUTION: The exhaust emission control device 10 is provided with the occlusion reducing catalyst 20, and a reducing agent filling nozzle 22 is arranged in the device. When nitrogen oxides are occluded and reduced by spraying the gasified reducing agent and also the sulfur oxide is discharged from the occlusion reducing catalyst 20 poisoned by the sulfur oxide to be purified and regenerated, the gasified reducing agent is ejected directly to the surface of the occlusion reducing catalyst 20 so that the surface of the occlusion reducing catalyst 20 is covered with the gasified reducing agent and is locally made in a reductive atmosphere. Hereupon, the reducing agent covering the surface is evaporated and burnt, only the surface has locally a high temperature, the sulfur oxide is deoxidized/discharged from the occlusion reducing catalyst 20, purified and regenerated, and the occlusion reducing rate of the nitrogen oxides can be recovered.

摘要： PROBLEM TO BE SOLVED: To allow a computer to aid a designer for effectively designing a real system obtained by composing a plurality of real components and high efficiency without having expert technique. SOLUTION: Each real element tunes the parameter of each virtual element being a virtual model describing its characteristic by a parameter by comparing it with the experiment model of each real element (S3). Successively, a virtual system being the virtual model of the real system optimizes the specification of each virtual element temporarily so as to attain a plurality of targets set in advance together (S5). After that, the specification of each virtual element is optimized finally by comparing it with the experiment model of the real system reflecting the temporarily optimized specification (S7).

摘要： PROBLEM TO BE SOLVED: To inhibit deposit from depositing at an outer part of a reducing gas generating vessel due to temperature drop after completion of heating and decomposition of solid reducer when reducing gas is generated by heating and decomposing the solid reducer held in the reducing gas generating vessel. SOLUTION: When reducing gas is generated by heating and decomposing the solid reducer 14 in the reducing gas generating vessel 12, a temperature adjuster 18 controls a heating state of the solid reducer 14 by a heater 16 to keep pressure in the reducing gas generating vessel 12 higher than saturated vapor pressure of water. Deposit after temperature drop deposits inside of the reducing gas generating vessel 12 where water in liquid phase exists, but does not deposit at the outside of the reducing gas generating vessel 12 where moisture does not exist.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust emission control device that efficiently purifies particulate substance, especially extremely minute PM (particulate matter with a particulate diameter of 50 nm or less). SOLUTION: In the exhaust emission control device 10, an exhaust emission control passage 14, having a flow passage sectional area larger than the pipe passage sectional area of an exhaust pipe of an internal combustion engine, is constructed by a purifying pipe 12, and a cooling members 16 are provided. When exhaust gas from the exhaust pipe flows into the exhaust emission control passage 14, the exhaust gas contacts the cooling member 16 to be cooled. High boiling point hydrocarbon in the exhaust gas is then turned into particles and captured on the wall surface (low temperature surface) of the cooling member 16 by "thermal migration effect", suppressing generation of extremely minute PM caused by condensation of the high boiling point hydrocarbon. Condensation of gaseous volatile substance in the exhaust gas is promoted while forming particles by the cooling of the exhaust gas due to its contact with the cooling member 16, thus preventing generation of PM arising from the sulphate after it has been discharged into the air.
