摘要： In an exhaust gas purification apparatus for an engine includes a bubble generation device, the bubble generation device for mixing nano-sized to micro-sized bubbles into a liquid reducing agent or a precursor thereof injection-supplied from an injection nozzle is disposed in a reducing agent supply system running from a reducing agent tank to the injection nozzle. When the liquid reducing agent or the precursor thereof is injection-supplied from the injection nozzle, the liquid reducing agent or the precursor thereof is divided by bubbles, and the bubbles are radically inflated and burst by a pressure change and a temperature change at the time of injection-supplying, so that microparticulation of the liquid reducing agent or the precursor thereof is facilitated.

摘要： In an exhaust filter, a urea hydrolysis catalyst is supported on a first portion of an inner wall of a cell passage on the inlet side, and a first NOx reducing catalyst is supported on a second portion of the inner wall of the inlet-side passage downstream of the first portion. A second NOx reducing catalyst is supported on a third portion of an inner wall of a cell passage on the outlet side where the third portion overlaps with the first portion in a direction of intersection with the exhaust flow into the exhaust filter or is downstream of the first portion. An oxidation catalyst is supported on a fourth portion of the inner wall of the outlet-side passage downstream of the third portion where the fourth portion overlaps with the second portion in the direction of intersection or is downstream of the second portion.

摘要： An exhaust emission purifying apparatus of the present invention has a casing that includes therein a plurality of layered passages which is formed by partitioning an inside of the casing to thereby allow an exhaust passage from an exhaust emission inlet to an exhaust emission outlet to be folded in its direction once or more, a reduction catalyst that reductively purifies NOx by using a reducing agent, a nozzle that injects the reducing agent or a precursor thereof to an exhaust upstream side of the reduction catalyst, and a filter (DPF) that collects PM suspended in an exhaust emission. The reduction catalyst and the filter are disposed in the different layered passages. Consequently, a more compact exhaust emission purifying apparatus having both NOx removal function and PM collection function can be provided.

摘要： In order to maintain a high NOx purification rate of a NOx reduction catalytic converter even in the case in which an NOx emission amount from an engine changes suddenly, in an exhaust emission purifying apparatus for an engine that reduces and purifies NOx in exhaust gas using ammonia generated from an injection-supplied urea aqueous solution, after engine starting, when an exhaust temperature exceeds a predetermined temperature T (step S1), an amount of urea aqueous solution corresponding to an actual engine operating state is injection-supplied (steps S3 to S5). On the other hand, at a change of the transmission speed ratio based on a driver's shift operation, an engine operating state after the change of the transmission speed ratio is predicted (steps S2, S6), and an amount of urea aqueous solution corresponding to the predicted engine operating state is injection-supplied before the change of the transmission speed ratio is completed (steps S7, S8).
