    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 order to suppress deposition of constituent of a reducing agent (dissolved matter) in an exhaust passage of an engine enhancing an elimination rate of NOx even when temperature of an exhaust emission from the engine is low, an exhaust emission purifying apparatus is provided with an electro-generative-heat carrier provided on an upstream side of an injection nozzle that supplies the reducing agent into the exhaust emission on upstream side of a reduction catalyst in an exhaust pipe, the exhaust emission being heated to a temperature equal to or higher than a melting point of the dissolved matter whereby deposition of the dissolved matter on an inner wall surface of the exhaust pipe is suppressed to effectively use the supplied reducing agent for catalytic reduction reaction, even when the exhaust emission temperature is lower than the melting point of the dissolved matter of the reducing agent.

    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.
