    摘要: PROBLEM TO BE SOLVED: To provide a heat accumulation element efficiently accumulating heat of exhaust gas and effectively using the heat and having superior durability.
    SOLUTION: A body 1a of the heat accumulation element 1 has a honeycomb structure, and fluid passages 11 where fluid circulates and heat-accumulating medium portions 12 (formed by plugging both honeycomb end faces) where a medium for storing heat is enclosed are formed. Specifically, the heat accumulation element 1 has partition walls 4, and one opening portion and the other opening portion of each of predetermined cells 3 of the honeycomb structure, having the large number of cells 3 partitioned and formed to function as fluid passages are plugged and fired to form plugged cells 3a. A heat-accumulating medium 9 is provided in the plugged cells 3a; open cells 3b which are not plugged and fired serve as the fluid passages 11; the plugged cells 3a plugged and fired serve as the heat-accumulating medium portions 12; and heat exchange is performed between the fluid made to flow within the open cells 3b and the heat-accumulating medium 9 within the plugged cells 3a.

    摘要: PROBLEM TO BE SOLVED: To provide an exhaust treatment device for a diesel engine, capable of increasing the concentration of PM in EGR gas. SOLUTION: An exhaust gas flow divider 2 includes electrodes 12 and 13 having different polarities, PM in exhaust gas 3 is charged with a predetermined polarity by corona discharge between the electrodes 12 and 13, and an exhaust gas swirl chamber peripheral wall 14 surrounding an exhaust gas swirl chamber 9 is constituted by the electrode 13 having polarity reverse to the charged PM. The charged PM in the exhaust gas 3 swirling within the swirl chamber 9 is caused to be localized near the exhaust gas swirl chamber peripheral wall 14 by centrifugal force and electrostatic force to cause exhaust gas 3 containing the localized PM to be diverted, as EGR gas 4, into an exhaust gas swirl chamber terminal part 7, while causing exhaust gas 3 near a center tube 7 to be diverted, as discharge gas 5, into the center tube 7 from a release gas inlet hole 8 and a gas vent hole 24.
