子処理装置。[Claim for Utility Model Registration] The exhaust passage of the engine is branched to form two branch exhaust passages, and one branch exhaust passage has a porous structure made of a pumice-like porous member that has an internal communication part that becomes a fluid passage. The type trap is divided into two types, and a lattice type trap having a plurality of fluid passages separated from each other by a honeycomb-like porous member and substantially parallel to the exhaust flow is interposed in the other branched exhaust passage, and an exhaust temperature detection means for detecting exhaust gas temperature or an engine operating state related thereto; an engine load detection means for detecting an engine load; Exhaust particles of an internal combustion engine, characterized in that the exhaust particulates of an internal combustion engine are provided with a valve device that opens and closes the branch exhaust passage so that the exhaust gas flows through the grid-type trap, and at other times, the exhaust gas flows through the porous trap. Processing equipment.
