摘要： PROBLEM TO BE SOLVED: To avoid the problem of being damaged when a temperature gradient becomes large at regenerating time when an exhaust particulate accumulates much in a central part of a honeycomb type monolithic filter 1. SOLUTION: This exhaust particulate filter is constituted as the honeycomb type monolithic filter 1 using porous ceramics, and a blocking-up cell 2A having the upstream end blocked up by a mesh-clogging part 4 and an opening cell 2B having the downstream end blocked up by a mesh-clogging part 5 are alternately adjacently arranged. The length L of the downstream side mesh-clogging part 5 of the opening cell 2B is longest in the filter center, and is shortest in the outermost peripheral part of the filter, and gradually changes between both. The substantial passage length of the opening cell 2B is determined according to this length. Thus, since ventilation resistance of the filter central part becomes large and exhaust air flowing in an outer peripheral part increases, the distribution of a particulate accumulation quantity is further uniformized, and the temperature gradient at regenerating time is reduced.

摘要： PROBLEM TO BE SOLVED: To improve a collecting efficiency of an exhaust fine particle immediately after shopping or immediately after exchanging of the exhaust fine particle. SOLUTION: The fine exhaust filter is provided with a filter body 1 of a honeycomb monolithic structure using porous ceramics. The exhaust fine particle is collected when it passes through a wall between a cell with a chocked upstream end and a cell with a chocked downstream end. An inflammable sheet 2 such as a sheet of air-permeable paper is previously pasted to a front end face of a filter body 1. Immediately after operation starting, the inflammable sheet 2 burns, a fine particle such as a soot generated at that time is attached to the filter body 1 to improve the initial collecting efficiency. Soon the inflammable sheet 2 burns completely due to exhaust heat of operation, and thereafter has no detrimental effect on pressure loss. COPYRIGHT: (C)2004,JPO
