Exhaust gas purifying filter

摘要

The present invention provides an exhaust gas purifying filter of which the plugs can be used as part of filter. The exhaust gas purifying filter of the present invention has a honeycomb structure comprising a multitude of cells 10 each surrounded by walls 11, each of the cells being stopped with a plug 2 on one end thereof. The walls 11 and the plugs 2 are all made of a porous material and value of M = (L/t) x (P1/P2) is in a range of 10 < M < 90, where P1 is the porosity of said walls 11, P2 is the porosity of said plugs 2, t is mean thickness of said walls 11 and L is mean length of said plugs 2.
