Abstract

A particulate filter provided in this exhaust gas purification device comprises: a whirl-flow section (20) comprising entry-side cells (22) having only an end section on the exhaust gas inlet side open, exit-side cells (24) having only an end section on the exhaust gas outlet side adjacent to the entry-side cells (22) open, and porous partition walls (26) partitioning the entry-side cells (22) and the exit-side cells (24); and a straight-flow section (30) having both an end section on the exhaust gas inlet side and an end section on the exhaust gas outlet side open and comprising through cells (32) that penetrates the filter, along the axial direction thereof. In a cross section orthogonal to the axial direction of the filter (100), the cross-sectional area of the entry-side cells (22) and the exit-side cells (24) included in the outer circumferential area of the cross section is larger than the cross-sectional area of the entry-side cells (22) and the exit-side cells (24) included in the center area of the cross section.

Description

technical field [0001] The present invention relates to an exhaust purification device arranged in an exhaust passage of an internal combustion engine. Specifically, it relates to an exhaust gas purification device provided with a particulate filter for trapping particulate matter in exhaust gas discharged from an internal combustion engine. [0002] In addition, this application claims the priority based on Japanese Patent Application No. 2013-249169 for which it applied in Japan on December 2, 2013, The whole content of this application is taken in as a reference in this specification. Background technique [0003] It is generally known that exhaust gas from an internal combustion engine contains particulate matter (PM: Particulate Matter) mainly composed of carbon, dust containing incombustible components, and the like, and causes air pollution. Therefore, for the emission of particulate matter, the amount of hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (...
