Title:

EXHAUST GAS PURIFICATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2020/071389

Kind Code:

A1

Abstract:

In an exhaust gas purification device (3) for collecting and burning particulate matter contained in exhaust gas from an internal combustion engine (1), noble metal is made to be supported inside a partition wall of a wall flow type carrier (6) having an inlet cell (4) and an outlet cell (5). An inlet upstream section (14) on which a catalyst is supported is provided upstream of the side of a partition wall surface, which faces the inlet cell (4). An outlet downstream section (15) on which a catalyst is supported is provided downstream of the side of the partition wall surface, which faces the outlet cell (5). As a result, exhaust gas purification performance is efficiently enhanced.
