EXHAUST GAS PURIFYING DEVICE

摘要

An exhaust gas purifying device which can efficiently purify HC, CO, and particulate matter contained in exhaust gas discharged from an internal combustion engine, allows regenerating processing at a temperature lower than the temperature used in conventional devices, and is inexpensive. An exhaust purifying device (10) for purifying exhaust gas discharged from an internal combustion engine is provided with a first purifying body (13) provided in an exhaust gas flow path and purifying HC and CO in exhaust gas, and also with a second purifying body (14) provided in the exhaust gas flow path at a position downstream of the first purifying body (13) and purifying particulate matter in the exhaust gas having passed through the first purifying body (13).  The second purifying body (14) is provided with a filter capable of capturing the particulate matter, and also with a particulate matter oxidation catalyst carried by the filter and comprising an oxygen releasable composite oxide having at least Ag carried thereon.
