To make innocuous toxic matter in exhaust emission flowing to the downstream side from a particulate filter in the case of backflow of exhaust emission by preventing most of fine particles from being collected on one side of a partition wall of a particulate filter, and exerting the oxidizing and removing action on the fine particles on the downstream of exhaust emission from the partition wall so that the action of sufficiently transmitting the action of oxidizing and removing fine particles collected on the partition wall by active oxygen is transmitted to all of the fine particle to inhibit the fine particles from being deposited on the partition wall.
An oxidizer 61 for emitting active oxygen for oxidizing fine particles 62 temporarily collected on the partition wall 54 of the particulate filter 22 is supported on the partition wall 54, the exhaust emission flow passing through the partition 54 is reversed to disperse the fine particles collected on the partition wall 54 to one side of partition wall and the other side of the partition wall, thereby lowering the possibility that the fine particles collected on the partition wall 54 are deposited without being oxidized and removed, and a filter 80 as a means for making innocuous toxic component in exhaust emission is disposed on the downstream of the exhaust emission flow from the particulate filter 22.
