PARTICULATE MATTER TREATING DEVICE

摘要

Aggregation of the particulate matter is facilitated. A particulate matter processing apparatus (1) comprises an electrode (5) which is provided in an exhaust gas passage (3) of an internal combustion engine, which extends from a wall surface of the exhaust gas passage (3) toward an inner side of the exhaust gas passage (3), which is bent at a bent portion (51) toward an upstream side or a downstream side in a flow direction (B) of an exhaust gas, and which extends toward the upstream side or the downstream side in the flow direction (B) of the exhaust gas, wherein the electrode (5) is formed so that a field intensity, which is provided between the electrode (5) and the wall surface of the exhaust gas passage (3) on the upstream side, is larger than that provided on the downstream side.
