Exhaust gas treatment apparatus for an internal combustion engine (10) includes: an exhaust gas treatment unit (21) arranged in an exhaust passage (18a) of said engine (10), the exhaust passage being configured such that i) exhaust gas flowing along a part of a wall face (18e), which defines the exhaust passage, burbles away from the part of the wall face in an exhaust gas burble zone (Z 1 ) and ii) as a result of said burble, exhaust gas disproportionately flows into the exhaust gas treatment unit or the amount of exhaust gas flowing into said unit reduces; and a plasma actuator (23) arranged at the part of the wall face of the exhaust passage in the exhaust gas burble zone, the plasma actuator (23) being configured to generate air current toward the exhaust gas treatment unit along the part of the wall face in exhaust gas inside the exhaust passage. |
