| 摘要 |
The present invention relates to an exhaust gas treatment apparatus for an internal combustion engine, capable of preventing at least a reduction in the amount of exhaust gas. The exhaust gas treatment apparatus comprises: an exhaust gas treatment unit disposed in an exhaust passage of the internal combustion engine, the exhaust passage being configured such that i) exhaust gas flowing along a part of a wall face, which defines the exhaust passage, is separated from the part of the wall face in an exhaust gas burble zone and ii) since the exhaust gas is separated from the part of the wall face of the exhaust passage in the exhaust gas burble zone, the exhaust gas disproportionately flows into the exhaust gas treatment unit or the amount of exhaust gas flowing into the exhaust gas treatment unit is reduced. A plasma actuator is also provided at the part of the wall face of the exhaust passage in the exhaust gas burble zone, the plasma actuator 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. |
