摘要 |
An exhaust gas purifying apparatus for an internal combustion engine is provided with: a first catalyst (234) which is disposed in an exhaust passage of the internal combustion engine (200); a second catalyst (235) which is disposed in the exhaust passage on a downstream side of the first catalyst; a reducing agent supplying device (233) which is disposed on an upstream side of the first catalyst and which is configured to supply a reducing agent into the exhaust passage; and a reducing agent supply controlling device (100) which is configured to control the reducing agent supplying device such that an air-fuel ratio on the upstream side of the first catalyst becomes momentarily rich. |
