徴とする排気後処理装置。 The particulate matter in the exhaust gas discharged through the exhaust passage of the internal combustion engine is captured by a particulate matter trap, and the particulate matter is incinerated by supplying high-temperature gas from the upstream side of the particulate matter trap. This is an exhaust after-treatment device that regenerates particulate traps, in which the exhaust passage upstream of the particulate trap is divided into two parts, a capture exhaust passage and a regeneration exhaust passage, which are switched by a valve. and the temperature of the exhaust gas flowing into the particulate trap is made different between when it passes through the regeneration exhaust passage and when it passes through the capture exhaust passage. An exhaust after-treatment device characterized in that the exhaust gas that has passed through is used as the high-temperature gas.
