EXHAUST GAS PURIFIER FOR INTERNAL COMBUSTION ENGINE |
摘要 |
In an exhaust gas purification apparatus for an internal combustion engine which is provided with a selective reduction type catalyst disposed in an exhaust passage of the internal combustion engine, a reducing agent supply device for supplying an ammonia derived reducing agent to a portion of the exhaust passage at the upstream side of the selective reduction type catalyst, and a mixing device disposed in a portion of the exhaust passage at the upstream side of the selective reduction type catalyst and at the downstream side of the reducing agent supply device, the present invention has a problem to remove solid matter derived from the reducing agent, which is adhered to or deposited on the mixing device, in a suitable manner. In order to solve this problem, the present invention has a temperature raising device disposed in a portion of the exhaust passage upstream of said mixing device so as to blow a flame to said mixing device. |
