Abstract (en)
In an exhaust gas purifier provided with a collecting material for collecting particulate matters contained in exhaust discharged from an internal combustion engine, by restraining generation of ash, a pressure loss of exhaust due to clog the collecting material is prevented. In an exhaust gas purifier for an internal combustion engine which is provided with a collecting material for collecting particulate matters contained in exhaust discharged from the internal combustion engine, ash traps (80, 81) for absorbing phosphorous (P) in exhaust gas are provided upstream of a particulate filter (22). The ash traps (80, 81) load with basic metal. The formation of ash due to combine Phosphorous (P) with calcium (Ca) and to be concentrated in the particulate filter (22) is restrained. <IMAGE>
