摘要:
PROBLEM TO BE SOLVED: To provide an exhaust gas purifying device equipped with a purifying catalyst capable of efficiently combusting PM at a lower temperature than before. SOLUTION: In the exhaust gas purifying device of an internal combustion engine equipped with DPF 1 provided in the exhaust passage of the engine and having the purifying catalyst capturing PM contained in the exhaust gas of the engine and purifying the captured PM, the purifying catalyst is characterized in that the particle size D90 of the purifying catalyst, at the time when the cumulated distribution from the small particle size side in the particle size distribution of the purifying catalyst becomes 90%, is 2 μm or below.
