摘要:
A wall flow type particulate filter (24) adapted to be arranged in an exhaust passage of an internal combustion engine in which combustion is performed in an excess of oxygen carries a solid acid. The solid acid has an acid strength which is higher than the acid strength of sulfurous acid and lower than the acid strength of sulfuric acid.
