Abstract (en)
[origin: EP2960457A1] An exhaust purification device having high exhaust purification performance can be implemented with a simple structure. In an exhaust purification device in which catalyst is carried in a plurality of honeycomb bodies that are arranged in series so as to be spaced from one another through gaps, a single outer tube 55 constituting a part of an exhaust passage of an exhaust device 40 of an internal combustion engine is provided, a first honeycomb body 81, a second honeycomb body 82 and a third honeycomb body 83 are accommodated in this order from an upstream side of exhaust in the outer tube 55, the catalyst is carried in passages of the first honeycomb body 81, the second honeycomb body 82 and the third honeycomb body 83, the second honeycomb body 82 is shared as the same part as the third honeycomb body 83, the first honeycomb body 81 has the same outer diameter as the second honeycomb body 82 and the third honeycomb body 83, and the number of cells per unit area of cells comparted in a gird form in the first honeycomb body 81 is smaller than the number of cells in the third honeycomb body 83.
