Claims

[Scope of utility model registration request]

An inlet 2 for engine exhaust and an outlet 3 for combustion-processed exhaust are formed in the case 1, and an exhaust circulation chamber 4 is formed in the case 1 from the population 2 to the outlet 3. This catalytic combustion processing device for engine exhaust gas is characterized in that porous vent type catalysts 5 are arranged respectively, and the catalysts 5 on the upper side in the flow direction are coarsely formed and the catalysts 5 on the lower side in the flow direction are finely formed.
