。 The catalytic converter includes an inlet connected to an inflow path of exhaust gas, an outlet connected to an outflow path, and a catalyst carrier interposed between the inlet and the outlet. The inlet and outlet sections are offset from each other such that the inlet and outlet sections face the catalyst support at a required angle θ 1
The axial center line of the catalyst carrier is inclined by a required angle θ 2 with respect to the axial center line of the exhaust gas inflow path and outflow path. The values of angles θ 1 and θ 2 are respectively 7 degrees ≦ θ 1 ≦ 30 based on fluid theory.
A catalytic converter, characterized in that the catalytic converter is set to satisfy 35 degrees≦θ 2 ≦55 degrees.
