触媒コンバータ。 A metal carrier carrying a catalyst is inserted into a cylindrical outer cylinder and fixed therein, and a first case connected to the exhaust manifold side is fitted into the upstream part of the outer cylinder. The downstream end and the outer cylinder are joined by welding the entire circumference, and a case of a second case connected to the exhaust pipe is fitted to the downstream part of the outer cylinder, and the second case is connected to the exhaust pipe.
The upstream end of the case and the outer cylinder are joined by welding the entire circumference, and the fitting distance between the first case and the outer cylinder is equal to the fitting allowance between the second case and the outer cylinder. The exhaust manifold catalytic converter is characterized by being larger than the conventional one.
