Claims

[Scope of utility model registration request]

A pair of catalyst beds are installed in the shell, separated by a desired distance in the flow direction of the exhaust gas, and a secondary air supply extending in a direction perpendicular to the main axis of the exhaust gas is provided in the space formed between the two catalyst beds. In a catalytic converter having pipes, the side periphery of the secondary air supply pipe facing the catalyst bed in the previous stage←
A catalytic converter characterized in that a plurality of secondary air ejection holes are formed in the longitudinal direction of the secondary air supply pipe in a direction parallel to the main axis of exhaust gas, a direction at 45 degrees, and a direction perpendicular to the main axis of exhaust gas.
