ことを特徴とする触媒コンバータ。 A reduction catalyst or a three-way catalyst and an oxidation catalyst are installed along the flow direction of exhaust gas in a shell having an exhaust gas inlet and a discharge port, and a secondary air introduction nozzle is installed in the space formed between these two catalysts. In the catalytic converter, the effective cross-sectional area for exhaust gas purification of the oxidation catalyst is determined from the effective cross-sectional area for purifying exhaust gas of the reducing catalyst or three-way catalyst according to the secondary air injection distribution area of the secondary air introduction nozzle. A catalytic converter characterized by its small size.
