着した触媒コンバータに於て、上記触媒担体の中
央部の目を密に形成し、触媒担体の周縁部の目を
疎に形成すると共に、触媒担体と上流側に、エン
ジンの運転状況に応じて触媒担体の中央部又は周
縁部への排気ガスの流れを制御する制御弁を設け
たことを特徴とする触媒コンバータ。 In a catalytic converter in which a catalyst carrier is installed in a shell that has diameter-reduced portions at both ends, the openings in the central part of the catalyst carrier are formed densely, and the openings in the peripheral part of the catalyst carrier are sparsely formed. A catalytic converter characterized in that a control valve is provided on the carrier and upstream thereof to control the flow of exhaust gas to the center or peripheral portion of the catalyst carrier depending on the operating conditions of the engine.
