Abstract

자동차 배출가스의 정화효율을 높이고, 외부의 열적충격 및 열적노화형상에 대한 내구성을 증대시킨 촉매변환장치를 얻기위하여, 외형을 형성하는 하우징과, 상기 하우징내에 위치하여 유입된 유해가스를 촉매작용으로 정화하는 담체와, 상기 담체와 상기 하우징사이에 삽입되어 담체의 열적충격 및 열화현상을 방지하는 완충재 및 단열재를 구비한 자동차용 촉매변환장치에 있어서, 상기 담체가 규칙적인 통로를 구비한 벌집형담체와, 불규칙적인 통로를 구비한 다공성 세라믹담체로 이루어지고, 상기 벌집형담체와 다공성 세라믹담체가 교대로 설치된 다단적층식 촉매변환장치.In order to increase the purification efficiency of automobile exhaust gas and to obtain a catalytic converter having increased durability against external thermal shock and thermal aging, the housing forming the external shape and the harmful gas introduced into the housing are catalyzed. A catalytic converter for automobiles comprising a carrier for purification and a buffer and a heat insulating material inserted between the carrier and the housing to prevent thermal shock and deterioration of the carrier, wherein the carrier has a honeycomb carrier having a regular passage. And a porous ceramic carrier having irregular passages, wherein the honeycomb carrier and the porous ceramic carrier are alternately installed.
