Three way catalyst converter carrier

The utility model relates to a three way catalyst converter carrier, casing and the carrier of setting in the casing including the drum, the casing with be equipped with the liner between the carrier, its characterized in that, the carrier is inside to be equipped with two catalysis beds and air inlet, be located the inside top of carrier for reducing catalyst catalysis bed, be located the inside below of carrier for oxidation catalyst catalysis bed, reducing catalyst catalysis bed with be equipped with the air chamber between the oxidation catalyst catalysis bed, the air inlet terminal surface of carrier is toward outer bellied wave terminal surface, the utility model discloses with the design of the terminal surface of carrier air inlet for toward outer bellied wave terminal surface, under the unchangeable condition of section size, the hole count is increased to 600 meshes-800 meshes, has improved porosity greatly, gas flow is even, full play holistic conversion effect.
