The invention relates to the technical field of automobile exhaust treatment and discloses an improved three-way catalyst for automobile exhaust treatment. The improved three-way catalyst comprises anouter interlayer, wherein a heat insulating layer is fixedly mounted in the outer interlayer, an inner interlayer is fixedly mounted in the heat insulating layer, a liner is fixedly mounted in the middle of the inner side surface of the inner interlayer, and a ceramic carrier is fixedly mounted in the middle of an inner cavity of the liner. According to the improved three-way catalyst for the automobile exhaust treatment, purification holes are circumferentially formed in the ceramic carrier, when the purification holes are blocked, at the moment, the whole three-way catalyst has the phenomenon of unsmooth exhausting, the ceramic carrier is blocked at the moment, so that gas can push the ceramic carrier to move backwards, a reset spring is compressed at the moment to drive the ceramic carrier to move backwards, a
