The utility model provides an air ring assembly of an automobile engine. Multiple circles of protrusions are arranged on the inner wall of a shaft neck of an air ring, and a rubber sealing ring is vulcanized through the multiple circles of protrusions, wherein the rubber sealing ring extends in the axial direction and forms a horn mouth; the opening angle a of the horn mouth ranges from 10 degrees to 50 degrees; the air ring is made of extrusion aluminum-type materials, and the air ring is formed through the procedures of rounding, sizing and welding. The air ring is formed into the air ring assembly through the vulcanization of the rubber sealing ring, the rubber part of the air ring assembly is arranged on a fan guard of a radiator in a pressed mode in the axial direction and attached to the fan guard of the radiator tightly, in the assembling process, the vulcanized air ring assembly is assembled on the fan guard of the radiator in a pressed mode in advance, then the air ring assembly is assembled on a corresponding support of the engine integrally, the assembly efficiency is improved, compared with an existing structure, the sealing effect is better, and the appearance is flatter; by means of the arrangement of the multiple circles of protrusions, the rubber contact area is enlarged, the rubber adhesive force is strengthened, the rubber is prevented from falling off, and the profile rigidity of the air ring can be strengthened as well.
