Abstract

The invention discloses an EGR tube seal ring comprising a seal ring body which is circular. The cross section of the seal ring body is rectangular; four corners of a rectangle are all chamfered; the inner and outer sidewalls of the seal ring body are evenly provided with a plurality of paired projections; each projection is semi-cylindrical; two ends of every projection are transitionally connected with the sidewall of the seal ring body through semispherical shapes. The EGR tube seal ring is reasonable in design and good in sealing performance, and exhaust gas emission efficiency can be effectively improved so that pollution is reduced.

Description

technical field [0001] The invention relates to a sealing ring used in auto parts, in particular to an EGR pipe sealing ring. Background technique [0002] In the process of modern industrial production becoming more and more developed, automobiles have become an indispensable means of transportation for people's lives, and their output is increasing day by day. With the emphasis on personal and traffic safety issues, people pay more and more attention to the quality of cars. In the structure of automobiles, EGR is an exhaust gas recirculation system, which is an exhaust purification device for nitrogen oxides NOx, one of the harmful gases in engine exhaust. The sealing effect of the EGR pipe directly affects the efficiency of exhaust gas emission and purification. If the sealing effect is not good, more waste will be discharged into the atmosphere, which will have a certain impact on the environment. Contents of the invention [0003] The purpose of the present inve...
