Flexible connection structure of exhaust manifold and exhaust pipe

摘要

In order to improve the efficiency of the connecting operation connecting the flange of the exhaust manifold and the flange of the front exhaust pipe, and to reduce the cost, a sealing part is formed integrally with the connecting end of the exhaust manifold flange, and the corresponding front exhaust By fixing the sealing part of the pipe flange through the bolts and nuts, the process is reduced by eliminating the flexible seal used in the flange connection part of the related art, thereby improving the efficiency of the connection work and reducing the cost. The sealing part corresponding to the connection end of the exhaust manifold 10 and the front exhaust pipe 12 is formed, and the flange 14 formed in these exhaust manifold 10 and the front exhaust pipe 12 is carried out. 16 connected to each other via a buffer fastening means, corresponding to the sealing portion 18 of the front exhaust pipe 12. It is characterized in that it is formed integrally with the exhaust manifold 10 side sealing part 30 to the connection end of the exhaust manifold 10.
