Abstract:In order to solve the problem that the exhaust manifold
and the pipe pressure are insufficient due to the unreasonable sealing method
of the exhaust manifold,the CAE comparison calculation method is used to
analyze the influence of different sealing methods and bolt materials on the sealing of
exhzust manifold.
Key words:engine; exhaust manifold; seal; modal analysis
