Deformation prevention structure of exhaust manifold for internal combustion engine

摘要

SUMMARY OF THE INVENTION It is an object of the present invention to provide an internal combustion engine capable of preventing thermal deformation of an exhaust manifold to maintain airtightness between a cylinder head and an exhaust manifold to prevent leakage of exhaust gas, Thereby providing an exhaust manifold thermal deformation preventing structure.;The exhaust manifold thermal deformation preventing structure for an internal combustion engine according to the present invention prevents deformation of the exhaust manifold mounted on the exhaust port side of the cylinder head with the fastening member by combustion heat so that airtightness is always maintained between the cylinder head and the exhaust manifold. The plate portion is provided with thermal deformation preventing means.
