EXHAUST MANIFOLD AGGREGATED SECTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an exhaust manifold aggregated section structure capable of preventing generation of cracking by relieving stress concentration by a thermal elongation difference in the center of an aggregated section without increasing the number of parts. SOLUTION: On an inner wall of a terminal section on the downstream side of an exhaust pipe 17 forming the aggregated section, thick-wall portions 29 are provided respectively along each axis 23 to form a thick-wall area of the pipe.
