EXHAUST MANIFOLD MOUNTING PART STRUCTURE FOR CYLINDER HEAD

摘要

PROBLEM TO BE SOLVED: To provide an exhaust manifold mounting part structure for a cylinder head barely affected by thermal deformation of an exhaust manifold. SOLUTION: In this exhaust manifold mounting part structure for the cylinder head, screw holes 8 which are threadedly engaged with stud bolts (bolts) arranged around an outlet 6 of an exhaust port 5 and fixing the exhaust manifold on a side surface 3a of the cylinder head 3 are arranged at every outlet interval parts 9 of adjoining exhaust ports 5 alternately in both sides of a line segment B connecting centers of outlets 6 of adjoining exhaust ports 5 along side surface 3a. A screw hole 8 arranged in the outlet interval part 9 where an oil drop hole 16 passing through the cylinder head 3 is provided is arranged in a further side from a cylinder block 2 in which cylinders 4 are provided in relation to the line segment B connecting centers of outlets 6 of adjoining exhaust ports 5 along side surface 3a.
