OHC TYPE INTERNAL COMBUSTION ENGINE

摘要

PURPOSE: To improve conventional structure that takes a lot of man-hours in manufacture since halved camshaft bearing holding parts are formed by using joint faces of separately produced members such as a cylinder head cover and a cylinder head to facilitate production of a bearing holding part and installation work of a camshaft, in an OHC type internal combustion engine whose rotating camshaft interlocked with a crankshaft is disposed on a cylinder head. CONSTITUTION: A camshaft holder for holding the camshaft to be rotatable is produced separately from the cylinder head or cylinder head cover, and the camshaft holder is tightened together by stud bolts passing through a cylinder.
