ABSTRACT:
An arrangement of oil passages to a valve system can reduce the number of parts required thereby lowering the manufacturing cost. The oil passages to a valve system of an internal combustion engine are integrally formed with the cylinder block and a cylinder head. These oil passages are arranged along the outer surfaces on a side opposed to a cylinder liner and a combustion chamber relative to a valve system drive transmission.
