Abstract
The internal combustion engine includes a head cover, a cylinder head, an exhaust-side valve guide, an exhaust-side valve, and a valve operating mechanism. The head cover and the cylinder head define an accommodation space for accommodating the valve operating mechanism. The cylinder head includes an exhaust port and an exhaust-side fixing hole. The material of the exhaust-side valve guide is a porous material. The exhaust-side valve guide is inserted into the exhaust-side fixing hole. A portion of the exhaust-side valve guide protrudes from the exhaust-side fixing hole into the accommodation space. The exhaust-side valve guide is open at an outer peripheral face of the exposed portion, and includes a flow passage extending from the exposed portion to the insertion portion.
