Abstract
A cylinder head includes a combustion chamber recess on a lower surface, an exhaust port with downstream and upstream side channels, and downstream and upstream liners respectively inserted into the downstream and upstream side channels. The downstream side channel has an open end at a side surface of the cylinder head and an opposite end sealed by a bottom wall. The upstream side channel has an end open to the combustion chamber recess and an opposite end connected to a side portion of the downstream side channel. The downstream side liner includes a generally tubular member with a linear axis and has an insertion end abutting the bottom wall. The downstream side liner has a connecting hole in a side portion facing the upstream side channel and engaged by the upstream side liner, which also includes a generally tubular member.
