摘要:
An improved cylinder head arrangement for a multiple valve internal combustion engine wherein the cylinder head supports three intake valves that communicate with a common intake passage extending through one side of the cylinder head. An associated manifold is affixed to the cylinder head and has two inlet openings and a transition portion that forms a smooth transition from these two inlet openings to the single intake passage of the cylinder head.
