Valve actuating arrangement for engine.

摘要

A valve arrangement for a cylinder head assembly employing three intake valves and two exhaust valves for each cylinder. Not all of the intake valves reciprocate along parallel axes and hydraulic adjusters are operatively associated with the camshafts and rocker arms that operate the valves from the respective camshafts. The geometric relationship of the valves is chosen so as to maintain a compact and effective combustion chamber configuration and facilitate machining of the bores in which the hydraulic adjusters are positioned.
