摘要

PURPOSE: An oil control valve structure of an engine variable valve lift is provided to facilitate the assembly of an engine and the arrangement of an oil control valve, to make an oil pump smaller, and to reduce the amount of engine power usage. CONSTITUTION: An oil control valve structure of an engine variable valve lift includes a cylinder body (32). The cylinder body includes one cylinder head (33) and a timing chain chamber. The timing chain chamber on which a timing chain (341) is mounted extends to the cylinder head upwardly. An oil control valve mount (334) and a rocker arm chamber (35) are installed on the cylinder head. The rocker arm chamber includes a cam unit (351), a rocker arm unit (352), and a valve unit (353). The rocker arm unit includes an oil control driving unit (354). The oil control driving unit is controlled by an oil control valve (4).
