Oil supply structure for continuous variable valve timing apparatus and cylinder head employing the same

Abstract

An oil supply structure of a continuously variable valve timing apparatus includes: a first oil filter to receive and filter oil from a main gallery; a first oil control valve to receive oil from the first oil filter; a first continuously variable valve timing apparatus to receive oil from the first oil control valve; a second oil filter to receive and filter oil from the main gallery; a second oil control valve to receive oil from the second oil filter; a second continuously variable valve timing apparatus to receive oil from the second oil control valve; and an oil supply line in a cylinder head, that fluidly connects the main gallery, the oil filters, the oil control valves, and the continuously variable valve timing apparatuses. The cylinder head includes the oil supply line, and various holes for the components of the oil supply structure to be disposed therein.
