Abstract
A device configured for controlling lubrication of rocker arms of an engine with a CDA function, may include valves, wherein the opening/closing state of valves is varied in accordance with an operation state of a vehicle, to which the device is applied, and then, amounts of oil supplied to respective rocker arms are adjusted. Accordingly, the oil pressure and oil pumping capacity of a main gallery may be reduced and then, an enhancement in fuel economy may be achieved. Furthermore, lubrication performance may be secured through an increase in oil supply amount.
