PURPOSE: A lubrication structure for an engine with a CVVL(Continuous Variable Valve Lift) system is provided to prevent the loss of hydraulic pressure of oil supplied to a control shaft located higher by setting independent oil flow paths for control and drive shafts. CONSTITUTION: A lubrication structure for an engine with a CVVL system comprises a cylinder head(10), a cam carrier(20), a drive shaft(30), a control shaft(40), an actuator(50), a drive shaft flow path(60), a control shaft flow path, and an actuator flow path(80). The cam carrier is installed on the top of the cylinder head. The drive shaft is installed in the cam carrier. The control shaft interlocks with the drive shaft in order to control the valve lift. The actuator controls the control shaft. The drive shaft flow path, the control shaft flow path, and the actuator flow path are formed independent and provide oil to the drive shaft, the control shaft, and the actuator, respectively. |
