Abstract: A roller pin decoupling type cylinder deactivation (CDA) system includes a roller rocker arm, rocker shaft, a camshaft, and an actuation valve. When oil is not supplied to a rocker shaft sub passage of the rocker shaft and a hydraulic pressure is released from the actuation valve, the roller and the pin are not restrained so that the CDA is generated. Thus, the roller is switched to a non-rotating state and a rotating state according to non-operation and operation of the CDA. In particular, a degree of freedom of control over a system mechanism is imparted due to restriction control of the roller pin through the actuation valve which is operated by a hydraulic pressure, which makes it possible to improve operation efficiency for each engine operating condition.

Abstract: A CDA operation interlocked oil jet system connects the OCV for supplying the oil for the operation of the CDA of the rocker arm and the oil jet check valve configured to perform the oil jet injection toward the piston of the engine by the bypass oil extension line, and includes the control unit configured to control the OCV so that the bypass oil extension line is open when the CDA is operated, so that it is possible to control the oil jet injection by dividing the bypass function of the OCV into the operation and non-operation of the CDA to use the bypass function of the OCV accordingly, and in particular, the oil jet injection to the cylinder is performed when the CDA is not operated, and then stopped in the deactivated cylinder that occurs when the CDA is operated, so that it is possible to prevent the oil-up phenomenon and reduce the capacity of the oil pump by reducing or blocking the unnecessary injection oil of the oil jet.

Abstract: A CDA rocker arm system to which a dual oil supply line is applied uses an oil supply line comprised of a primary oil line connected from an OCV to one side of a rocker pin to supply the oil and a secondary oil line connected from the OCV to the other side of the rocker pin to supply the oil, and opens the primary oil line and blocks the secondary oil line when a control unit operates a cylinder deactivation (CDA) under the control of the OCV, whereas the CDA rocker arm system opens the secondary oil line and blocks the primary oil line when the CDA is not operated, so that the rocker pin may be converted into the pin disengaged and pin engaged states by the hydraulic operation of the oil supplied in both cases in which the CDA is operated and not operated under an oil supply direction control of the OCV.
