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.
