Cylinder Deactivating Roller Finger Follower

As a quality-oriented organization, we are focused to manufacture and supply our customers excellent quality Cylinder Deactivating Roller Finger Follower from Dharuhera, Haryana, India. The offered Cylinder Deactivating Roller Finger Follower (DRFF) is an advanced variable valve actuation technology that enables cylinder deactivation during engine operation. The cylinder deactivation event is achieved through a rocker arm mechanism that works with a 3-lobe cam. The cam switches between full- and zero-lift cam profiles via corresponding rocker arm modes. The system includes a deactivating rocker arm (deactivation roller-slider finger follower) and an oil control valve (OCV) for hydraulic actuation.
The DRFF and OCV can be implemented in engines employing traditional deactivation schemes on fixed cylinders for fuel economy improvement. Additionally, the valve train components are essential elements of the Delphi-Tula Dynamic Skip Fire (DSF) Cylinder Deactivation System.
