Hyundai Accent (HC) (2017 - 2022) Service Manual: Variable Force Solenoid (VFS)

- Description CVVT (Continuous Variable Valve Timing) system advances or retards the valve opening and closing timing of the intake or the exhaust valve in accordance with the ECM control, calculated by the engine speed and the load. The CVVT control causes a valve over-lap or under-lap between the intake valve and the exhaust valve. This improves fuel efficiency, reduces exhaust gases (NOx, HC) and enhances the engine performance, thanks to reduced pumping loss, internal EGR (Exhaust Gas Recirculation) release, improved combustion stability, and increased volumetric efficiency.
