A variable valve actuation (VVA) apparatus comprises an eccentric rotary (ER) cam fixed to a driving shaft for rotation therewith, a pivotal valve operating (VO) cam, a rocker arm having a first arm and a second arm, a control rod having an eccentric control cam, and a crank arm. The eccentric control cam supports the rocker arm for pivotal motion. The crank arm interconnects the ER cam and the first arm of the rocker arm. A link interconnects the second arm of the rocker arm and the VO cam.
