Variable Valve Actuation allows real-time adjustments to valve opening and closing, maintaining accurate control of valve motion. By creating a hydraulic link between the cam and the valve, VVA precisely tunes the engine across its operating range. This allows the engine designer to extract superior performance from the engine.
Variable Valve Actuation (VVA) - DieselNet
Variable Valve Actuation (VVA) or Valve-Event Modulation (VEM) are general terms that can be used to describe a range of technologies used to add flexibility to the engine’s valve train by enabling variable valve event timing, duration and/or lift.
