Variable Valve Event and Lift — commonly shortened to VVEL on individual specs sheets — is an innovative timing control system developed by Nissan and adapted to the automaker's luxury INFINITI vehicles.
As seen in the 2018 Q70, VVEL technology utilizes hydraulic-operated timing processes combined with electronically managed consumption functions to simultaneously improving fuel efficiency while also reducing emissions. For example, thanks to the proprietary mechanics, the brand’s flagship sedan is able to earn an impressive 18 MPG in the city and 25 MPG on the highway.
In a standard engine, air is restricted from entering the intakes for longer intervals. However, a VVEL-equipped powertrain allows air to flow through the wide throttle opening — which, unlike other setups, doesn’t close when the driver depresses the pedal. From there, the oxygen is admitted into the combustion chamber at a more precise rate determined by the intake valves. Because the draft sits directly outside the cell, the throttle response is instant.
