What does engine CVVL mean?

[SanSara]

Engine CVVL stands for Continuous Variable Valve Lift. The details are as follows: 1. Based on control effects, variable valve lift technology can be divided into Continuous Variable Valve Lift (CVVL) and Discrete Variable Valve Lift (DVVL). Traditional gasoline engines have fixed, non-variable valve lift. 2. Function: CVVL technology can reduce fuel consumption. This is because, under small loads, lift control replaces throttle control, reducing throttle losses, increasing intake pressure, maintaining higher cylinder pressure, and minimizing the work consumed during the gas exchange process, thereby lowering pumping losses.
