Abstract
Continuous Variable Valve Event and Lift (VVEL) system which improves three major engine performances (fuel consumption/ emission/ driving performace) in well-ballanced manner is developed. This paper introduces outline of the VVEL system, and describes the principle of operation/ transformation and the mechanism of improvement in engine performance of this technology.
