ABSTRACT
An innovating solution for throttle-free load control for spark-ignition engines is variable valve timing system. In this paper is presented a cam synthesis and optimization, using the analytic method, of the valve timing mechanism with three elements and continuous valve lift variation. It is also presented the numerical algorithm for the mechanism’s synthesis and dimensionally optimization.
