Electromagnetic drive valve control of the gas-distribution gear of an internal-combustion engine

Abstract

A method to control a resonant electromagnetic gear with a polarized magnetic system that pro vides the minimal seating speed of the armature and, correspondingly, of the valve is considered. A complex mathematical model of the drive is proposed. The device characteristics for different values of the viscous resistance coefficient are investigated. Results of mathematical modeling are compared with the experimental data, and the adequacy of the mathematical model is confirmed. The results of experimental investigations of the control device that implements the proposed method are presented.
