Abstract

A 3D numerical simulation model of high-speed solenoid valve (HSV) for electronic control fuel injection system (ECFIS) has been developed. The model has been validated experimentally with acceptable maximum errors of 2% and 8.7% in closure response time and open response time, respectively. Effect of assembly parameters such as residual air gap, maximum lift of valve stem, mass of the moving parts, spring stiffness, and spring pretightening force on dynamic response characteristics of HSV has been analyzed in detail using the simulation model, and influence rules of various parameters on dynamic response characteristics have been established. Moreover, the correlation between interaction factors of main influence factors and dynamic response characteristics of HSV has also been analyzed. It is concluded that residual air gap, maximum lift of the valve stem, and spring pretightening force are the main influencing factors on dynamic response characteristics of HSV, and there are obvious interaction effects between them; when two or three of these main influencing factors are adjusted at the same time, the interaction effects should be considered.
