压电陶瓷阀特性的研究

A study of the characteristic of a piezoelectric ceramic valve

本文设计出以压电陶瓷作为驱动元件的开关阀 ,并对其响应特性进行了分析 ,实验证明了理论分析的正确性 ,文中指出该开关阀可替代电磁阀应用于电控燃油喷射系统 ,以实现定时、精确喷射燃油。

This paper describes the design of a switch valve driven by piezoelectric ceramics and analyses its response characteristic.The experimental results prove that the theoretic analysis is right.This switch valve can be applied to an electric control fuel system to realize timing and accurate injection.
