摘　　要：阐述一种用于柴油机电控喷油系统的新型电液开关阀。该阀利用压电陶瓷驱动 ,位移采用液压方式放大。通过系统设计、性能分析以及模拟计算 ,结果表明 ,该阀的响应特性明显优于电磁开关阀。A new kind of electro hydraulic on off valve is expatiated on for fuel injection system of electronic controlled diesel engine. It is actuated by piezoelectric ceramics with its displacement amplified by hydraulic means. Design of the system and analysis of its performance are followed by simulation. The results prove its responding characteristic superiority to electromagnetic on off valve.
