摘　　要：排放法规的日益苛刻,用压电陶瓷微制动元件作为共轨喷油器的执行器成为发展趋势,通过对压电执行器的性能进行大量试验,得到的试验数据为共轨喷油器总成设计提供依据,油泵台架试验证明,研制出的共轨喷油器总成响应迅速,油量均方差及开启延迟均优于电磁铁喷油器总成。In order to meeting the increasingly demanding emissions regulations,the piezoelectric actuator became a trend as the injector actuator.The design of the piezoelectric common-rail injector was provided by the piezoelectric actuator testing data.The pump bench test shows that the piezoelectric injector has some advantages than the solenoid injector,such as the response of the injector,mean variance of the fuel quantity,open delay of the injector.
