摘　　要：在电控喷油器电磁动态工作性能研究基础上,分析了影响电磁动态特性的主要因素。通过测量驱动电路中串联小电阻的电压变化,得到电磁线圈电流响应特性。线圈安匝数和磁极气隙是影响电磁动态特性的主要因素。结合实验结果提出喷油器结构改进设计原则,对结构改进后的喷油器电磁响应特性进行了实验验证。结果证明电磁响应特性得到了提高,开启响应时间由原来的1.4 ms提高到1.1 ms,关闭响应时间缩短1.4 ms。We first studied the dynamic electromagnetic performance of an electronic-control fuel injector, then we analyzed the influence factors on it. By measuring the voltage change of a resistance which is series-wound in the driving circuit, the current response of electromagnetic loop was obtained. Ampere-turn and magnetic gap is the main influencing factors. According to the experimental data, we put forward measures for improving the structure of fuel injectors. Test data show that the electromagnetic property is indeed improved： opening time of valve changes from 1.4 ms to 1.1 ms and its closing time is reduced by 1.4 ms.
