摘要：

针对目前电控汽油喷油器生产过程中存在材料性能不稳定、生产效率低、产品综合性能较差等问题，将金属注射成形技术引入到电控汽油喷油器的制造过程中,根据金属注射成形的技术特点及电控汽油喷油器性能要求,选择了铁基纳米晶软磁合金材料进行样品试制。通过仿真和试验手段对金属注射成形技术生产的样品和传统产品进行了综合性能对比分析,结果表明,采用金属注射成形技术生产的电控汽油喷油器在电磁性能、动态响应特性和动态流量特性等方面与传统工艺生产的样品相比具有较大的优势。

Abstract:

In view of the problems such as unstable material property, low production efficiency, poor comprehensive performance of the products, MIM technology was introduced into the electronic gasoline injector's manufacturing process. According to the technical characteristics of MIM and performance requirements of the injector, a kind of Fe-based nano-crystalline soft magnetic alloy was used in the injector's specimen production. Comprehensive performances were compared between the samples obtained by MIM technology and the traditional products with the method of simulation and experiment. Results show that,the new samples have larger advantage than traditional products at aspects of the electromagnetic performance, the dynamic response characteristics and the dynamic flow characteristics.

Key words: electronic gasoline injector, metal injection molding(MIM) technology, electromagnetic performance, dynamic response characteristic, flow performance
