电控喷油器开启和落座滞后时间的研究

Research on the Opening and Closing Times of an Electromagnetic Injector

本文从电磁喷油器的结构和工作原理出发,分析了电磁喷油器的喷射过程,详细推导了喷油器针阀开启及落座滞后时间的数学表达式,并利用80C196单片机开发了电磁喷油器开启及落座滞后时间测试系统。

The injection process was analyzed based on the structure and the operation principle of an injector and the mathematical formula of the needle valve opening and closing lag times were deduced to instruct the performance improvement of the electro-manetic injectors in this paper.And a detecting system based on 80C196 microprocessor was developed to measure the opening and closing lag times of the electromagnetic injectors.
