Research on EMC Performance and Optimization Technology of Engine Ignition System
鉴于发动机点火系统是车辆电磁干扰的主要来源，提出了优化其电磁兼容性能的方法。在分析点火系统电磁干扰产生机理的基础上，对各种电磁干扰抑制措施进行了理论研究。通过搭建点火系统电磁干扰试验台架，确定点火系统电磁干扰试验的点火信号和频率，对部分点火系统电磁干扰的抑制措施进行了试验验证。结果表明，适当提高火花塞内电阻阻值、加长内电阻体长度、采用带有EMC抑制电阻的点火线圈，可有效地提升点火系统的电磁兼容性能。
Considering that the engine ignition system is the main source of vehicle electromagnetic interference, a method to optimize its electromagnetic compatibility performance is proposed.On the basis of analyzing the mechanism of electromagnetic interference in the ignition system, theoretical research was conducted on various electromagnetic interference suppression measures.By building an electromagnetic interference test bench for the ignition system, the ignition signal and frequency of the electromagnetic interference test for the ignition system were determined, and some suppression measures for electromagnetic interference in the ignition system were verified.The results show that the EMC performance of the ignition system can be effectively improved by properly increasing the resistance value in the spark plug, lengthening the length of the internal resistance body, and adopting the ignition coil with EMC suppression resistance.
