| 摘 要： | 在分析汽车发动机点火系统电磁干扰产生机理的基础上,对干扰抑制措施进行了研究.在所搭建的点火系统电磁兼容试验台架上,对部分抑制措施进行了试验验证.结果表明,采用阻值较大及阻尼电阻长度较长的火花塞、在点火线圈的初级和次级绕组间加入屏蔽层,以及采用滤波器等可有效提高汽车发动机点火系统的电磁兼容性能.

| Abstract: | Based on the analysis of the mechanism which gives rise to the automotive ignition system EMI,EMI suppression method is investigated.And we established the test bench to validate the EMI suppression method.The results show that selection of spark plug with bigger resistance and longer damping resistance length,and adding a shielding layer to the primary and secondary winding of ignition coil,and also adopting EMI filter can enhance EMC performance of the automotive ignition system effectively. |
