首先分析了点火系统电磁辐射干扰的机理，并通过实验发现，点火系统低压侧电源线上的共模电流是产生电磁辐射的主要来源，据此建立了点火系统电磁辐射发射的模型。继而在验证有限元法计算导线周围电磁场可行性的基础上，建立了整车点火系统电磁辐射发射的有限元模型，并进行仿真。仿真与实测结果表明，所建的整车点火系统电磁辐射发射模型可行有效。

Firstly, the mechanism of electromagnetic radiation ( EMR) interference of ignition system is an-alyzed and it is found by experiments that the common mode current on the power line in lower voltage side of igni-tion system is the main source of EMR emission. Based on this an emission model for the EMR of ignition system is established. Then after the feasibility of FEM in calculating the electromagnetic field around single wire is verified, the FE model for the EMR emission of vehicle ignition system is built and a simulation is conducted. The results of simulation and test show that the emission model established for the EMR of vehicle ignition system is feasible and effective.
