| Abstract: | automobile; difficult aspects in interference inside the design of modern the automobile, so the research on the calculation method of electromagnetic radiation caused by ignition system becomes a hotspot in the field of automobile electromagnetic compatibility nowadays. Through the derivation of the FDTD formula of Yee cell which contains resistance and the establishment of reasonable excitation source, the FDTD model of ignition system of certain type of car is established with the aid of AUTOCAD technique, and the electric field intensity inside the car caused by the high-voltage wire of ignition system is calculated. The work and the results can provide some references for the research of automotive electromagnetic compatibilitv. |
