In this article, we use an extended hybrid multitransmission line (MTL)/method of moments (MoM) approach for analyzing the diesel common-rail distribution system model installed in a perfect electrically conductive automotive vehicle and its interaction with an EMC wideband antenna in the 20–200 MHz frequency band. The proposed workflow involves analyzing the impedance of a discontinuity, such as changes in geometry or materials, in the cable system using a full-wave MoM solver. The impedance is then included in the MTL circuit model by introducing lumped element impedance at the boundary between different regions of the cable system. The extended hybrid MTL/MoM approach has higher accuracy and better predicts the EMC behavior of the system. Its accuracy, efficiency, and flexibility make it a promising solution for future automotive EMC challenges.
