Abstract: Among conventional propulsion systems, the diesel propulsion system is very efficient in terms of fuel economy. However, conventional diesel propulsion systems have to meet aggressive fuel economy and stringent emission regulations. Electrification of the diesel propulsion system can play a major role in achieving future fuel economy and emission standards. In this paper, diesel hybrid propulsion system architectures are presented that could potentially meet future fuel economy and emissions compliance standards for a given set of performance criteria. Three diesel hybrid electric vehicle (D-HEV) architectures; parallel hybrid (PH), power split (PS) and series hybrid (SH) are investigated and analyses of these architectures are conducted. These architectures are compared and evaluated considering trade-offs between fuel economy and emissions targets.
