ADVANCED PROPULSION SYSTEM CONCEPT FOR HYBRID VEHICLES

The results of a nine-month study to identify and evaluate advanced propulsion systems for on-the-road hybrid vehicles are presented. Two concepts, both utilizing Stirling engines, were evaluated for five of reference mission/vehicles ranging from a two-passenger commuter car to a large bus, each had its own performance specification. Selection of the best hybrid configuration and reference mission/vehicle was made against these requirements, as well as the major goals of reducing petroleum consumption and minimizing total energy consumption. Both parallel and series hybrid systems, utilizing kinematic and free-piston Stirling engines, respectively, were evaluated. Detailed discussion, results and conclusions of the initial parametric studies, the trade-off evaluations, the life-cycle cost studies and the conceptual design definition are presented.
