PROPULSION SYSTEMS STUDIES OF DUAL-MODE VEHICLES

Performance and fuel economy of the dual-mode vehicle was investigated by using three alternative propulsion methods: turbine electric, diesel electric, and diesel mechanical. The turbine and diesel electric vehicles are driven by a three-phase induction motor through a conventional rear axle. The diesel-mechanical propulsion engine provides the power for both on- and off-guideway operations. A computer model was used to predict vehicle performance. All three propulsion systems offer a satisfactory solution for both on-guideway and off-guideway propulsion requirements of the dual-mode vehicle. The diesel-mechanical propulsion, representing the low technology approach, provides a satisfactory solution for the propulsion requirements of the dual-mode system. Reliability and low pollution characteristics make the diesel engine the most accepted powerplant for transit coach operations. The hydromechanical transmission represents a significant advancement in transmission technology for heavy- duty vehicles. The lower system cost and familiarity with diesel engines could eliminate possible points of resistance to unconventional propulsion systems on the part of transit companies when the dual-mode transportation system is considered as one of the possible alternatives for improving their services.
