Abstract:

This report describes the results of a Transportation Systems Center investigation conducted under Urban Mass Transportation Administration sponsorship, of the practicality of a flywheel/diesel hybrid power drive for urban transit bus propulsion. The program is based on the use of a systems approach to develop propulsion design concepts consistent with environmental, safety, operational, and economic objectives. A simulation model, developed in the program, was the major tool used in the investigation and is described in detail in the report. This model should be useful in further studies of flywheel/heat engine analyses for vehicle propulsion application over various drive cycles. The hybrid used continuously variable ratio transmissions (CVRT) and a control subsystem to optimize fuel consumption in an 'on-off' mode of engine operation. The system is projected to have a reduction in fuel consumption of at least 50% (in gallons per mile) below the diesel-alone fuel consumption for urban bus driving cycles having more than 4 stops per mile. Regenerative braking is used, contributing to fuel consumption improvement.
