• Abstract:
  A flywheel/diesel hybrid power drive configuration for urban transit bus application is investigated using a computer simulation model. The hybrid uses continuously variable ratio transmissions and a control subsystem to optimize fuel consumption in an "on-off" mode of engine operation. The system is projected to use 50% less fuel than a diesel-alone in urban driving cycles having more than 4 stops per mile. Regenerative braking is used, contributing to fuel consumption improvement. The computer simulation model developed as a major tool for this investigation is described in detail.
