The purpose was to assess the practicality of a transmission for use in a heat engine/flywheel propulsion system to reduce emissions. The system was to be suitable for incorporation into a full size 'family car' automobile. The different possible link types (mechanical, hydrostatic, and hydromechanical) between the engine, flywheel, and vehicle wheels were analyzed. Many transmission schematics were investigated, and several combinations were selected for further evaluation resulting in the final recommended configuration. Controls were selected and analyzed using a digital dynamic simulation computer program and an analog computer simulation. System performance, stability and driveability were deterined. Cost estimates were made for the selected configuration using comparative data, vendor quotations and in-house estimates. Comparisons with a conventional three speed automatic transmission were made. A hydromechanical transmission configuration with interdependent links between the flywheel, engine, and wheels was the resultant selection. The flywheel/transmission was configured for a tran-axle installation, which was considered optimum. (Author)
