Heat-Engine/Mechanical-Energy-Storage Hybrid Propulsion Systems for Vehicles.

摘要

An analytical study indicated that a flywheel-only propulsion system could satisfy the performance requirements specified by the Office of Air Programs,Environmental Protection Agency,for a city bus,and that flywheel/heat engine hybrids could meet the requirements for cars,vans,and buses. In all cases substantial emission-free ranges could be achieved with hybrid systems by using the engine only periodically (at constant load) to recharge a large,high-energy flywheel. Experiments verified the principle of the 'superflywheel'by spin tests of unidirectional materials in rod or bar rotor configurations. (Author)
