Title: Enhanced Efficiency of Internal Combustion Engines By Employing Spinning Gas

Technical Report ·
DOI:https://doi.org/10.2172/1129012· OSTI ID:1129012

The efficiency of the internal combustion engine might be enhanced by employing spinning gas. A gas spinning at near sonic velocities has an effectively higher heat capacity, which allows practical fuel cycles, which are far from the Carnot efficiency, to approach more closely the Carnot efficiency. A gain in fuel efficiency of several percent is shown to be theoretically possible for the Otto and Diesel cycles. The use of a flywheel, in principle, could produce even greater increases in the efficiency.
