Enhanced Efficiency of Otto and Diesel Cycles by Employing Spinning Gas and a Flywheel.

In conventional internal combustion engines gas spinning is either not used at all, or used only with the purpose of increasing turbulence and better fuel –air mixing.  In this method, rotation is used for energy storage, hence it allows the improvement of thermal cycle efficiency.  A flywheel is used to transfer the energy into rotation of the gas and extract it when needed.
