Title: Otto and diesel cycles employing spinning gas

Abstract

An internal combustion engine is disclosed and includes a main cylinder and main piston that are relatively axially displaceable along a main axis to define a variable volume main working chamber. At least one valve is configured to admit air and fuel into the working chamber forming an air/fuel mixture. The main cylinder is configured to cause the air/fuel mixture in the main cylinder to spin rapidly enough to cause a substantive change in the heat capacity of the air/fuel mixture creating a spinning air/fuel mixture. The main cylinder and main piston are configured to compress the spinning air/fuel mixture to create an ignitable spinning air/fuel mixture. The spinning air/fuel mixture is ignited and the main cylinder and main piston are configured to extract mechanical energy from the ignited spinning air/fuel mixture. An exhaust valve is configured to exhaust combustion products from the main working chamber.
