An energy storage device is provided for a combustion chamber of an internal combustion engine. The energy storage device includes first and second end connectors connected to respective ones of a piston and crankshaft, and a flexible connection rod portion rotatably connected with the first and second end connectors. The flexible connection rod portion elastically buckles above a predetermined cylinder pressure threshold to store combustion energy and provide a more constant pressure combustion process.
