Doesn't have anything todo with drag racing but interesting none the less.
I recently came across Elastic pistons, never heard of an elastic piston before. The piston is divided into two parts. The crown and the section the part that connects to the piston pin. The two parts are moving relatively to each other using a Belleville-type spring which stores dynamic energy at the of the ignition process where the connecting rod is in such a position (almost perpendicular to the horizontal plane) that we cannot gain any big amounts or torque. When the inclination of the conrod grows, then the spring gives its dynamic energy to the system. And this is the time when we want to have more energy, right?
Ford's Elastic Piston
This system should have some interesting effects on the thermodynamic cycle. It would instantly reduce the effective compression ratio at the time of detonation if the spring tension was set appropriately. Cylinder mass would obviously go up. It certanily isn't new, but I wondered if any prototypes have been built? and why they arn't used today?
