About Us

Rotodyne Engine Development, LLC is an intellectual property holding company for technology related to the revolutionary Rotodyne Engine with the goal of selling and/or licensing rights to extended piston dwell and constant volume combustion. It is the brainchild of entrepreneur and former patent attorney Larry Chasin and renowned sculptor and renaissance man, Doug Johns whose 3-dimensional perception sparked the flash of genius that resulted in the discovery of the engine variables that would allow de-coupling of the piston motion from the crank angle and thereby enable constant volume combustion to take place in a re-invention of a traditional barrel-type Internal combustion engine.

Rotodyne Engine Development is now executing a distributed engine development strategy to partner with independent engine builder(s) to build and test a prototype of the revolutionary Rotodyne Engine, in order to then sell and/or license the technology under US Patent 7,677,210, which is the pioneering patent for constant volume combustion. All engine builder participants will receive a share of the profits and proceeds from all sales and licensing.
