Tour, and his team, successfully designed and built an operating split-cycle TourEngine™ prototype. Together with a positive feasibility report from one of the leading provider of engineering services to the world's automotive industry, and positive results from two independent thermodynamic studies conducted by consultants out of academia and a leading US national laboratory, and verified by a third independent thermodynamic study by a team at a major OEM, Tour Engine is focusing on developing and testing the next generation of prototypes. Utilizing existing relationships with leading academic institutions and personnel and working on establishing joint development projects with several major OEMs, we will rapidly produce a fully tested prototype that demonstrates the leap in efficiency, reduction in harmful emissions, and potential applications to the current internal combustion market. Our Simple approach, to design the TourEngine™ based on standard cylinder/piston technology, will allow manufacturers a relatively easy transition into production.
