History
Anyoon Rotary Engine has been in development for 6 years, originally designed in India and advanced by Dr Diji Jayakaran, it is now being further developed in Europe by its inventor with the SME SUM S.R.L.S., which acquired the exclusive license and owns the technology since 2014. Dr Jayakaran was offered by SUM the opportunity to complete the engine prototyping and qualification test in Europe, leveraging SUM’ specialist competence in complex CAD design and modelling and their partnership already in place with the precision mechanics manufacturer CECOM.
SUM has further elaborated and optimised the engine design: the two companies performed various simulations using a virtual model technology: established a model of the mechanical system, adopted both the bottom-up and top-down assembly model, completed the virtual assembly, simulated 3D system movements and the dynamic characteristics and delivered a static analysis under realistic environment. The result was a simplified design and development process, able to shorten development cycles and to be transferred back and implemented into a physical prototype.
A prototype of the Anyoon engine was built and run in a test powertrain, the demonstration results showed that a remarkable thermal efficiency can be achieved by the Anyoon engine if it can be manufactured with good sealing between volumes. The thermal efficiency of Anyoon has been found much higher than in current automotive reciprocating engines – 35-38% for gasoline and 40-45% for diesel. The new rotary design and thermodynamic cycle are highly effective, 51% efficiency, 70% less moving parts, 50% more powerful than the average gasoline engine.
