Rotary Engine Design

Since 1975, we have evaluated, designed, developed and/or tested many components and complete propulsion systems for NASA, McDonald Douglas/Boeing, Mazda, NASCAR, IMSA and Grand Am, just to name a few. These efforts include many forms of piston, turbine and rotary engines and advanced rocket technologies.

In the Wankel rotary engine realm, we have evaluated and developed advanced systems and components to improve the performance, fuel economy and longevity of this engine for a variety of applications, including power generation and transportation vehicles such as automotive, motorcycles, marine and unmanned aerial vehicles (UAV).

Micro Wankel Engine Performance Enhancements

The major issues with the Wankel based rotary engine from the beginning were the longevity of the apex lip seal, the reduction of the noise level from the exhaust, achieving an optimum balance between engine cooling and structural requirements and the effect of these issues on its performance, exhaust emissions and fuel economy.

I-Rotary has solved these problems with the introduction of the Iannetti Apex Seal (IAS) in the early 1990s and the development of our proprietary noise reduction technology, the I-NRD, for various engine sizes and architectures.

I-Rotary has also developed proprietary solutions to improve the environmental footprint of the engine beyond present standards. These proprietary solutions reduce fuel consumption and emissions while simultaneously increasing the power to weight ratio, cooling efficiency, structural integrity and reliability of the rotary engine.

Future I-Rotary engines will be a superior and more practical alternative to other engines platforms which are currently available or being proposed.
