Revolution Rotary Engines Inc.

The Evolution

Nearly 50 years of exciting development in the field of piston engines have passed since the development and successful test of the first rotary piston engine, the DKM54. The requirement of increasing power density, maximum reliability and life as well as decreasing emissions initiated the research and development of new technologies in all areas of engineering sciences. While in the past most efforts have been targeted towards optimizing the power to weight ratio and minimizing fuel consumption, the focus has changed to minimize harmful emissions, in particular when using lower quality fuels respectively accepting fuels with larger tolerances in composition.

The development and introduction of the improved theoretical models and computer models throughout all areas of engineering, such as aero-, gas- and thermodynamics as well as stress and life analysis for mechanically and thermally highly loaded components, resulted in engine designs pushing the technology ahead. New measurement technologies and improved test equipment enabling a better theoretical understanding of the physics become the starting point for new development methods. The introduction of electronic controls, for example, has enabled the development engineers to design the thermodynamic cycle in such a manner that the combustion process can be optimized throughout the whole operating envelope, including transient operating conditions, resulting in improvements to the operating and emission characteristics of the engine.

The new families of rotary engines currently under development represent the symbiosis of numerous high technologies which have resulted in reliable, environment-friendly and economic engines for a wide range of applications.

The largest manufacturer of Wankel rotary engines in the world is Mazda, who have produced over 3,000,000 cars with rotary engines.
