Pistonless Rotary Engine - Pistonless Rotary Engines

Pistonless Rotary Engines

The basic concept of a (pistonless) rotary engine avoids the reciprocating motion of the piston with its inherent vibration and rotational-speed-related mechanical stress. As of 2006 the Wankel engine is the only successful pistonless rotary engine, but many similar concepts have been proposed and are under various stages of development. Examples of rotary engines include:

Production stage

• The Wankel engine
• The Atkinson cycle engine

Development stage

• The Baylin Engine
• The Engineair engine
• The Liquidpiston engine
• The Hamilton Walker engine
• The Quasiturbine
• The Ramgen Integrated Supersonic Component Engine
• The Rand cam engine
• The RKM engine (RotationsKolbenMaschine)
• The Sarich orbital engine
• The Tri-Dyne Engine
• The Trochilic engine
• The Wave disk engine
• The Moto Turbine Radiale by Jean Claude Lefeuvre
• The Jonova engine

Conceptual stage

• The Gerotor engine
• The Rotary Engine by Jose-Ignacio Martin-Artajo, SI
