Americká společnost Reg Technologies pracuje od roku 2003 na vývoji nového typu rotačního motoru nazývaného RadMax. Má jeden rotor, ježse otáčí mezi dvěma vačkami. Svislé elementy zavěšené na rotoru rozdělují prostor mezi ním a vačkami na dvanáct komor, do nichžse nasává směs. Stoupající profil vačky v další fázi zmenší objem komory a směs se kompresním teplem vznítí. Motor dosahuje zřejmě vysoké účinnosti pří malých rozměrech a hmotnosti.
RadMax - velmi nadějný a účinný "newankelovský" rotační motor
The RadMaxTM engine is an internal-combustion engine built around a rotary design. Reg Technologies, Inc. owns the worldwide rights to the RadMaxTM rotary technology and REGI U.S., Inc. owns the U.S. rights. A RadMaxTM engine would have two to three times the power and weigh half as much as a Wankel engine of the same size. Simplicity, power, and efficiency are key design priorities in the development of the RadMaxTM Engine, a truly revolutionary form of rotary power.
The engine is comprised of a disc-shaped rotor and driveshaft which turn the housing, or stator, which remains stationary. Up to 12 vanes mounted parallel to the shaft slide up and down along the outside of the rotor as they follow a track along the inside of the stator housing. Combustion chambers form between the rotor, stator walls and vanes, and their volumes change as the vanes move during rotation. Although the design could use only two vanes, the current version has 12, which generate 24 combustion events (intake, compression, ignition, exhaust) per rotation. This lets the engine generate 1hp/0.75 lb, as compared to a conventional internal-combustion engine's 1 hp/6 to 7 lb. The engine has a compression ratio of 20:1, which lets it burn a variety of fuels, including diesel. More and animation on: www.regtech.com
