REGI US, Inc. and Reg Technologies Inc. have completed a final set of manufacturing drawings for the RadMax Diesel Engine, and have released them competitive bid.
The companies are developing an improved axial vane type rotary engine known as the RadMax. The RadMax design was mainly developed by Radian Milparts and assigned to REGI US, Inc. in December 2005. (Earlier post.) The RadMax engine has only two unique moving parts, the vanes (up to 12) and the rotor; the design makes it possible to produce up to 24 continuous power impulses per one rotation that is vibration-free and extremely quiet.
The engine comprises 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.
The engine has a compression ratio of 20:1, which lets it burn a variety of fuels, including diesel. REGI US, Inc. and its parent company, Reg Technologies Inc., have built and tested a RadMax pump application for demonstration purposes (earlier post) and are currently designing and testing the RadMax diesel for a Fortune 1000 Company intended for aviation, automotive, industrial processes and military applications.
The drawing baseline incorporates the following features:
The new improved RadMax Diesel Engine design has incorporated solutions for vane actuation, cooling, and lubrication. The new vane actuator assembly reduces weight and friction, and the vane actuator design does not require any return springs. The Cam incorporates a water-cooling system, and the seal lubrication design has been completed. All designs have been incrementally reviewed by the REGI US, Inc. and the Fortune 1000 company engineers.
Extensive computer modeling with COSMOS has produced a lower-weight, higher-strength design. The modeling has lead to an implementation that significantly reduces centripetal forces between the vanes and the seals.
With this approved design, the test program will start shortly after receipt of the RadMax parts and assemblies. The tests will initially validate seal performance, vane actuation, pressurization, and lubrication. A series of tests will verify other technology areas, already proven by extensive analysis.
Fabrication of the new diesel engine parts is now underway and a comprehensive testing program will immediately follow. The goal is to license the technology to interested end users for several different applications.
