Freedom's Rotapower engine has all the inherent advantages of existing Wankel-type rotary engines. In addition, it improves the Wankel-type engine performance as follows:
Emissions and fuel consumption
Uses our proprietary low cost lean burn combustion process together with our patented combustion surface coating and pre-heated incoming fuel-air charge to greatly reduce both emissions and fuel consumption. This technology has the potential to eliminate both the lubrication and cooling systems.
Long engine life in a low-cost design
Uses a new proprietary rotor and rotor cooling technology to reduce rotor weight and related mechanical stresses throughout the engine. Uses new apex seal material and proprietary design to allow replacement of the costly plasma sprayed internal coatings with inexpensive plated surfaces.
Maximum power with minimum weight and size
Uses our proprietary porting design and advanced component development to generate twice as much power for its weight as the popular two-stroke competitor.
Modular design allows low cost power growth
Uses proprietary design that allows additional rotor housings and rotors to be added with only a change in the length of assembly bolts.
Ability to operate on any fuel
Proprietary technology developed to lower emissions and fuel consumption also allows the use of any type fuel with only minor changes in the fuel injection system.
While all of the above advantages make the rotapower engine attractive, the ultimate advantage of this engine is its ability to generate only 4% of the emissions of a four-stroke engine and 1% of the emissions of a two-stroke piston engine
