Freedom Rotapower Engine
- High power to weight ratio
- More than 2 HP per pound of installed
weight in high-performance versions
- Compares with .6 HP/lb. to 1 HP/lb. for
2-strokes and .3 HP/lb. to .65 HP/lb. for 4-stroke pistons.
- High power to volume ratio
- (Power Output / Volume) > 100 HP per
cubic foot of installed volume
- Compares with 36 HP/ft³ to 50 HP/ft³
for 2-strokes and 10 HP/ft³ to 20 HP/ft³ for 4-stroke piston engines.
- Few moving parts
- Moving Parts - only 2 for single rotor
- Compares to 7 parts for 2-stroke and 25
parts for 4-stroke piston with same instantaneous output torque.
- Solid fuel economy
- Specific Fuel Consumption < .45
lb./HP-hr ~ (stratified charge). Expect <.4 lb./HP-hr when both
stratified charged and turbo-charged
- Compares to .65 lb./HP-hr for 2-strokes
and ~ .4 lb/HP-hr for the best 4-stroke piston.
- Demonstrated on gasoline, natural gas,
alcohol and propane
- Spark-ignited diesel, kerosine and jet
- Very low emissions levels
- Enhanced energy at exhaust
- Exhaust temperatures > 1500 °F
- Acts like a naturally occuring thermal
- Ideal for turbocharge/co-generation
- Low vibration levels
- Hard mounted engine can be used as part
of the structure
- Modular design
- Stacking of rotors easily extends range
of available power
- Patented intake and porting arrangement increases
power by 50% verses OMC rotary engine of the same displacement.
- Low cost patented approach to insulating the
rotor bearing from the rotor.
- Proprietary tip seals and rotor housing coating
provides projected seal life of over 10,000 hours.
- Tuned intake and exhaust system to achieve over
100% volumetric efficiency (using SuperTrapp technology).
- Patented composite coating has the following
- Lowers specific fuel consumption by
- Reduces rotor housing cooling load by
- Reduces rotor cooling air requirements
by over 40%.
- Reduces emissions to near zero with
- Provides solid lubrication at very
elevated temperatures (600° F)
- State-of-the-art fuel injection system.
- Operated Freedom Motors developed engines on diesel,
alcohol and kerosene as fuels.
Patented lubrication system eliminates either mixing oil with fuel
(OMC), or injecting oil into incoming air stream (Mazda).
