Rotapower Engine performance

Freedom Rotapower Engine
Performance Advantages

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 engine.
-Compares to 7 parts for 2-stroke and 25 parts for 4-stroke piston with same nstantaneous 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.

Proven multi-fuel performer
-Demonstrated on gasoline, natural gas, alcohol and propane
-Spark-ignited diesel, kerosine and jet fuel

Very low emissions levels
-See Emissions Performance

Enhanced energy at exhaust
-Exhaust temperatures > 1500 °F
-Acts like a naturally occuring thermal reactor
-Ideal for turbocharge/co-generation applications

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
