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       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.

• 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
