Revolutionary Design. Evolutionary Performance.
Since the mid-1960’s, Superior Air Parts has built a legacy as a leader in making general aviation engines greener, more attainable and more affordable.
Now, with the development of the Gemini Diesel we are bringing that same commitment to innovation to a new-generation of greener, more flexible and more economical engines.
Gemini’s unique two-opposed-pistons-per-cylinder design offers a number of advantages over current diesel designs including:
- Smaller size for greater installation flexibility
- High power-to-weight ratio
- Mechanically simpler design with fewer moving parts
- Highly-efficient two-stroke operation
- Green operation with much lower emissions
- Runs on available Jet A, diesel or bio-diesel fuels
- Up to 20% lower fuel burn than avgas-burning piston engines
- Retrofittable with many current piston engine designs
- Horsepower ranging from 80 to 550*
