With the introduction of the all-new Gemini uniflow diesel engine, Superior Air Parts continues its history as a leader in making sport and general aviation engines greener, more attainable and more affordable for pilots around the world.

Although the Gemini is a totally new engine, its two-opposing-pistons-per-cylinder design is actually based on the six-cylinder, 12-piston Junkers Jumo 205 engine. This was a well-established engine design that has been well proven through tens-of-thousands of hours aboard WWII era multi-engine German bombers and commercial aircraft.

Superior has taken the established concept of those engines and is working with a leading engine developer to improve on the basic design and create the new Gemini series diesel engines. And because it has been created for today’s aviation needs, Gemini’s unique design eliminates many of the drawbacks of current aircraft diesel engines.
