ULTRALIGHT GENERATOR ENGINES








Our mission is to unleash the full potential of autonomous applications by developing the lightest, most efficient, power-dense and vibration-free engines the world has ever seen.
At INNengine we strive to empower a new era of independence and reliability, providing these applications with the freedom to operate untethered from the grid: anywhere, anytime.
Choose freedom, choose INNengine.
INNengine signifies the most remarkable revolution in internal combustion engines since the inception of the Otto engine. Its revolutionary patented technology is a breakthrough in terms of weight and size-to-power ratio, as well as efficiency, all while being completely vibration-free! These qualities make it the ideal choice for an airborne range extender generator and a compelling solution for modern propulsion needs.

INNengine is 70% Smaller & lighter
A 700cc 120HP/244Nm engine weighs just 38kg
But there is more to it. The larger the displacement the bigger the difference because the size reduction is quadratic.
SPECIFIC POWERINNengine is the first one to introduce 1 Stroke technology, meaning our engines have 2 power events per revolution in every cylinder.
This allows them to deliver twice the power of a 2-Stroke and 4 times that of a 4-Stroke.

INNengine technology is the first one to offer a perfectly balanced engine with no counterbalancing measures required.
Having simple harmonic cinematic ensures perfect 1st and 2nd degree balance with 0 vibration.
At INNengine we have patented and developed two disruptive engine concepts: the e-REX and the REX-B.
Both e-REX and REX-B have INNengine patented 1Stroke engine technology. This means they have 4x more power events per revolution than a conventional 4Stroke and twice more than a 2S.

e-REXThe e-REX comes to replace conventional 4Stroke engines in all current applications and more. It’s state of the art technology lowers consumption&emissions compared to any modern 4Stroke engine while being 4x more powerful and compact.
After hundreds of hours of testing and having powered a demo car, our e-REX engine has achieved TRL6 and we are on track of achieving TRL9.
REX-BThe REX-B is a simplification of the e-REX only in concept but not in quality.
Built to satisfy aerospace industry standards, the REX-B will replace 2Stroke engines in those applications where raw power, simplicity, ultracompacity and cost are not just desirable but key.
Electric motors are cleaner and more efficient, liquid fuel and ICE are lighter, more power dense and provide autonomy/protection against hazards. The future demands taking the best of both worlds in a combined solution.
The future is eclectic, the future is INNengine.

INNengine is proud to announce that it is focusing its cutting-edge ultralight generator technology on the drone/UAV sector. With drones becoming increasingly critical for a wide range of applications, from aerial surveying to emergency response, the need for reliable and long-lasting power has never been greater.
By leveraging our ultralight generator technology, we can provide drones with a highly efficient and lightweight power source, enabling them to fly for hours instead of mere minutes. We believe that this technology will transform the drone industry, unlocking new capabilities and expanding the potential of this rapidly-evolving field.
