A ground-breaking rotary engine technology, changing the way we look at combustion engines. The engine of the future.
"It was always meant to work that way."
The four-stroke internal combustion engine (ICE) is a 150-year-old design that, despite incremental improvements, faces significant problems that render it increasingly ineffective for modern demands.
Four-stroke ICEs are inherently heavy due to their complex construction, including cast-iron or aluminum blocks, multiple pistons, and ancillary systems (cooling, exhaust).
Four-stroke ICEs have hundreds of moving parts—pistons, valves, camshafts, timing belts, etc.—making them mechanically complex and prone to failure.
Four-stroke ICEs have low thermal efficiency, converting only 35-40% (gasoline) or 45% (diesel) of fuel energy into mechanical work, with the rest lost as heat.
Four-stroke ICEs generate significant noise from combustion, piston movement, and exhaust, typically 70-90 dB for cars and 100+ dB for trucks.
The NEX Engine represents a fundamental reimagining of combustion engine design, eliminating the limitations of traditional four-stroke engines.
Every element performs rotary motion, minimizing inertia, vibrations, and weight for smoother, quieter operation.
Simplifies design, reduces parts count, and enhances reliability, unlike complex four-stroke ICEs.
Easily adjustable for high efficiency or performance, ideal for diverse applications from drones to tanks.
Delivers 400% more power per revolution compared to piston engines of similar weight, maximizing performance.
Seamlessly operates on diesel, petrol, or hydrogen, aligning with global decarbonization trends.
Reduced friction boosts thermal efficiency (over 30% more efficient than traditional ICEs), cutting fuel use and emissions.
