Not Just an Upgrade — A Rethink
Most players in the market—whether offering conventional gensets or newer fuel-cell and battery systems—are adapting legacy architectures for cleaner fuels. Even so-called “hydrogen-ready” engines often rely on designs originally optimized for fossil combustion, like piston or turbine systems.
At Isochor Engines™, we believe that incremental upgrades can’t deliver the step-change in efficiency and performance the energy transition demands. That’s why we started from first principles.
Our pulse-to-rotary platform achieves true pressure-gain combustion and high mechanical efficiency in a compact, modular form—purpose-built for hydrogen, e-methane, ammonia, and biogas.
We’re not retrofitting the past—we’re engineering the future: systems optimized from the ground up for zero-carbon performance.
IsochorEngine™ Platform
IsochorEngine™ is our core pressure-gain combustion platform, engineered to deliver a step-change in efficiency through two key mechanical breakthroughs:
True Pressure-Gain Combustion: Unlike conventional constant-pressure or piston-based systems, IsochorEngine™ maintains a fully sealed combustion chamber during ignition.
This enables near-constant-volume combustion, allowing maximum pressure recovery and exceptional thermal efficiency — the foundation of true pressure-gain energy conversion.Amplified Angular Displacement and Torque: A novel lever-based architecture transforms discrete pressure pulses into smooth, continuous rotary motion.
This geometry amplifies both angular displacement and torque output beyond the limits of conventional engines or turbines, unlocking compact, high-efficiency performance in a scalable form factor.
By overcoming the inherent inefficiencies of traditional combustion systems, IsochorEngine™ provides a modular, fuel-flexible foundation for next-generation energy solutions — from distributed generation and industrial power to clean propulsion applications.
It’s not just an improved engine design — it’s a new thermodynamic architecture for the zero-carbon energy transition.
Ultra-Efficient Performance
IsochorEngine™ achieves up to twice the efficiency of conventional combustion systems through true pressure-gain thermodynamics and optimized energy conversion.
Key Advantages
Dramatically lower fuel consumption, reducing both cost and emissions.
Reduced carbon footprint, even when operating on conventional fuels.
Extended range and endurance, enabling efficient use of low-energy-density renewable fuels such as hydrogen or ammonia.
Multi-Fuel Flexibility
Engineered for versatility, IsochorEngine™ operates seamlessly across a wide spectrum of fuels — from today’s natural gas and propane to tomorrow’s green hydrogen, ammonia, and synthetic e-fuels.
Fuel Flexibility Benefits
Compatible with existing fossil fuels for near-term deployment.
Ready for renewable fuels including hydrogen and ammonia.
Supports fuel blending (e.g., hydrogen–natural gas mixtures).
Enables a smooth transition to zero-carbon fuels without requiring new infrastructure.
IsochorEngine™-Gen
As renewable electricity grows, so does the need for clean, resilient off-grid power. Conventional generators still rely on fossil fuels, undermining decarbonization efforts.
IsochorEngine™-Gen is powered by our Pulse-to-Rotary Generator Platform (PRGP) — a breakthrough architecture that converts pressure pulses into smooth rotary power with true pressure-gain efficiency.
Fuel-flexible and highly efficient, IsochorEngine™-Gen delivers zero-carbon-ready backup power for remote, industrial, and critical applications — operating on hydrogen, ammonia, or blended fuels without new infrastructure.
