TECHNOLOGY
A New Kind of Engine
Our engine is built on pioneering research from Stanford University’s GCEP program and has been developed and refined by our senior team over more than a decade.
Led by Dr. Chris Edwards, the Stanford team demonstrated—theoretically and experimentally—that Extreme State Engines could reach 60% efficiency in a single thermodynamic cycle, and up to 70% when combined with a secondary energy recovery cycle.
This breakthrough laid the foundation for the ultra-efficient engine technology we developed, which is based in two principles: Minimize Exergy Destruction and Maximize Work Extraction. Let’s see how we implement it.
Minimizing Exergy Destruction
Threshold Combustion
We use a unique Quasi Detonation combustion to achieve the highest possible gas pressure in the combustion chamber, without the losses of supersonic shockwaves.
Normal diesel and gasoline engines have combustion flame speeds of around 20-30 m/s, while our Quasi Detonation combustion has speeds between 900-1000 m/s, very, very fast, but still lower than a full detonation speed of 1800 m/s.
That speed allows us to achieve 100% fuel burn in less than 300 microseconds, one order of magnitude faster than legacy engines.
In that time window, our new design has no volume variation, making it the only Constant Volume Combustion thermodynamic cycle engine, the most efficient possible.
We use AI to control high energy plasma ignition, 100x more powerful than an ordinary spark engine, in highly turbulent, homogeneous, premixed air fuel.
Using simple molecules of hydrogen, methane, methanol or ethanol, there is very little exergy destruction in combustion and virtually no pollutants, only water and CO2. The reaction occurs too fast for NOx formation.
Full Adiabatic Engine
Our engine has all parts coated with nano technology heat barrier, which combined with ultra-fast combustion and gas expansion (around 2 milliseconds), has the lowest possible heat loss.
Superlubricity
Until now, superlubricity, or friction coefficient lower than 0,01, was a phenomenon on tribometers at lab scale. We have the first engine designed for it. Our nano coatings and especially formulated oils work very differently from conventional hydrodynamic lubrication.
Integrated Cycle Engine
Until now we have single cycle engines, the vast majority of installed base with efficiencies as low as 20%, a few combined cycle, very large power plants up to GW, where a gas turbine works with a second engine, a steam turbine, to get up to 60% efficiency.
Historically, we tried a compound cycle, where a turbine is attached to a piston engine to recover energy from exhaust and add torque to engine shaft. Very limited engines were built, with result efficiencies close to 40%.
We invented the Integrated Cycle Engine with three work extraction devices in the same shaft, the first of a kind, where all three stages are tuned in synch for maximum efficiency up to 70%.
All variables, air mass, fuel fraction, steady and pulsed flows, ignition energy, gas temperature and speed are synergistically adjusted in real time by AI, to maximize efficiency in dynamic ambience (air temperature, pressure and humidity) and use scenarios (RPM and Load).
