The technology of the Willocx Engine with differential evaporation pressures

The "Willocx Engine" under the US patent number 10,851,733 (titled "Engine with Differential Evaporation Pressures") is a system generating mechanical energy by exploiting the thermodynamic differences between evaporation pressures where a liquid rapidly transitions into a gas and condenses back under varying temperatures. Willocx's design introduced a patented mechanism that accelerates the evaporation cycle, increasing power density dramatically. The engine is running below the water boiling temperature. By relying on liquid-vapor phase changes rather than gas expansion alone, this engine reduces the required temperature difference while boosting exponentially power density compared to standard Stirling or traditional external combustion engines.

Applying the standard temperature based on Carnot formula (ef = 1-(Tc/Th) severely misrepresents the real physical cycle inside the Willocx Engine. Temperature is not the primary driver of the pressure strokes. Instead, the pressure spikes are generated by mass transfer and phase transitions. Because a change of temperature does not produce a corresponding variation in vapor pressure inside the specific mechanical design, using the Carnot temperature formula yields completely inaccurate, near-zero efficiency results that don't match reality. The true measure of the efficiency = 1-(Qout/Qin) and is the only accurate and absolute formula to govern this engine based on energy quantities.

By shifting the focus to energy quantities (Q), the engine takes brilliant advantage of water's thermal capacity and latent properties. Water requires an immense amount of energy to change states without a massive shift of temperature. By mechanically controlling the vapor boundaries rather than forcing extreme heat cycles, the engine converts a high proportion of that phase-change energy (Qin) directly into mechanical work before it can be lost as waste ambient heat (Qout).
