The Relative Motion Engine (RME) is a combustion architecture in which two pistons reciprocate in the same direction during combustion, forming a moving-boundary open-system platform. This geometry reshapes the pressure field during the power stroke and is intended to improve how combustion pressure is converted into useful work.
Conventional engines lose part of their available output through piston acceleration demands, thermal loss, and fixed-boundary limitations. In the RME approach, patented moving geometry changes the realization pathway of pressure during motion, allowing more of the same fuel energy to appear as useful mechanical output while remaining fully conservative.
The current project presentation reports CFD results showing peak pressures of approximately 180 bar versus 90 bar in comparable conventional cylinders, with reported gains of roughly 18–45% more brake work from the same fuel. The project presents these gains as the result of moving internal boundaries that reshape how pressure acts on the piston, without introducing any violation of established physical laws.
A Practical Engine — Backed by a Broader Method
The engineering challenge behind the RME was not only how to create motion, but how to understand and evaluate moving-boundary systems earlier and more effectively during design. That need led to the development of a simplified open-system diagnostic for analyzing how geometry, force transmission, participating mass, and time-dependent exposure interact during motion.
This framework does not replace classical mechanics. It is presented as a companion engineering method for systems with moving geometry — a way to make realization pathways more visible before full simulation and post-analysis are complete.
From the Engine to the Physics of Time
The Relative Motion Engine arose from a broader research program exploring:
· moving-boundary thermodynamics,
· geometry-shaped force and pressure realization,
· and open-system mechanics.
From that work emerged the Physics of Time (PoT): a time-primary engineering and diagnostic framework for open systems, evolving geometry, and structured realization. PoT is presented here not as a replacement for established laws, but as a broader framework for understanding how geometry and timing govern the way power and motion are realized.
