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 and increases the pressure-to-volume ratio, a unique feature responsible for new design gains.
The RME reduces the acceleration exposure magnitude through a power stroke, resulting in an immediate fuel saving associated with an increase in work time of a power stroke.
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 main engineering design question of the RME is, how to understand and evaluate moving-boundary systems. This question led to the development of a simplified open-system framework of the motion geometry and time-dependent acceleration exposure.
This framework was presented as a design method for systems with moving geometry, 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 started 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.
The Physics of Time for Engineers is currently published and available for more in depth analysis.
Third-Party Validation
The current project presentation cites third-party and development milestones, including:
· ARAI India CONVERGE CFD (2023–2025): reported +40.6% indicated work at identical trapped air and fuel,
· a 2025 granted patent addressing historical lubrication and breathing issues,
· and stated scalability to both diesel and gasoline platforms with variable compression ratios.
