Goal

Create a very compact, high-power rotary engine inspired by a Mayan glyph that can operate on combustion, compressed air or steam.

Problem

Need for a high-power-density, low-vibration engine that can replace conventional piston engines and reduce emissions.

Concept Summary

The Maya Motor uses two mutually penetrating inclined planes of rotation that share a common centre point. The inclined rotary plate and the conical rotor members form variable-volume chambers whose expansion and compression generate torque. The device can be powered by combustion, compressed air or steam.

Detailed Description

The engine consists of a hollow cylindrical housing, a main shaft, a rotary plate inclined to the shaft, and two conical rotor members linked by partition walls. As the rotor-plate assembly rotates, the geometry creates continuously changing chamber volumes that draw in a working fluid, compress it, and release power. The design claims vibration-free operation and a very high power-to-size ratio.

Principles

  • Variable-volume chambers
  • Inclined rotating planes
  • Rotary combustion
  • Compressed-air actuation
  • Steam actuation

Scientific Domains

Mechanical Engineering Thermodynamics Fluid Mechanics

Mechanisms of Action

  • Pressure differentials in rotating chambers produce torque
  • Expansion and compression of working fluid within variable chambers

Energy Sources

Combustion fuel Compressed air Steam

Applications

  • Vehicle propulsion
  • Portable power generation
  • Hydraulic or pneumatic pumps

Claimed Performance

480 hp from a 40 cm^3 engine at 500 rpm and 10 atm pressure (vs. ~200 hp for a conventional engine of the same size).

Experimental Evidence

The article states that "self-critical tests by professionals large industrial companies, such as the Tyrolean company Swarovski Optik KG, was held" and that "calculations by experts have shown that the developed combustion engine at a size of 40 cubic centimeters and an operating pressure of 10 atmospheres already at 500 rpm with a performance of more than 480 hp emits." No quantitative test data are provided.

Replication Status

No independent replication or commercial production reported.

Limitations

  • No peer-reviewed data or independent testing
  • Claims of performance far exceeding conventional engines
  • Potential sealing and wear issues in rotating chambers

Red Flags

  • Unsubstantiated performance claims
  • Alleged suppression by multinational lobbies without evidence
  • Lack of detailed technical specifications or test results
