High temperature insulating material for new engine concept

Click For Summary
SUMMARY

The discussion centers on a novel engine design that incorporates combustion within a moving piston traveling in a circular arc, significantly reducing abrasion and vibration issues associated with traditional reciprocating engines. The objective is to apply high-temperature thermal insulating materials to the interior of the rotating combustion chamber and the exhaust cylinder to minimize heat loss and enhance efficiency. The engine will operate on various fuels, including biofuels, gasoline, diesel, and natural gas, aiming to eliminate the need for cooling systems. This innovative approach is expected to maintain high pressures and temperatures until the gases are released for torque production.

PREREQUISITES
  • Understanding of thermal insulating materials, specifically ceramics
  • Knowledge of engine design principles, particularly circular piston mechanisms
  • Familiarity with combustion processes in internal combustion engines
  • Experience with simulation tools for material testing and performance analysis
NEXT STEPS
  • Research high-temperature ceramic materials suitable for engine applications
  • Explore simulation software for testing thermal insulation performance
  • Investigate the effects of various fuels on combustion efficiency in innovative engine designs
  • Study the principles of torque production in circular piston engines
USEFUL FOR

Engine designers, materials scientists, automotive engineers, and researchers focused on improving engine efficiency and thermal management.

In the past, reciprocating engine platforms have prevented the use of thermal insulating materials like ceramics due to, among other reasons, abrasion and vibration. One of the problems in the past has been the movement of the piston and piston rings over the cylinder wall where the insulating materials had been attached.

We have a new engine design that places combustion inside a moving piston that travels in a circular arc. Because of the new structure of this engine, the inside combustion chamber is practically free from abrasion and vibration, however, it will be subject to very high pressures and temperatures. We would like to coat the inside wall of the rotating combustion chamber with a thermal insulating material. The environment will be exposed to a wide range of fuels including bio fuels, gasoline, diesel, and natural gas.

Here is a video that will help aid understanding of what we are trying to accomplish. Compression and combustion are two of the phases of the four cycle process that occur within the rotating piston shown on the video. The objective for the insulating material is to keep temperatures and, by extension, pressures high within the rotating piston until the critical moment when the gases are released to produce torque. The hope is that we will allow as little heat loss to the piston wall as possible. The second goal is to coat the cylinder that the piston will exhaust the combustion products into. If we are able to reduce heat absorption in these two areas, we project that the engine will eliminate the need for cooling and gain efficiency.

Anyone researching this area of study?

Thank you very much,

Randy

Hi Randy, quite similar problem addressed with the guys from blue energy. You got to try to run on simulation and try different materials.
