High temperature insulating material for new engine concept

  1. Jan 24, 2016 #1
    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

    Thanks for the post! This is an automated courtesy bump. Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?

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