High temperature insulating material for new engine concept

In summary, the use of thermal insulating materials in reciprocating engine platforms has been limited due to abrasion and vibration. However, a new engine design with combustion inside a moving piston may allow for the use of such materials. The goal is to keep temperatures and pressures high within the rotating piston, and potentially eliminate the need for cooling and increase efficiency. Further research is being conducted in this area, including simulations with different materials.

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.
 

1. What is high temperature insulating material?

High temperature insulating material is a type of material that is able to withstand extreme heat without melting or degrading. It is commonly used in industries such as aerospace and automotive for applications where high temperatures are present, such as in engines.

2. What are the benefits of using high temperature insulating material in a new engine concept?

Using high temperature insulating material in a new engine concept can provide several benefits. It can increase the efficiency of the engine by reducing heat loss, improve engine performance, and extend the lifespan of the engine by protecting it from extreme temperatures.

3. What types of high temperature insulating material are commonly used in new engine concepts?

Some commonly used high temperature insulating materials in new engine concepts include ceramic materials, such as ceramic fiber and ceramic coatings, as well as metallic materials like titanium and nickel alloys. Each of these materials has unique properties that make them suitable for use in high temperature environments.

4. How does high temperature insulating material help reduce emissions in engines?

High temperature insulating material can help reduce emissions in engines by improving the combustion process. By reducing heat loss, the engine can operate at higher temperatures, which can lead to more efficient and complete combustion of fuel. This results in fewer emissions being produced.

5. Are there any drawbacks to using high temperature insulating material in new engine concepts?

While high temperature insulating material can provide many benefits, there are some potential drawbacks. These materials can be expensive and may require special manufacturing techniques, which can increase the overall cost of the engine. Additionally, some materials may not be suitable for all engine designs and may require additional testing and research to ensure compatibility.
