- "Adiabatic" is the correct term. It refers to a thermodynamic
- assumption that the heat engine process has no external transfer
- of heat. It is not really achieved in a real system, but
- efficiency is gained if heat losses to a cooling system are
- minimized. Modern engine technologies include the use of ceramics
- and other low thermal conductivity (ie space shuttle tile-ish)
- materials to contain the heat in the combustion gases, thereby
- reducing the need for large cooling systems and increasing fuel
- economy.
