ADIABATIC DIESEL ENGINEJUSTIFICATION AND PROGRESS

摘要

The work concerns on innovative, high-payoff engine called the Adiabatic Diesel Engine. This engine insulates the diesel combustion chamber with high temperature materials, including ceramics, to alloy; "hot" operation near an adiabatic operating condition. The "hot" or insulated high temperature components include piston, cylinder head, valves, cylinder liner and exhaust ports. Additional power and improved efficiency derived from this engine occur because thermal energy, normally lost to the cooling water and exhaust gas, is converted to useful power through the use of improved in-cylinder work and engine turbo-compounding. By greatly reducing lost energy and essentially eliminating the need for a conventional cooling system, this engine will dramatically improve fuel economy or increase power for the same fuel input by 30% over current highly efficient diesel engines, and will result in approximately a 40% reduction in both weight and volume for the same horsepower level. This writing provides general justification and a progress report for the Adiabatic Diesel Engine Program.
