UNCOOLED, UNLUBRICATED DIESEL?

Development of high-performance ceramics may improve thermal efficiencies of Otto, Diesel, Brayton, and Stirling cycles by increasing allowable operating temperatures, reducing heat losses, and recovering exhaust energy. If current research and development programs are successful, a possibility of an uncooled diesel engine of high thermal efficiency in conjunction with turbocompounding may exist. Future improvements such as the minimum-friction unlubricated engine may be made possible with high-performance ceramics. However, high-performance ceramics still have problems that have to be solved before they meet the requirements necessary for application and commercialization of heat engine concepts.
