The company was started at a time when there was a great deal of hype surrounding ceramics, when designers were dreaming of the adiabatic engine running at a very high temperature that would cause the oil to break down," says Klatt.

Ceramics build better bearings

This is because a truly adiabatic engine with zero heat loss is not possible (due to thermodynamic constraints), but a 50 percent to 60 percent reduction in heat loss can be achieved.

This also suggests the direction of further development of an optimally adiabatic engine (compared to previous all-ceramic combustion systems) having the potential for additional thermal efficiency improvement.
