Solaroli claims to hold a breakthrough patent on a "pseudo
adiabatic engine" that is more than twice as efficient as conventional engine technology.
"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.
An
adiabatic engine, by definition, is an engine in which no heat is added or subtracted during a thermodynamic cycle.
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.
