The Thermobile Nitinol Engine

By using the stress-strain curves associated with Nitinol, both at T_O (over its martensitic transition) and T_U (under its martensitic transition), the principle of working mechanism for Nitinol Thermobile engine is analyzed.

Semiempirical calculation of the thermobile engine-efficiency show the efficiency to be dependent on the amount of strain imposed. An improved Thermobile engine which may prove ultimately suited for commercial application is introduced.
