Design of a 1 kW class gamma type Stirling engine

A study of the design of a kinematic drive gamma-type Stirling engine is reported. This heat engine is in the 1 kW class and was conceived for a portable electric generator. The peculiarity of this heat engine is its basic use of components taken from the line production, all of which are simple in terms of material and manufacture. The engine targets are defined in compatibility with the elements taken from a large scale production compressor and then new components like the heat exchangers and the crank mechanism are designed. Two pre-tests are effected: one to define the performances of the induction motor in the electric regenerative mode; and the other running the machine as a refrigerator
