The free-piston engine was first proposed by R.P. Pescara [1] and the original application was a single piston air compressor.

Free-piston air compressors were used, among others by, the German Navy. They were efficienct, compact and quiet. [2].


Several of free-piston gas generators were created, and these were in widely used in large-scale applications such as stationary and marine powerplants [3].
