The free-piston engine linear generators can be divided in 3 subsystems: [1] [2] One (or more) reaction section with a single or two opposite pistons; One (or more) linear electric generator, which is composed of a static part (the stator) and a moving part (the magnets) connected to the connection rod.
Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).
While the invention of the basic free piston Stirling engine is generally attributed to Beale, independent inventions of similar types of engines were made by E.H. Cooke-Yarborough and C. West at the Harwell Laboratories of the UK AERE. [60] G.M. Benson also made important early contributions and patented many novel free-piston configurations ...
The engine is a "free-cylinder" design, in which the entire engine is mounted on springs and allowed to vibrate slightly. This allows the displacer to be driven by positive feedback from the motion of the power piston and the magnets in the linear-alternator magnets, which have a combined weight of 10 kg.

Diagram of a free-piston engine as a gas generator for a gas turbine. The first gas turbine–mechanical locomotive in the world, Class 040-GA-1 of 1,000 hp (0.75 MW) was built by Renault in 1952 and had a Pescara free-piston engine as a gas generator. It was followed by two further locomotives, Class 060-GA-1 of 2,400 hp (1.8 MW) in 1959–61.
A free-piston gas generator is a free-piston engine whose exhaust is used to power a gas turbine. It combines the functions of compressor and combustion chamber in one unit. These machines were quite widely used in the period 1930–1960 but then fell out of favour. [1]
