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).

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.
Are gas turbines "free piston" engines, or "piston free"? 173.68.56.71 21 October 2011 Piston free. The point of a free piston engine and its similarity is that it's like the core of a gas turbine (compressor, combustor and the turbine that drives the compressor), but without the power turbine.

At least 35 children were killed and six others critically injured in a crowd crush at a funfair in the Nigerian city of Ibadan on Wednesday, police said.
It was originally developed around 1900 for the twin-cylinder Lanchester car engine where it allowed perfect balancing of the inertial forces on both pistons. A current example of its use is on beta type-Stirling engines; the drive's complexity and tight tolerances, causing a high cost of manufacture, is a hurdle for the widespread usage of this drive.
