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.

A camless or free-valve piston engine is an engine that has poppet valves operated by means of electromagnetic, hydraulic, or pneumatic [1] actuators instead of conventional cams. Actuators can be used to both open and close valves, or to open valves closed by springs or other means.
The claim: Donald Trump can't travel to Canada because he is a convicted felon. A Dec. 3 Threads post (direct link, archive link) offers a theory as to why Canadian Prime Minister Justin Trudeau ...
The Lycoming IO-720 engine is a large displacement, horizontally opposed, eight-cylinder aircraft engine featuring four cylinders per side, manufactured by Lycoming Engines. [ 1 ] There is no carbureted version of the engine, which would have been designated O-720 and therefore the base model is the IO-720.
