Stirling Engine and oil-free compressors [PDF]
E3S Web of Conferences, 2021 Refering to figure 1 [Fig.1], an oscillating « flipper » piston (1) and its associated chamber (2) are maintained without reciprocal contact. No oil is required because there is no contact and so no friction.

Development of Hydrogen-Free Diamond-Like Carbon Coating for Piston Rings
Tribology Online, 2017 The first piston ring application of a hydrogen-free diamond-like carbon (H-free DLC) coating to a mass-production gasoline engine reduces friction. It is found that the friction reduction effect between the cylinder bore and piston is 18%.

FREE-PISTON COMPRESSOR-ENGINES [PDF]
Nature, 1947 The Pescara free-piston engine has been developed in France during the last twenty years, and the paper gives a description of a portable air compressor which has been proved in commercial work, and is now in production. An explanation is given of those characteristics in which this engine differs from the orthodox engine-driven crankshaft compressor.

An optimization of free-piston engine generator combustion using variable piston motion
Advances in Mechanical Engineering, 2017 The free-piston engine generator has been a research focus lately due to its crankless structure and unconstrained piston motion, which brings about some weaknesses for the combustion process.
