2. Pneumatic motor - Wikipedia

   en.wikipedia.org/wiki/Pneumatic_motor

   A pneumatic motor (air motor), or compressed-air engine, is a type of motor which does mechanical work by expanding compressed air. Pneumatic motors generally convert the compressed-air energy to mechanical work through either linear or rotary motion.

3. Angelo Di Pietro (inventor) - Wikipedia

   en.wikipedia.org/wiki/Angelo_Di_Pietro_(inventor)

   The Di Pietro Motor, developed by the Australian company EngineAir, is a positive displacement pneumatic rotary engine powered by compressed air. Per unit of power, it is smaller than any internal combustion engine although the size may differ between models. The CA-patent for this engine was published in 2001. [3]

4. Rotary engine - Wikipedia

   en.wikipedia.org/wiki/Rotary_engine

   Another motorcycle with a rotary engine was Charles Redrup's 1912 Redrup Radial, which was a three-cylinder 303 cc rotary engine fitted to a number of motorcycles by Redrup. In 1904 the Barry engine , also designed by Redrup, was built in Wales: a rotating 2-cylinder boxer engine weighing 6.5 kg [ 3 ] was mounted inside a motorcycle frame.

5. Compressed-air vehicle - Wikipedia

   en.wikipedia.org/wiki/Compressed-air_vehicle

   Dipietro eccentric shaft, rotary vane air engine. There have been several dubious claims with undisclosed information. However, the "Di Pietro" engine has been partially tested with CAD and finite element analysis program and published in scientific papers by Jarosław Zwierzchowski from Lodz University of Technology in 2017, [4] which is an eccentric shaft vane motor that uses low air pressure.

6. Clerget aircraft engines - Wikipedia

   en.wikipedia.org/wiki/Clerget_aircraft_engines

   The Clerget rotary engines were air-cooled with either seven, nine or eleven cylinders. They were fitted with a double thrust ball race, which enabled them to be used either as a pusher or as a tractor engine. The engines worked on a four-stroke cycle. The chief points of difference from other rotary engines were: The pistons were of an ...

7. Rotax 532 - Wikipedia

   en.wikipedia.org/wiki/Rotax_532

   The standard engine includes a muffler exhaust system and an intake air filter. The standard starter is a recoil start type, with an electric starter optional. An integral alternating current generator produces 12 volts. [1] The Rotax 532 was replaced in production by the improved Rotax 582 engine design. The 582 increased the cylinder bore ...

   Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...
