Animation of the Atkinson differential engine 1932 Junkers Jumo 205 diesel aircraft engine. One of the first opposed-piston engines was the 1882 Atkinson differential engine, [7] which has a power stroke on every rotation of the crankshaft (compared with every second rotation for the contemporary Otto cycle engine), but it was not a commercial success.
Fairbanks Morse Opposed Piston liner and water jacket. The 38 8-1/8 engines are inline diesel engines, with combustion occurring between two opposed pistons within a single cylinder liner. The engine has a bore of 8-1/8 inches (206.4 mm), a stroke of 10 inches (254.0 mm) for each piston, and the cylinder height is 38 inches (970 mm).
The engines are all carburetor-equipped, feature dual magneto ignition and have a displacement of 233 cubic inches (3.82 L). The first O-235 model was certified on 11 February 1942. [2] The O-235 was developed into the lighter-weight Lycoming IO-233 engine for light sport aircraft. [3]

The F-23 is intended to compete with the 50 hp (37 kW) Rotax 503 and is differentiated from the Rotax powerplant by offering a horizontally-opposed cylinder layout. The F-23 uses free air cooling and piston-ported induction, with dual Bing 34mm slide or optional diaphragm type carburetors. The cylinder walls are electrochemically coated with ...
The Jumo 204 was an opposed-piston, inline, liquid-cooled 6-cylinder aircraft Diesel engine produced by the German manufacturer Junkers. It entered service in 1932. It entered service in 1932. Later engines in the series, the Jumo 205 , Jumo 206 , Jumo 207 and Jumo 208 , differed in stroke, bore, and supercharging arrangements.
The Swashplate engine with the K-Cycle engine is where pairs of pistons are in an opposed configuration sharing a cylinder and combustion chamber. A Delta engine has three (or its multiple) cylinders having opposing pistons, aligned in three separate planes or 'banks', so that they appear to be in a Δ when viewed along the axis of the main-shaft.
Opposed-piston diesel engines are rare enough at this size, the rocker lever arrangement was almost unheard of. Probably the only engine using a similar arrangement was the pre-war Sulzer ZG9. [9] This was an opposed-piston engine with a choice of two, three and four cylinders (2ZG9, 3ZG9, 4ZG9); the two-cylinder version developed 120 bhp.
