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.
1919 Napier Lion II aircraft engine with three cylinder banks. Any design of motor/engine,be it a V or a boxer can be called an "in-line" if it's mounted in-line with the frame/chassis and in-line with the direction of travel of the vehicle.When the motor/engine is across the frame/chassis this is called a TRANSVERSE motor.Cylinder arrangement is not in the description of how the motor/engine ...
The engine had one crankshaft and is very similar in concept to the EcoMotors OPOC engine design, except using a camshaft and valves, and not in opposed-cylinder configuration. The OPOC engine can be moduled with two, or more, engines coupled via an electric clutch between engines. When more power is needed the second engine is clutched in.
A similar idea was the swashplate engine, an axial form of cam engine. Although the forces in a cam engine are often greater and the frictional losses are high, they can also allow the use of larger bearing surfaces than a conventional crankshaft. Before the development of high performance bearing materials, [note 3] the cam and swashplate ...
The Soviet Shvetsov OKB-19 design bureau was the sole source of design for all of the Soviet government factory-produced radial engines used in its World War II aircraft, starting with the Shvetsov M-25 (itself based on the American Wright Cyclone 9's design) and going on to design the 41-litre displacement Shvetsov ASh-82 fourteen cylinder ...
The history of cam engines is connected to the development of engines, especially in the late 19th and early 20th centuries. Engineers and inventors explored different mechanical designs to improve engine performance. One of the earliest recorded cam engine concepts dates back to the 19th century, during the industrial revolution.
The Continental O-526 is a family of air-cooled flat-6 aircraft piston engines ... 6-cylinder air-cooled horizontally opposed aircraft piston engine; ... Power output ...
The absence of a camshaft also means that the parasitic load on the engine is lower, which is particularly useful in large marine engines, as it can equate to a large amount of power savings. With a camless engine, fuel injection and exhaust timing are directly controlled by an engine control unit and can be constantly changed and adjusted ...
