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 ...
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.
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.
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.
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 ...
Radial engine in a biplane. The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages.
The 130 hp (97 kW) O-240 was a new engine design derived from the six-cylinder Continental O-360 and introduced in 1971. It is generally similar in overall dimensions to the Continental O-200, but with a higher 8.5:1 compression ratio, designed to run on 100/130 avgas. The O-240 delivers 30% more power than the O-200 while it weighs only 12% more.
Opposed-piston engines have been tried before in both 2 stroke and 4 stroke, the combination of the two different cycles is unique to this engine. The engine has a far greater efficiency over the break-even value known to combustion engines (about 35%) and closer to the one associated with steam turbines or electric engines (about 70%).
