A text-book on gas, oil ckclo air engines: The disadvantage of the four-stroke Atkinson-cycle engine versus the more common Otto-cycle engine is reduced power density. Almost all combustion engines on the market work thanks to a connecting rod-crank mechanism, whose motion is transmitted by one or more cylindrical pistons.
This modification of the Atkinson cycle allows the use of alternative fuels such as diesel and hydrogen. The 4 functioning phases of a Wankel engine: The Atkinson cycle can be used in a rotary engine. It is a system that, thanks to its construction simplicity and reliabilityhas remained substantially unchanged since the invention of the combustion engine second half of the nineteenth century to date.
Waniel, compared to traditional wankle engines, the Wankel engine has very poor performance combustion chambers.
Atkinson’s third design was named the “Utilite Engine”. The effective compression ratio is reduced—for the time the air is escaping ccilo cylinder freely rather than being compressed—but the expansion ratio is unchanged i.
The engine is the heaviest component on a complete racing kart. Atkinson’s engines were produced by the British Gas Engine Company and also licensed to other overseas manufacturers. While originally seen exclusively in hybrid electric applications such as the earlier-generation Toyota Priuslater hybrids and cciclo non-hybrid vehicles now feature engines with variable valve timingwhich can run ciclp the Atkinson cycle as a part-time operating regimen, giving good economy while running in Atkinson cycle, and conventional power density when running as a conventional, Otto cycle engine.

The total displacement of the Wankel is obtained by comparison with a similar 4-stroke engine with traditional pistons. The shape of the combustion chamber in relation to its shape, is more or less squared in part it is also obtained on the rotorwhile we know that in an efficient chamber the ratio between the surface and volume of the chamber should be as low as wahkel the top would be a spherical shape.

Atkinson also licensed production to other manufacturers. The second and most well-known design, was the cycle enginewhich used an over-center arm to create four piston strokes in one crankshaft revolution.
With this new design, Atkinson was able to eliminate the linkages and make a more conventional, well balanced, engine capable of operating at speeds up to rpm and capable of producing power every revolution yet cicl preserved all of the efficiency of his “Cycle Engine” having a proportionally short compression stroke and a longer expansion stroke.

Free energy Free entropy. Heat engines Heat cicli Thermal efficiency. The wankrl of the modern Atkinson cycle is to make the pressure in the combustion chamber at the end of the power stroke equal to atmospheric pressure.
The first Atkinson-cycle engine, the differential engineused opposed pistons. The Utilite operates much like a standard two-stroke except that the exhaust port is located at about the middle of the stroke. After the exhaust port is wanke, the piston begins to compress the remaining air in the cylinder. The intake and compression strokes were significantly shorter than the expansion and exhaust strokes. The reciprocating engine had the intake, compression, power, and exhaust strokes of the four-stroke cycle in a single turn of the crankshaftand was designed to avoid infringing certain patents covering Otto-cycle engines.
When this occurs, all available energy has been obtained from the combustion process.

While a modified Otto-cycle piston engine using the Atkinson cycle provides good fuel efficiency, it is at the expense of a lower power-per-displacement as compared to a traditional four-stroke engine. From Wikipedia, the free encyclopedia.
