The Atkinson-cycle engine is a type of internal combustion engine invented by James Atkinson in 1882. The Atkinson cycle is designed to provide efficiency at the expense of power density. A variation of this approach is used in some modern automobile engines.

An Atkinson cycle engine can complete all four strokes with a single rotation of the crankshaft. Read more about Atkinson cycle engines at HowStuffWorks.

Jun 20, 2024 · While the electric motor is powerful for low-speed driving but not as efficient for cruising, Atkinson cycle engines are less good at strong acceleration but great at a constant speed for...

Aug 4, 2016 · While Atkinson’s engines weren’t successful, his thermodynamic cycle is still in wide use, mainly in gas-electric hybrids. The key advantage is higher efficiency than is achievable in an Otto...

Oct 9, 2017 · But just what is the Atkinson cycle, and what does it mean if you buy a car with an Atkinson cycle engine? Simply put, it's a valve timing adjustment to the standard Otto cycle, which all...

In 1882, an engineer James Atkinson invented the Atkinson cycle. A modified version of the Atkinson cycle is employed in several contemporary car engines. Previously, the Atkinson cycle was exclusively associated with hybrid electric vehicles like the early models of the Toyota Prius.

Mar 23, 2023 · Do you know the difference between an Atkinson, Miller, or Otto Cycle four-stroke engine? How about the history behind each engine design?

Nov 4, 2014 · Invented by James Atkinson in England (first patented in 1886 and then refined through a second patent in 1887), the Atkinson cycle engine completed all four strokes of the Otto cycle engine in a single crankshaft revolution instead of the two required by the Otto.

May 22, 2019 · Atkinson Cycle – Atkinson Engine. In 1882, a British engineer, James Atkinson advanced the study of heat engines by inventing of several heat engines that have an increased efficiency over the Otto cycle. This was achieved by use of variable engine strokes from a complex crankshaft.

Mar 28, 2024 · Atkinson cycle engines generate maximum revolutions of 5,000 rpm due to their special timing configuration, therefore providing powers belonging to engines with smaller displacements and less performance.
