Atkinson produced three different designs that had a short compression stroke and a longer expansion stroke. The first Atkinson-cycle … See more

The next engine designed by Atkinson in 1887 was named the "Cycle Engine" This engine used poppet valves, a cam, and an over-center arm to produce four piston strokes for every … See more

Atkinson's third design was named the "Utilite Engine". Atkinson's "Cycle" engine was efficient; however, its linkage was difficult to balance for high speed operation. Atkinson … See more

In the late 20th century, the term "Atkinson cycle" began to be used to describe a modified Otto-cycle engine—in which the intake valve is held … See more

The first implementation of the Atkinson cycle was in 1882; unlike later versions, it was arranged as an opposed-piston engine, the Atkinson … See more

The ideal Atkinson cycle consists of:
• 1–2 Isentropic, or reversible, adiabatic compression
• 2–3 Isochoric heating (Qp) See more

The Atkinson cycle can be used in a rotary engine. In this configuration, an increase in both power and efficiency can be achieved when … See more
