Gas Direct Injection (GDI) engines (like Palisade) have a reputation of fouling the intake valves with carbon deposits because gas does not flow through the valve and cannot clean it. To me, Atkinson Cycle engines have less of ... WebThe term Atkinson cycle has been used to describe a modified Otto-cycle engine. The intake valve is held open longer than normal to allow a reverse flow of intake air into the …
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. While originally seen exclusively in hybrid electric … See more Atkinson produced three different designs that had a short compression stroke and a longer expansion stroke. The first Atkinson-cycle engine, the differential engine, used opposed pistons. The second and best … 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 The ideal Atkinson cycle consists of: • 1–2 Isentropic, or reversible, adiabatic compression • 2–3 Isochoric heating (Qp) • 3–4 Isobaric 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 compared to the Otto cycle. This type of engine retains the one power phase per revolution, together with the different … 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 differential engine. In this, a single crankshaft was connected to two opposed pistons through a toggle-jointed linkage that had a … 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 open longer than normal, allowing a reverse flow of intake air into the intake manifold. This "simulated" … See more WebJun 16, 2012 · It is possible to create the same effect as the Atkinson cycle by changing the valve timing on an otherwise ordinary Otto four stroke engine. I really should illustrate this, but in the meantime I hope the following explanation will suffice: A cam is employed on both intake and exhaust valves (unlike my four stroke illustration).
