Why does Toyota use Atkinson cycle engines?

Webb7 dec. 2024 · The Toyota 2GR engine avoids this by implementing port injection as well. 2GR-FKS engines can also switch to a simulated Atkinson cycle for better fuel economy … The ideal Atkinson cycle consists of: 1–2 Isentropic, or reversible, adiabatic compression2–3 Isochoric heating (Qp)3–4 Isobaric heating (Qp')4–5 Isentropic expansion5–6 Isochoric cooling (Qo)6–1 Isobaric cooling (Qo') Visa mer 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 … Visa mer The first implementation of the Atkinson cycle was in 1882; unlike later versions, it was arranged as an opposed piston engine, the Atkinson … Visa mer 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 realized an improvement was needed to make his cycle more … Visa mer 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 … Visa mer 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-known design was the cycle engine, which used … Visa mer 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 revolution of the crankshaft. The intake and compression strokes were … Visa mer 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 … Visa mer Webb15 maj 2024 · A method is described for the prediction of site-specific surface ground motion due to induced earthquakes occurring in predictable and well-defined source zones.
