Simulated atkinson cycle
Webb14 sep. 2024 · With the Atkinson cycle we're adding another running compression reduction by keeping the intake valves open longer. So in the same engine running at full throttle the actual CR would be higher in Otto than Atkinson mode. Danno001 said: Compression can be varied from one similar displacement engine to the other by: WebbInterestingly, instead of running the simulated Atkinson cycle engine found in the second-generation Prius, the team fitted the closely related and more performance-oriented 1NZ-FE Otto cycle version to increase peak torque and top end power.

Webb26 mars 2024 · Atkinson’s Cycle This is best described as the process in which the intake valve is open longer than normal, resulting in a reverse flow of intake air into the intake manifold. This “simulated” Atkinson cycle is most notably used in the Toyota 1NZ-FXE engine from the early Prius. First impression. Webb22 maj 2024 · The term Atkinson cycle has been used to describe a modified Otto-cycle engine in which the intake valve is held open longer than normal to allow a reverse flow of intake air into the intake manifold. This reduces the compression ratio, but the expansion ratio remains the same.
