Webb27 dec. 2024 · The simulated Atkinson cycle also has the added benefit of additional fuel washing of the valves, from the delayed closing of the intake valves which the fuel-air mixture is pushed back through the intake valves to reduce pumping losses, at the expense of of low end power/torque. 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. Webb4 apr. 2024 · In the experimental study, the Atkinson cycle engine was converted from a standard spark-ignition engine using LIVC strategy and increasing the compression ratio. Some components of the spark-ignition engine including the cylinder head and the camshaft were modified to increase the compression ratio and to retard the IVC timing. choctaw event center calendar
