The Research on the Fuel Performance of Fsae EFI Engine

摘要

For the modeled engine, the soft AVL-BOOST is applied to do the single-dimensional cycling simulation and calculation. And then the engine performance after assembling the improving limiter (its diameter is 20 mm) is analyzed. According to the calculation and analysis, the torque and pneumatic efficiency are largely affected by limiter, the maximum torque and pneumatic efficiency decreases 20 percents and 30 percents respectively. The limiter not only improves the engine's fuel performance, but also reduces its power performance.
