FSAE Intake Project
The Intake Design started from hand calculations, moved to an engine simulation for multivariate analysis with the plenum volume. Then the model was designed, and part manufactured from Nylon 11 GF by a Formlabs Fuse 1+ SLS 3d Printer.
The Model
The SolidWorks model is fully parametric, able to be modified from master sketches to be able to quickly adjust overall size and shape.
The Code
With significant help from my predecessor, we developed a MATLAB script that determines correct runner length based on RPM chosen. This code uses the Open end Organ Pipe concept. Tuning for a standing wave to increase volumetric efficiency at a desired RPM.
The Simulation
GT Power is an incredibly powerful engine simulator. With my input, my teammate Ryan developed a simulation of our CBR600RR engine, and used the intake plenum geometry to make the 1-D simulation. We then ran a multivariate analysis of different intake runner lengths, and plenum volumes to determine the best combination.
Testing
Data from the simulator was validated using a map sensor on each runner to determine the pressure change. This pressure change may be directly related to velocity using ‘continuity’ or Bernoulli’s principle.
