Throttle Body Intake DOE

Problem Statement

• A DOE (Design of Experiment) was done on the throttle body intake.  
• Three different designs were used as initial runs (Low Intake Elbow, High Flow Intake Elbow, Box Intake Elbow)
• Two variables were altered for this experiment; throttle body flange angle and spline gap.

• The max velocity at the outtake was used as the main result in deciding which design proved to be best.

Results

The top three designs were selected...

3847_splinegap_1

3848_splinegap_2

3847

Conclusion

• Throttle body flange angle and spline gap were the two main variables that could alter the max velocity at the exit.  
• Of the two, changing the spline gap yielded the highest max velocity.  
• Further design will be done when final measurements are taken at throttle body.
