Formatted abstract
Intake system for UQ Formula-SAE hasn't been through major design changes since 2010. Based on previous FSAE-A competition, the driver's respond to the event is that there is insufficient torque delivery in the low rpm range, causing lag in acceleration. The low torque delivery is directly related to low volumetric efficiency, which is contributed by the design of an intake system and the anti-resonance waves from the intake into the engine cylinders. Several resonances model were studied in response to the accuracy of predicting the resonance peak in the intake system. Literature reviews and SAE papers are analysed to identify possible improvements that can be proposed and made to the current intake system to improve the torque delivery. While Organ Pipe Model and Helmholtz Resonance Model can be a reliable preliminary design tool for predicting the peaks of an intake system from resonance waves, the Impedance Transform Model is able to visualise the resonance and anti-resonance activity of the entire intake system throughout all engine speed in a graphical manner. A new design for the intake restrictor is tested with Ansys:CFX computational fluid software and results show 21% improvement in airflow compared to the previous restrictor. Other several design possibilities for the intake system are also discussed and recommended in this thesis.
