    On the diagnosis and analysis of an automotive fuel pump noise
    (Bursa Uludağ Üniversitesi, 2020-08-11) Yağcı, Ayhan; Meriç, Cem; Özkan, Aytekin
    This study aims to solve a low-frequency tonal fuel pump noise involving a roller-cell type of fuel pump located inside a metal fuel tank. Firstly, possible noise transmission paths are investigated. Then, the contribution of each component and/or the boundary condition to the fuel pump noise phenomenon is investigated step by step mainly with experimental methods. The effect of the differences in the structural design of the pump, sub-components ve interfaces are tested and analyzed. Finally, the solution alternatives are discussed and the proposed solution is tested and verified through objective NVH tests. It is shown that a 10 dB improvement in noise level can be obtained with the application of the proposed solution.
