The vibration and sound signals of the engine under various operating conditions were measured and analyzed by applying a spectrum analysis and an order tracking analysis. In addition, a finite-element model of the engine was constructed via reverse engineering from a 3D scan. The main causes of engine vibration and noise were clarified and identified individually through the experiments and the engine model. Finally, the biodiesel-blended diesel fuel was used for the engine for comparing sound and vibration performance with the ultra-low sulfur diesel (ULSD). In mid to high range speeds, the biodiesel-blended diesel fuel does reduce the engine exhaust noise and vibration amplitude caused by the constant engine combustion explosion. |
