| Abstract(E) | To achieve overwhelming quietness like BEV, which is one of the attractions of 100% electrically driven hybrid vehicles we have built a design technology to improve not only the volume of the engine noise but also the engine sound quality. The mechanism of sound quality deterioration is clarified by focusing not only on the vibration reduction due to the separation of the crankshaft and powerplant resonance frequency, but also on the node position of the crankshaft bending resonance mode and the transmission sensitivity from each crankshaft main journal to the engine mount. As a result, we clarified the important design elements and criteria for improving sound quality. |
