| 内容記述 | The frequency characteristics of loudness and vibration were investigated with respect to the indicator diagram on a direct injection diesel engine. The engine noise was influenced by the distribution of the mechanical sound when the frequency was lower than 1 kHz. And over that frequency range, engine noise was mainly influenced by combustion sound on load operations. Levels of sound and vibration were proportional to the gradient of cylinder pressure. Compared with the pressure and noise waves, the damping coefficient of sound was linearly decreased to 3 kHz and increased in higher frequency as structural acoustic damping character of the diesel engine. This result was caused by the natural frequency of cylinder's bending vibration. | |||||||
