This paper describes the investigation of the mechanisms of engine front noise generation and the corresponding countermeasures employed in the development of Hino's medium duty diesel engine.The engine front noise, which had a noise peak in the 630 Hz 1/3 octave band, was investigated by experiment and it was concluded that there were two mechanisms as follows: Using both experimental and analytical methods, crankshaft vibration and acoustic resonance were reduced, thus yielding a substantial noise reduction.
