Abstract This report presents the results of an engineering study to design and demonstrate methods of reducing diesel engine block vibration and radiated noise. The Detroit Diesel Allison 6V-92TTA heavy duty diesel truck engine was selected for the demonstration. This engine was structurally modified to reduce vibration and noise due to the unit injectors and piston-slap. The modifications were designed so that the noise reduction was achieved without degrading engine performance, fuel economy, or emissions. A 4dBA reduction of overall engine noise reduction was demonstrated.
