Abstract This report presents the results of an engineering study to design and demonstrate a method of reducing piston-slap noise for an in-line, heavy duty truck diesel engine. The Cummins NTC-350 engine was selected for the demonstration. The engine heads and cylinder liners were structurally modified to reduce the vibration transmission to the engine block and the radiated noise. The modifications were designed to achieve a 5 dBA noise reduction without degrading engine performance, fuel economy, or emissions.
