The article describes the programme of investigating vehicle engine noise at the Institute of Sound and Vibration Research (ISVR), Southampton University. The research has shown that the ignition of fuel/air mixtures in a diesel engine results in a rise in cylinder pressure which excites engine structure vibration. This results in a high-frequency impulsive noise. Mechanically induced noise generated by the crank mechanism is also impulsive and is indistinguishable from combustion induced noise. Investigation of over 50 commercial engines at ISVR has established basic relationships between combustion induced noise and engine parameters of speed, size and load. /TRRL/
