Research facilities to investigate diesel engine noise at the Perkins Engines Group Centre at Peterborough are described. Some of the results from research are outlined. Diesel engine noise has been correlated against engine parameters such as speed, load, ignition timing and combustion. The group now has three well equipped semi anechoic noise cells and a noise laboratory with both analogue and digital measurement and analysis systems. Each cell has fully automatic methods for controlling speed, load and engine temperature. In 1973 a project was started aimed at developing a method of predicting engine noise at the design stage. Theoretical investigations involving a finite element technique and a statistical energy procedure are supplemented by practical measurements. The technique involved entails dividing the engine into small plate-like sections and calculating the noise radiation from each using known surface vibration characteristics. /TRRL/
