The paper describes an investigation to identify the sources of forces which cause the vibration of different parts of the engine structure in a turbocharged heavy duty diesel engine of 2 litres/cylinder capacity. The differences in vibration response at the main bearings and on the engine outer surfaces is shown. Results of overall dynamic stiffness measurements at the main bearings indicate that the oil film has a negligible effect on the behaviour of the major vibration response. A model is put forward for an absolute prediction of the engine outer surface vibration. The model can be seen as an alternative or complement to current F.E. techniques. A comparison between predicted and measured vibration on the crankcase is presented. Predicted vibration response spectra are used to show the relative contribution of liner and bearing forces to the overall crank-case and cylinder block vibration of the engine.
