Increased use of turbocharging and optimization of the combustion chamber parameters in present and future automotive diesel engines tends to accentuate the mechanical sources of excitation. These sources mainly consist of piston slap, timing gear rattle, bearing impacts, fuel injection operation, valve system and accesories. The noise and vibration generating mechanisms of these exciting forces can be classified broadly as mechanical impacts or development of impulsive oil film pressures, causing subsequent structural deformation of the engine components. Piston slap excitation has been dealt with in previous papers. This paper discusses the other mechanical sources together with their experimental identification and some control methods and shows how these sources can become significant in future low-noise engines.
