The noise of the injection pump includes three components: the direct pump noise (noise radiated from the pump housing), the pump-induced engine noise (noise radiated from the engine block, excited by body noise introduced from the injection pump) and the pump drive noise (belt, chain or gearwheels). The mechanisms which affect and determine the pump-induced engine noise and the pump drive noise are to be analysed in detail and discovered in this Research Project for a car and commercial vehicle engine. Experimental and calculation investigations are carried out for this purpose. By optimising the dynamic properties of the pump fixing, reduction in the engine noise induced by the injection pump is to be achieved for the car and commercial v...
