The torsional vibrations which occur on the fuel injection pump of an automotive diesel engine were investigated. Calculations and tests showed that as well as vibrations transmitted from the crankshaft, the fuel pump could vibrate at the natural frequency of the torsional system consisting of the pump and the drive coupling against an infinite mass. This was excited by harmonic torques produced by the pump. Calculations were made to show the effect of variables on the natural frequency of the pump system including the instance when a crankshaft natural frequency coincided with a pump natural frequency. Calculations were also made of the effect of the engine harmonic torques on the pump vibrations. The results were verified by experiments.
