A Study on the Noise Generating Mechanism of a Fuel Injection Pump 951345
This paper has clarified the noise generating mechanism on the BOSCH AD type fuel injection pump by using numerical and experimental analysis methods.
The calculated vibration of each part has been verified to coincide well with the measured acceleration data. Based on the detailed analysis, the major noise source of the injection pump was found to originate from the tappet vibration caused by the steep pressure drop at the end of injection.
After performing some parameter studies by using the simulation model, it turned out that some specifications of the injection pump influenced its sound power.
