A basic study on vibration characteristics of fuel injection pumps - On vibration characteristics of a high-pressure fuel injection pump with a bracket

摘要

For a low-pressure fuel-injection pump and a high-pressure fuel-injection pump, the vibration characteristics of their bodies have been examined from vibration experiments and theoretical analysis in the previous paper. This study refers to the vibration characteristics of a high-pressure type fuel injection pump body with a bracket for a automobile diesel engine. For the two types of different injection pressure fuel injection pump, the vibration characteristics of the bodies with bracket have been analyzed bodies through the vibration characteristics of each pump body, bracket and body with bracket examined from the experiments described in the previous report.
