Assessment of diagnostic usefulness of vibration of the common rail system in the diesel engine

The paper presents an assessment of diagnostic usefulness of the vibration measurements and analysis of selected components of the common rail system in the diesel engine. Measurements were performed of the selected components of the CR system and changes were determined in the time and frequency structure of the recorded vibration signals. The research has shown that vibration recorded on the injector's housing and the rail of the common rail system is useful diagnostic information for the evaluation of the technical condition of the fuel supply system of a compression ignition engine.
