AI Technical Summary
Existing technologies are insufficient for accurately measuring minute leaks in high-pressure common rail injectors, and the measurement process is time-consuming.
A static leakage test system for high-pressure common rail system injectors was built using fluorescent diesel solution and a fluorescence spectrophotometer. The system was constructed by adding fluorescent diesel solution to the high-pressure common rail system and calculating the leakage amount using the fluorescence intensity value. The system includes components such as fuel tank, ECU, pressure gauge and electronically controlled injector to achieve accurate measurement.
It enables accurate and rapid measurement of minute static leakage in high-pressure common rail injectors, provides leakage analysis data for component gaps, and verifies the feasibility of sealing surface design and processing technology.
