Failure Analysis

The project “Failure Analysis of
Fuel Injection Pump” used in Diesel Locomotive
Engines. The project was carried out at Diesel
Loco shed, Golden Rock, Tiruchirapalli. A
detailed study was undertaken in the fuel
Injection pump of Diesel Locomotive Engines
physically and based on the data collected a
failure analysis was done using a Total Quality
Management Technique, Failure Mode Effect
Analysis (FMEA). The causes of failure of
fuel injection pump was found to be the
breakage of push rod at its neck position due
to high Stress Concentration and increase
operating temperature of Internal combustion
engine radiation. The improvement could be
done on the material characteristics by addition
of high strength alloy materials to the high speed
