OPTIMIZING RELIABILITY: "SOLUTIONS FOR EXTENDING ROLLER AND SHOE LIFESPAN IN COMMON RAIL FUEL INJECTION PUMPS"

Abstract

The objective of the paper to fulfill the customer requirement through quality, cost, delivery and service by the manufacturer. Never ending quality improvement is now recognized as essential for any organization. The objective of this project is to analyze, identify root cause, study and implement the change for a customer quality concern in hydraulic head, one of the parts in high pressure common rail fuel injection pump part. I attempt here to present the objective of the project a unique and workable approach to that method we have adopted. In spite of many improvements (DLC Coating) on the roller to improve the wear, TATA motors, one of the main customers of us is complaining on roller and shoe wear on the common rail fuel injection pump. The complaint recorded as 30 to 40IPTV considering the period of 24 MIS. This wear directly affects the working function of pump and finally leads to pump seizure. With the back ground I have taken up this project. We have planned to collect all the data about this complaint. Finally we the team had analyzed and identified the root cause and identified the scope of improvement to be done on Hydraulic head one of the fuel injection part where the roller has contact with this part in order to eliminate the roller and shoe wear. So the scope of my project will be fully based on analyzing the possible root cause, study possible changes, improvement in design, implement the change, validate and monitor the performance and analyze the future scope of work.
