Integrating Reliability, Availability, and Maintainability Issues for Analyzing Failures in Fuel Injection Pump

The main aim of this chapter is to enable system reliability analysts to provide a correct and timely diagnosis of reliability, availability, and maintenance requirements of their systems. Embarking upon the fundamental strength of failure analysis methods such as failure mode and effects analysis (FMEA), root cause analysis (RCA), and reliability block diagrams (RBD), the chapter provides Reliability, Availability, and Maintainability (RAM) analysis of pump failures. The pump system has been decomposed into a number of subsystems based on the components/parts. Failure and repair statistics of subsystems components have been used to model the reliability and maintainability of whole system. For ascertaining the maintenance priorities, FMEA has been used to spot out various possible failure modes, find out their effect on the operation of the pump, and to discover actions to alleviate the failures. The results of RAM analysis not only helps to identify the reliability and availability issues which may limit the production throughput but also helps to propose improvement in the design or selection of effective maintenance strategies.
