A METHOD AND SYSTEM FOR PREDICTABLY ASSESSING PERFORMANCE OF A FUEL PUMP IN A LOCOMOTIVE

摘要

Method and system for determining degradation of fuel pump performance in a vehicle (10) having an internal combustion engine (58) is provided. The method allows for monitoring a signal indicative of a fuel value delivered by the fuel pump (56) based on first set of operational and environmental conditions. The method further allows for adjusting the value of the monitored signal for deviations from an estimated nominal fuel value based on a second set of operational and environmental conditions to generate an adjusted fuel value. The method further allows for comparing the value of the adjusted fuel value against the nominal fuel value to determine the performance of the pump.
