Method and system for determining remaining useful life for an injector of a reciprocating engine

A system for determining remaining useful life of an in-use injector of a reciprocating engine, the system comprising:

• an input module configured for receiving one or more operating parameters related to the reciprocating engine;
• a nozzle wear relationship database having nozzle wear-relationship data for the in-use injector for a plurality of duty cycles;
• an emission relationship database for storing emission relationship data predictive of emission levels for a standard injector at each of a plurality of nozzle wear levels;
• an emission level calculator module for determining actual emission levels for the in-use injector based on the nozzle wear relationship data, and the emission relationship data;
• a life determination module for determining the remaining useful life of the in-use injector based on the actual emission levels;
• and
• a controller configured for controlling an operation of the reciprocating engine based on the actual emission levels, if the remaining useful life of the in-use injector is within an operable range, or triggering a new injector procurement alarm if the remaining useful life of the in-use injector is not within the operable range.
