Tool to predict engine life using ring wear and fuel burned

Abstract:

Systems, apparatuses, and methods disclosed provide for estimating the remaining life for an engine. The method includes determining a correlation between a quantity of burned fuel and a level of wear of a piston ring for an engine. The level of wear of the piston ring is indicative of a remaining life of the engine. The method also includes determining a current quantity of burned fuel by the engine, and determining the remaining life of the engine based on the correlation and the current quantity of burned fuel by the engine.
