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.
Claims20
An apparatus, comprising:
- a burned fuel determination circuit structured to determine a current quantity of burned fuel by an engine;
- and
- an estimated remaining life determination circuit structured to determine a remaining life of the engine based on the current quantity of burned fuel using a correlation between a quantity of burned fuel and a level of wear of a piston ring for the engine, wherein the level of wear of the piston ring is indicative of the remaining life of the engine.
A method, comprising:
- determining a current quantity of burned fuel by an engine;
- and
- determining a remaining life of the engine based on the current quantity of burned fuel using a correlation between a quantity of burned fuel and a level of wear of a piston ring for the engine, wherein the level of wear of the piston ring is indicative of the remaining life of the engine.
A system comprising:
- a processing circuit structured to:
- determine a current quantity of burned fuel by an engine;
- and
- determine a remaining life of the engine based on the current quantity of burned fuel using a correlation between a quantity of burned fuel and a level of wear of a piston ring for the engine, wherein the level of wear of the piston ring is indicative of the remaining life of the engine.
