System and method for detecting spall initiation and defining end of life in engine components
First Claim
1. A vehicle, comprising:
- an engine;
an oil debris sensor coupled to the engine;
a communications system; and
a processor communicatively coupled to the oil debris sensor and the communications system, the processor configured to;
increment a counter when the oil debris sensor detects a particle over a predetermined size;
increment the counter when a mass of a plurality of particles under the predetermined size exceeds a predetermined mass threshold;
transmit, via the communications system, a first message when the counter exceeds a predetermined counter threshold; and
reset the counter when the counter does not exceed the predetermined counter threshold within a predetermined amount of time.

Abstract
A system and method are provided for detecting a spall in an engine. The vehicle, for example, may include, but is not limited to an engine, an oil debris sensor coupled to the engine, a communications system, and a processor communicatively coupled to the oil debris sensor and the communications system. The processor may be configured to increment a counter when the oil debris sensor detects a particle over a predetermined size, increment the counter when a mass of a plurality of particles under the predetermined size exceeds a predetermined mass threshold, transmit, via the communications system, a first message when the counter exceeds a predetermined counter threshold, and reset the counter after predetermined amount of time.
