Abstract
A system and method for identifying engine wear based on engine oil debris is provided. The provided system and method utilize metallic debris data provided in summary reports. For each object of metallic debris, a zap count, an initial (pre-zap) impedance and an impedance change (post zap) are processed with configurable reference variables. Alerts (suggesting potential engine wear) are generated responsive to the impedance values of the objects of metallic debris and the reference variables.
Claims16
A method for identifying potential engine wear of an engine based on chip zap data reflecting engine oil debris, the method comprising:
- at a processor,
- initializing a threshold zap count as a number of zaps that can be tolerated;
- initializing a zap counter to zero;
- receiving, from an external source, a summary report of the chip zap data, the summary report having one or more lines, each line including:
- a date, a time, an initial impedance (initial Z), a post-zap impedance, a delta impedance (delta Z), and a number of zaps;
- creating a cutoff date;
- processing a line of the summary report to identify the date, the initial Z, the delta Z, and the number of zaps;
- and
- incrementing the zap counter by the number of zaps, when the date is within the cutoff date;
- determining whether the zap counter is greater than the threshold zap count;
- and
- generating commands to annunciate an alert indicating potential engine wear when the zap counter reaches the threshold zap count.
A system for identifying potential engine wear of an engine based on chip zap data reflecting engine oil debris, the system comprising:
- a processor;
- and
- a computer readable storage medium coupled to the processor;
- wherein the processor is configured to initialize a threshold zap count as a number of zaps that can be tolerated;
- initialize a zap counter to zero;
- receive, from an external source, a summary report of the chip zap data, the summary report having one or more lines, each line including:
- a date, a time, an initial impedance (initial Z), a post-zap impedance, a delta impedance (delta Z), and a number of zaps;
- create a cutoff date;
- process a line of the summary report to identify the date, the initial Z, the delta Z, and the number of zaps;
- and

- determine whether the zap counter is greater than the threshold zap count;
- and
- generate commands to annunciate an alert indicating potential engine wear when the zap counter reaches the threshold zap count.
