Auto-Populating Electronic Trim Files for Fuel Injectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Human error in obtaining or loading electronic trim files for fuel injectors can lead to incorrect associations, resulting in sub-optimal performance due to mismatched trim files during service or component swapping in machine systems, especially in internal combustion engines with stringent emissions regulations.
Innovation Solution
An automated method where an on-board electronic control system interrogates electronically controlled components, reads unique electronic trim files, and populates a data structure upon activation, ensuring correct trim files are used for each component, thereby reducing servicing errors and ensuring optimal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated electronic trim strategy is used, then productivity is improved, but device complexity increases
Solution Approach 1:
The electronically controlled component performs self-identification and self-trimming by automatically providing its unique identifier and retrieving the corresponding trim file from storage, eliminating the need for manual intervention and reducing system complexity despite automation
Solution Approach 2:
Trim files are pre-stored in machine readable component storage media associated with each electronically controlled component, allowing the system to automatically retrieve and apply the correct trim file without complex real-time processing or manual configuration
2Reliability
If manual trim file loading is used, then device complexity is reduced, but reliability deteriorates due to human error
Solution Approach 1:
The system eliminates human error by enabling the electronically controlled component to automatically provide its unique identifier and retrieve the corresponding trim file, ensuring accurate association without manual intervention
Solution Approach 2:
The system establishes a feedback loop where the electronically controlled component communicates its identity to the control system, which then retrieves and applies the correct trim file, ensuring accurate matching through automated verification

AI summary
Operating a machine system includes triggering, based on activation of an on-board electronic control system, interrogation of electronically controlled components installed in a machine to read a plurality of electronic trim files each resident on a different one of the electronically controlled components. A data structure on an electronic storage medium in the control system is populated with the electronic trim files each time the control system is activated, such as by turning on an ignition switch. Operating the machine system also includes outputting control signals based on the electronic trim files to run the machine system based on operation of the electronically controlled components responsive to the outputted control signals.
