Method of providing trim data for a fuel injection device
First Claim
Patent Images
1. A method of providing electronic trim data for a fuel injection device to an engine system, the method comprising:
- reading an identifier associated with the fuel injection device, the reading of the identifier comprising scanning a code region on the fuel injection device;
reading compressed trim data from the code region;
accessing a database containing trim data associated with the identifier;
attempting to download trim data for the fuel injection device;
using the compressed trim data to error check the downloaded trim data;
the method further comprising either uploading the downloaded trim data to the engine system for use in controlling fuel injection device operation in the event the downloading step succeeds or uploading the compressed trim data to the engine system for use in controlling fuel injection device operation in the event the downloading step fails;
wherein the identifier read in the reading step is sent to a computer and the accessing step comprises the computer connecting to the database.

11. A system for providing electronic trim data for a fuel injection device to an engine system, the system comprising:
-
a fuel injection device identifier reader configured to scan a code region on the fuel injection device in order to obtain an identifier and to read compressed trim data from the code region; a computer arranged to be in communication with the fuel injection device identifier reader and a network connection module for connecting to a trim data database upon receipt of the identifier from the fuel injection device identifier reader; wherein the computer receives instructions from a computer-readable storage medium, wherein said instructions control the computer to poll the trim data database once a connection has been established for trim data associated with the identifier, wherein said instructions further control the computer to attempt to download the trim data from the trim data database and to upload it to the engine system in the event the downloading step succeeds or to upload the compressed trim data to the engine system for use in controlling fuel injection device operation in the event the downloading step fails. - View Dependent Claims (12)

13. A method of providing electronic trim data for a fuel injection device to an engine system, the method comprising:
-
reading an identifier associated with the fuel injection device, the identifier being stored in a code region on the fuel injection device; accessing a database containing trim data associated with the identifier; downloading the trim data for the fuel injection device; uploading the downloaded trim data to the engine system for use in controlling fuel injection device operation wherein the reading step comprises scanning the code region on the fuel injection device in order to obtain the identifier and additionally comprises reading compressed trim data from the code region, the method further comprising using the compressed trim data to error check the downloaded trim data; wherein the identifier read in the reading step is sent to a computer and the accessing step comprises the computer connecting to the database. - View Dependent Claims (14)
