Abstract (en)

A method for fuel injector installation in an engine comprises the steps of determining fuel injector parameters specific to a particular fuel injector based on test performance data; associating the fuel injector parameters specific to the particular fuel injector in a machine readable format; and installing the fuel injector in an engine and retrieving and transferring the associated fuel injector parameters into a control unit of said engine. The control unit is configured to receive, for each fuel injector to be installed in said engine, fitting information relative to a predetermined, stored set of segments of a predetermined master performance curve, wherein each segment corresponds to a distinct, operating injector pulse width range; and the fitting information relative to the stored set of segments is comprised in the fuel injector parameters in machine readable format that are associated with the particular fuel injector.
