Abstract
A method of assembling an apparatus such as a fuel injector ( ) wherein parts or components are selected based on their capacity to compensate for variations in timing and delivery contributed by the tolerance variations of components assembled or measured for assembly prior to the selected components. The method involves an apparatus such as an injector of the type including a set of input parameters, a set of control parameters, and a set of observed performance parameters wherein the method includes the steps of performing tests ( ) on the injector ( ) to measure the values of the input parameters and determining the values of the set of control parameters ( ) using the set of input parameters to reduce performance parameter variability of the final assembly. The method also includes the steps of selecting ( ), for each control parameter, the component associated therewith and, assembling the selected components into the injector ( ).
