  • Method for analyzing injector performance
    Patent number: 9605611
    Abstract: Injector drift for a diesel engine are detected by reconfiguration of injection patterns from one pattern into a pattern with a different number of pulse points while attempting to hold total fuel injected constant. If a particular injector is subject to drift then changes in the pulse pattern result in an increase or decrease in fuel injected and consequential variations in engine speed. By applying alternating injection patterns at constant fuel demand and allowing engine speed time to stabilize, a rhythmic variation in engine speed/torque will appear which can be detected using one of a number of techniques.
