Summary: | At least some embodiments of present disclosure direct to a fuel injection timing drift detection and/or compensation system. In some cases, the system collects or receives a series of fuel pressure data measured by one or more fuel pressure sensors. The system is configured to receive an indication of fuel flow cutout and a start-of-injection command signal. The system calculates a set of pressure drops using the series of fuel pressure data and identifies a selected pressure drop greater than a predetermined threshold to determine a measured start-of-injection timing based on the selected pressure drop. The system is further configured to evaluate whether a fuel injection drifting occurs based on received start-of-injection command signal and the measured start-of-injection timing. In some cases, the fuel injection drifting is used to either compensate fuel injection timing or raise a flag indicating the drifting. |
