Beschreibung
Zusammenfassung:	A fuel system is disclosed. The fuel system may include at least one fuel injector, the at least one fuel injector having an injector body and one or more piezoelectric sensors located in the injector body. The fuel system may include a controller configured to: obtain, from the one or more piezoelectric sensors, one or more pressure measurements associated with a fuel injection process; determine a timing of the fuel injection process based on the one or more pressure measurements; determine an adjustment to the timing based on a comparison of the timing to a reference timing; and adjust the timing of the fuel injection process based on the determined adjustment.
