摘要： An engine control system comprises a fuel pump control module and a diagnostic module. The fuel pump control module controls a pressure pump to inject fuel into a fuel rail. The diagnostic module determines an estimated pressure increase within the fuel rail based on the injected fuel, compares an actual pressure increase within the fuel rail to the estimated pressure increase, and indicates when the actual pressure increase is less than the estimated pressure increase.

摘要： A fuel control system for an engine includes a control module that includes a fuel rail pressure module and a comparison module. The fuel rail pressure module determines a first fuel rail pressure of a fuel rail after a first event and a second fuel rail pressure of the fuel rail after a second event. The first event includes N conditions, a first of the N conditions comprises deactivation of a fuel pump of the engine, and N is an integer. The second event includes M conditions, a first of the M conditions comprises activation of a fuel injector, and M is an integer. The comparison module adjusts a fuel injector constant of the fuel injector based on the first fuel rail pressure, the second fuel rail pressure, and an injector activation period corresponding to the second event.
