摘要:
A control system for an engine is presented. The control system can include a transition period waveform monitor module, a stuck fuel injector detection module, and a fuel injection control module. The transition period waveform monitor module measures an electrical signal of a fuel injector upon deactivation of the fuel injector. The stuck fuel injector detection module detects a stuck fuel injector when an accumulated deviation of the electrical signal from a parameterized estimated reference waveform is outside of a predetermined range. The fuel injection control module controls fuel injection in the engine based on the detection of the stuck fuel injector.
