Abstract

Fuel supply advanced angle is one of effective parameters in monitoring the state or diagnosing the fault of diesel engine. So it is important to study fast and accurate detection method of fuel supply advanced angle. The embedded sensor is used to measure injection waveform of high-pressure fuel tube. The detection algorithm is established, and the fuel supply advanced angle is calculated by comparing the injection waveform with top dead center signal. In situ calculated advanced angle coincides with the rated parameter of diesel provided by manufacturer and verify the accuracy of the method.
