| Abstract: | Through analysis on pressure waves of high pressure oil tube a fault diagnosis method based on pressure waves analysis is proposed for fuel injection system of diesel engine. At the same time the feature extraction and modal identification of pressure waves are elaborated. This technology is simple and practical, which provide an effective fault diagnosis and state monitoring method for fuel oil system. |
