Solenoid Valve Failure Detection for Electronic Diesel Fuel Injection Control Systems
نویسندگان
چکیده
Possible faults existing in electronic diesel fuel injection control (EDC) systems include rack deformation, solenoid valve failure, and rack-travel sensor malfunction. Among these problems, the solenoid failure is the most likely to occur for in-use diesel engines. This paper focuses on developing the algorithm that can clearly classify the usability of a solenoid valve without disassembling the fuel pump of the EDC system. Key parameters to feature the failure of the solenoid valve are determined. And a detection algorithm is discussed. Experimental results show that the proposed algorithm can identify the solenoid valve failure precisely. Copyright © 2005 IFAC Kew words: Diesel engines, Fault diagnosis, Actuator.
