| Abstract: | Based on the characteristics of fuel injection pressure for high-pressure common rail system,the detection schemes for rail pressure sensor relative faults like sensor open circuit,power short circuit and drift were put forward.The diagnostic software was designed,the protection strategy was proposed,and all kinds of diagnosis tests were carried out on a diesel engine.The results show that the diagnosis method can identify the various faults of rail pressure sensor.The corresponding protection strategy can work timely,which meets the demand of OBD system application. |
