Study on the Strategy for Failure Diagnosis of Wall-Flow DPF Based on Pressure Drop Characteristics

Abstract:

Based on the study of diagnosis principle of OBD, this paper probes into the pressure drop characteristics of wall-flow DPF, puts forward the failure diagnosis strategy of DPF based on the pressure drop characteristics of DPF, and actual vehicle tests have revealed that the devised diagnosis strategy can accurately identify various failure faults of DPF.
