Model-based fault detection and diagnosis for common-rail injection systems

Abstract

In order to guarantee the reliability and availability of electronically controlled multi injection systems of modern diesel engines, an improved fault detection and diagnosis gains in importance. For this purpose especially model-based algorithms with signal- and process models can be applied. Thus, Technische Universitat Darmstadt developed a model-based fault detection module for common-rail injection systems among other things in the FVV project “Diagnosis Systems for Diesel Engines” (No. 885 and 952).
