MODEL-BASED DIAGNOSTICS OF NOX SENSOR MALFUNCTION FOR SELECTIVE CATALYST REDUCTION SYSTEM |
摘要 |
Methods and systems for detecting faults with nitrogen oxides sensors used to detect the presence of nitrogen oxides in an exhaust effluent gas stream emitted from a combustion engine during its operation include providing a virtual nitrogen oxides sensor measurement compared with actual nitrogen oxides content measured by nitrogen oxides sensors.
