Abstract
To attain a reduction in NOx emissions, various aftertreatment technologies are being developed. In addition to the emission control, these systems require fault diagnostic schemes to detect failure and diagnose faults. For detecting faults, one approach is to measure NOx emissions using a NOx sensor that serves the purpose of control and diagnostics for these systems. Moreover, an alternative approach has been developed for Lean NOx Trap (LNT) catalysts which use substrate temperatures for feedback and diagnostics. This paper will exploit both approaches using an experimental setup up.
