Alternative Pathways for Threshold HD-OBD Monitoring

This presentation will look at the problem of that Threshold HD-OBD monitoring for PM as well HC rely on indirect measurement methodologies as there is currently no PM or HC sensor accurate and robust enough to be feasible for mass production as well as PM thresholds cannot be monitored with conventional measurement devices and the NH3 slip currently not controlled. It will address thes problems with an alternative pathway for achieving these goals.
