Note that although their particulate size sensitivities overlap, their optimal particle size and
concentration responsiveness is different between sensors. Thus, particle mass concentration and
number can be extrapolated based on the evaluation of sensor modality and empirical references.
Multi-plex post-processing maps matched up with engine failure response modes may also enable
prediction for engine trouble diagnostic/failed DPF applications.
