ABSTRACT:
A system for analyzing a substrate material for a diesel or other internal combustion engine exhaust filtration performance includes a valve that actuates within an exhaust system to modulate engine exhaust back pressure and correspondingly maintain a desired filtration velocity to influence a variable parameter within the system, based at least in part on an exhaust characteristic such as a sensed exhaust pressure differential defined across a substrate material.
