Abstract
The present technology provides systems for monitoring particulate matter buildup on a filter installed in the engine exhaust stream of a vehicle. A filter differential pressure sensor monitors a pressure differential across the filter. A downstream differential pressure sensor monitors a pressure differential across an exhaust stream outlet. A processor monitors a particulate buildup value based at least in part on the pressure differential across the filter and the pressure differential across the exhaust stream outlet. A method for monitoring particulate buildup is also provided. The method monitors a pressure differential across the filter, and determines a downstream exhaust flow rate based on a pressure differential between a filter outlet housing and an exit pipe, where the diameter of the filter outlet housing is greater than the diameter of the exhaust exit pipe.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
