SYSTEM AND METHOD FOR SENSING PARTICULATE MATTER

A computerized method includes receiving signals from a particulate matter sensor relating to an amount of particulates at a point in time within a time period in a diesel engine exhaust stream, calculating one or more running statistical parameters relating to a particle mass in the diesel engine e...

Beschreibung
Zusammenfassung:	A computerized method includes receiving signals from a particulate matter sensor relating to an amount of particulates at a point in time within a time period in a diesel engine exhaust stream, calculating one or more running statistical parameters relating to a particle mass in the diesel engine exhaust stream, determining an upper control limit for the amount of particulates, receiving a threshold for an allowable amount of particulates in the diesel engine exhaust stream, comparing the threshold to one or more of (a) a current instantaneous particulate reading from the particulate matter sensor and (b) the upper control limit for the amount of particulates, and generating an output signal when one or more of the current instantaneous particulate reading and the upper control limit for the amount of particulates are above the threshold.
