Abstract
A filter retentate analysis system and method is disclosed, which provides information to diagnose the current and historical state of a system generating the retentate or through which the retentate has passed. The disclosure describes the analysis of retentate characteristics which may include the composition, amount, distribution, and physical or chemical properties of the retentate useful to monitor or diagnose the state, health, or operating history of a system or sub-system. The analysis is broadly applicable to wide range of systems and process ranging from engines and exhaust systems to production plants and equipment.
Claims9
A method of diagnosing an engine system generating retentate in communication with an engine exhaust system particulate filter in an engine exhaust system and containing the retentate generated by the engine system, comprising:
- removing the retentate contained in the engine exhaust system particulate filter;
- analyzing the physical or chemical properties of the retentate removed from the engine exhaust system particulate filter including detecting the presence in the retentate of the physical or chemical properties of a compound or element of the engine system or the engine exhaust system;
- and
- diagnosing the engine system based on the analysis and detection of the physical or chemical properties of the engine compound or element in the retentate.
