SYSTEMS AND METHODS FOR USING TRANSPORT TIME TO ESTIMATE ENGINE AFTERTREATMENT SYSTEM CHARACTERISTICS

A system includes a controller that has a processor. The processor is configured to receive a first signal from a first sensor indicative of a first exhaust measurement, wherein the first sensor is disposed at a catalytic converter system inlet of a catalytic converter system. The processor is furth...

Beschreibung
Zusammenfassung:	A system includes a controller that has a processor. The processor is configured to receive a first signal from a first sensor indicative of a first exhaust measurement, wherein the first sensor is disposed at a catalytic converter system inlet of a catalytic converter system. The processor is further configured to derive one or more of an estimated length, estimated volume, or estimated transport delay of an exhaust conduit based on the first signal, wherein a first end of the exhaust conduit is connected to an engine outlet of a engine, and a second end of the exhaust conduit is connected to the catalytic converter system inlet; and to apply the one or more of estimated length, estimated volume, or estimated transport delay of the exhaust conduit during control of the engine.
