APPARATUS, SYSTEM, AND METHOD FOR DETECTING CRACKING WITHIN AN AFTERTREATMENT DEVICE

摘要

An apparatus, system, and method are disclosed for detecting cracking in a particulate filter. The method may include providing an apparatus comprising an aftertreatment device 106 with a substrate 302 and a substrate surface 304, a conductive material forming a conduction path bonded to the surface of the substrate surface 304, and access points 108 configured to allow a resistance measurement of the conduction path 306. The method may include measuring the resistance of the conduction path 306, and determining if one or more cracks have occurred on the substrate surface 304 based on the resistance measurement. The method may further include labeling the degradation level of the aftertreatment device 106 based on the indicated amount of cracking, and replacing the aftertreatment device 106 with an equivalent aftertreatment device, based on the degradation level, after a service event.
