Abstract:
1. A method of recording the amount of time a particulate trap has been in service, comprising: collecting, with a controller, in-service data related to an operating parameter indicative of a length of time an engine has been operated; determining, based on the in-service data, a total length of time the engine has been used in service; communicating information related to the in-service data collected by the controller from the controller to a memory device associated with a particulate trap configured to remove at least some constituents of an exhaust flow from the engine through an exhaust system; updating usage data on the memory device, based on the communication with the controller, wherein the usage data is indicative of a total length of time the particulate trap has been used in service; and comparing the total length of time the particulate trap has been used in service to the total length of time the engine has been used in service.
