Abstract:

A radio frequency system and method for monitoring an engine-out exhaust emission constituent. The system comprises a housing containing the emission constituent, one or more radio frequency sensors extending into the housing and transmitting and receiving radio frequency signals, and a control unit for controlling the radio frequency signals and monitoring changes in the emission constituent based on changes in one or more parameters of the radio frequency signals. In one embodiment, the control unit measures a rate of change in one or more of the parameters of the radio frequency signals for monitoring a rate of change of the emission constituent including for example the emission rate, accumulation rate, and/or depletion rate of the emission constituent.

Abstract:

A radio frequency sensing, control, and particulate matter diagnostics network and system and method and, more specifically, a radio frequency particulate filter diagnostics system comprising a housing including an inlet connected to a source of particulate matter, a particulate filter in the housing and adapted for filtering the particulate matter, and a radio frequency sensor adapted to detect conditions of abnormal particulate filter or system operation and including at least one radio frequency probe configured to be in contact with the housing for the particulate filter housing and adapted to receive radio frequency signals and a radio frequency control unit in communication with the radio frequency probe.

H04L 29/08

Abstract:

An RF emissions sensing system including RF sensors for transmitting/receiving RF signals to and from engine system emission control components, a control unit for collecting/processing information from the RF signals and controlling system outputs. The RF emissions sensing system includes a means and method for the characterization of the operating state and/or performance of the engine system including the use of time-based or historical RF information and system outputs, the application/monitoring of pertubations to the engine system, the comparison of system outputs to baseline/reference system outputs, the periodic activation of the engine system after shut-down, the monitoring of changes in the electric or temperature profiles of the engine system emission control components, and communication with external sources to improve the accuracy of the system outputs.
