摘要： A particulate sensing system for a particulate trap including a radio frequency transmit circuit and a radio frequency receive circuit is disclosed. The transmit circuit may include a wideband signal generator configured to produce a wideband radio frequency signal and a wideband radio frequency amplifier, coupled to the wideband signal generator. The transmit circuit may include a transmit antenna coupled to the wideband radio frequency amplifier and configured to propagate the wideband radio frequency signal through a filter medium. The receive circuit may include a receive antenna configured to receive the wideband radio frequency signal that has been propagated through the filter medium, and a bandpass filter coupled to the receive antenna and configured to limit a frequency range of the received wideband radio frequency signal. The receive circuit may include a radio frequency power sensing device coupled to the band pass filter and configured to sense a power level of the received wideband radio frequency signal and configured to output a direct current voltage proportional to the total power received across an operating frequency range of the radio frequency power sensing device.

摘要： A particulate trap regeneration system is provided, which may include a particulate trap having a filter medium configured to remove one or more types of particulate matter from an exhaust flow of an engine and a regeneration device configured to reduce an amount of particulate matter in the particulate trap, as well as a radio frequency-based particulate loading monitoring system configured to determine an amount of particulate matter trapped by the filter medium. The particulate loading monitoring system may include at least one radio frequency transmitting probe configured to transmit radio frequency signals of predetermined magnitude and predetermined frequency toward the filter medium and at least one radio frequency receiving probe configured to receive and measure the magnitude of received radio frequency signals that pass through the filter medium. Further, the system may include a temperature sensing device configured to take a temperature measurement indicative of a temperature of the particulate trap at the time the radio signals are received by the receiving probe and a controller, which may be configured to determine, based on the measured magnitude of received radio frequency signals, a particulate loading value indicative of the amount of particulate matter trapped in the filter medium. The controller may also be configured to perform a temperature compensation including modifying, based on the temperature measurement, at least one of the following: the measured magnitude of the received radio frequency signals that pass through the filter medium or the particulate loading value.

摘要： An engine assembly may include an internal combustion engine configured to combust fuel. The combustion of fuel may produce exhaust and sound waves that may be directed into an exhaust line. A particulate filter may be operatively coupled to the exhaust line, and the particulate filter may be configured to filter the exhaust. The engine assembly may also include a sensor package operatively coupled to the exhaust line. At least a portion of the sensor package may extend into the exhaust line at a location downstream from the particulate filter. The sensor package may be configured to monitor the sound waves passing through the particulate filter and to produce an electrical signal indicative of the intensity of the sound waves.
