Microwave system for regenerating diesel particulate filter comprises regulator module adjusting operation of microwave source based on power level of reflected microwave signals and predetermined power threshold

摘要

A microwave system comprises a sampling device that samples at least one power level of reflected microwave signals from a diesel particulate filter and a power level within the diesel particulate filter cavity that is indicative of microwave power reflected from the cavity back to the microwave source; and a regulator module that communicates with the microwave source and the sampling device and that adjusts operation of the microwave source based on the power level of the reflected microwave signals and a predetermined power threshold.
