The invention relates to an emission control system with resonant frequency measurement and methods for use therewith. Aspects of the subject disclosure may include, for example, an emission control system that includes an emission control device having a plurality of passages to facilitate emission control of an exhaust gas from a vehicle engine. A controller determines the resonant frequency ofa coil and generates a control signal based on the resonant frequency of the coil to initiate induction heating of the emission control device. An AC source responds to the control signal by generating a power signal applied to the coil to cause the induction heating of the emission control device. 本发明涉及利用谐振频率测量的排放控制系统和与其一起使用的方法。主题的各方面可以包括例如一种排放控制系统，该排放控制系统包括排放控制装置，该排放控制装置具有多个通路以促进来自引擎的废气的排放控制。控制器确定线圈的谐振频率，并且基于线圈的谐振频率来产生控制排放控制装置的感应加热的控制信号。交流(AC)源通过对线圈产生功率信号以促进经由线圈对排放控制装置的感应加热来对控制信号做出响应。
