Abstract
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 generates a control signal to initiate induction heating of the emission control device. An electromagnetic field generator responds to the control signal by generating a power signal applied to a coil to cause the induction heating of the emission control device, wherein a frequency of the power signal is adjusted to control a power transferred to the coil.
Claims19
An emission control system comprising:
- an emission control device having a plurality of passages to facilitate emission control of an exhaust gas from a vehicle engine;
- a controller, that generates a control signal to initiate induction heating of the emission control device;
- and
- an electromagnetic field generator having a coil, wherein the electromagnetic field generator responds to the control signal by generating a power signal applied to the coil to cause the induction heating of the emission control device, wherein a frequency of the power signal is adjusted to control a power transferred to the coil;
- wherein the controller monitors a temperature of the electromagnetic field generator and wherein the controller generates the control signal to discontinue induction heating of the emission control device when the temperature of the electromagnetic field generator exceeds a temperature threshold.
A method comprising:
- generating, via a controller, a control signal to initiate induction heating of an emission control device;
- generating, in response to the control signal and via an electromagnetic field generator that includes a coil, a power signal, wherein the power signal is applied to the coil to cause the induction heating of the emission control device;
- adjusting a frequency of the power signal, to control a power transferred to the coil;
- and
- monitoring, via the controller, a temperature of the electromagnetic field generator and wherein the controller generates the control signal to discontinue induction heating of the emission control device when the temperature of the electromagnetic field generator exceeds a temperature threshold.
