Patent Images
1. An emission control system comprising:
- an emission control device having a plurality of passages to facilitate emission control of a vehicle engine, the emission control device having a substrate and pins of a plurality of differing lengths;
a controller, that generates a control signal to initiate induction heating of the emission control device; and
an electromagnetic field generator that responds to the control signal by generating a power signal applied to one or more coils to cause the induction heating of the pins of the emission control device, wherein the plurality of differing lengths of the pins cause a first region of the emission control device to heat faster than a second region of the emission control device.

Abstract
In various embodiments, an electromagnetic field generator generates one or more power signals applied to one or more coils to cause the induction heating of the pins of the emission control device, The pins can have a plurality of differing lengths, and the heating of the pins can cause a first region of the emission control device to heat faster than a second region of the emission control device.
