ABSTRACT:
This invention relates to a method for controlling the conductance of heated structures used to initiate faster light-off in emission control systems such as used for automotive catalytic converters, diesel particulate filters and industrial stacks and other applications in which the exhaust gas stream temperature is too low to initiate fast light-off. The invention also relates to a method for minimizing the amount of conductive material used for making such structures.
