ABSTRACT:
An apparatus for reducing the amount of electrical power needed to attain light-off of a catalytic converter, particularly a catalytic converter for internal combustion engines. In addition to a resistance-heated catalytic converter, means are provided for varying the air/fuel ratio in the exhaust gas system for the purpose of reducing the ignition temperature of the exhaust gas stream, thereby further reducing the electrical energy required to attain light-off during cold-start.
