Abstract
A method for controlling temperature of a catalytic converter in an automobile exhaust system is disclosed. The method includes establishing a reference temperature for the catalytic converter, distributing a stream of exhaust gases through the catalytic converter, obtaining a measured temperature of the catalytic converter and converting thermal energy from the stream of exhaust gases into electrical energy when the measured temperature exceeds the reference temperature. An apparatus for controlling temperature of a catalytic converter in an automobile exhaust system is also disclosed.
