ABSTRACT:
There is provided an electrically heatable catalytic converter insert for insertion in a current internal combustion engine exhaust line. The device described includes a housing and a polycellular corrugated thin metal foil monolith disposed therein, and having a central core. The monolith includes a noble metal catalyst disposed of the inner surface of the cells. There are also provided a positive terminal and a negative terminal for attachment to a voltage source. The positive terminal is attached to the central core, and the negative terminal is attached to the housing, the foil providing a heatable resistance member enabling heating of the device by electrical power. The positive and negative terminals are electrically insulated from each other and each has a radially projecting arm for attachment of cables from a voltage source.
