Document Type and Number:
Japanese Patent JPH10502428
Kind Code:
A
Abstract:
This invention is directed to a system for monitoring the efficiency of a catalyst employed to convert exhaust gases containing carbon monoxide, hydrocarbons and nitrogen oxides, e.g., those generated by an internal combustion engine such as in an automobile. The system comprises a thin-film resistive device and an electrical circuit connected to said thin-film resistive device capable of determining a change in the electrical resistance of a electrically conductive material provided in the device, the electrical resistance being subject to change during conversion of said exhaust gases over the catalyst.
