  • Catalytic converter decontamination method
    Patent number: 5974790
    Abstract: A method for restoring exhaust purifying capability of a sulfur contaminated catalytic converter of an internal combustion engine. Catalytic converter efficiency is measured with a first exhaust gas oxygen sensor positioned upstream of the catalytic converter and a second exhaust gas oxygen sensor positioned downstream of the catalytic converter. When catalytic converter efficiency falls below a desired level, catalytic converter temperature is elevated and the engine is operated to produce a rich exhaust gas mixture to reduce the sulfur contamination. Then, to further reduce the sulfur contamination, the engine is operated to produce a lean exhaust mixture.
    Type: Grant
    Filed: March 5, 1998
    Date of Patent: November 2, 1999
