Converter overtemperature protection system and method

Image Number 3 for United States Patent #5138833.

When an incipient overtemperature condition of a catalytic converter of a vehicle is sensed, a cylinder of the vehicle engine having combustion conditions giving rise to the overtemperature condition is identified by selectively disabling fuel delivery to each of the cylinders of the engine in turn and monitoring the response of the converter temperature. If the disabling of the fuel to a particular cylinder results in recovery from the incipient overtemperature condition, fuel to that cylinder is maintained disabled to provide overtemperature protection of the converter.
