Method of protecting a catalytic converter |
摘要 |
The invention is directed to a method for protecting a catalytic converter in the exhaust gas of an internal combustion engine in a starting operation of the engine. An index is formed for the quantity of an air/fuel mixture which will first react exothermally in the catalytic converter downstream of the engine. The index is compared to a predetermined threshold value and fuel metering is cut off when the threshold value is exceeded.
