ABSTRACT:
The invention is directed to a method for interrupting fuel metered to an engine during overrun operation. The engine is equipped with a catalytic converter and the method includes the steps of: determining a criterion for the temperature of the catalytic converter; checking to determine if the criterion satisfies a condition for the temperature of the catalytic converter which is characteristic for a high temperature of the catalytic converter; and, interrupting the metering of fuel to the engine when the condition is not satisfied.
