Abstract
In a method for operating an internal combustion engine of a motor vehicle, exhaust gas from the internal combustion engine is fed to a particulate filter of the motor vehicle. Until a predetermined filtration rate of the particulate filter is reached, a temporary interruption of a fuel supply to the internal combustion engine is prevented in an overrun mode of the motor vehicle if a temperature of the exhaust gas in the particulate filter is greater than a predetermined threshold value of the temperature. An arrangement of the particulate filter in an exhaust system of the motor vehicle is also described.
