Abstract (en)
[origin: WO0149994A1] The invention relates to an internal combustion engine (1), in particular for a motor vehicle, which is provided with a storage catalyst (12'). Said storage catalyst can be fed with and can discharge nitrous oxides. A temperature sensor (13, 14) is provided for measuring the temperature of the exhaust gas that flows through the storage catalyst (12') and/or for measuring the temperature of the storage catalyst (12'). The measured temperature is compared with a threshold value, using a control device (18).
