<p>A process is disclosed for operating an internal combustion engine (3) with less pollutant emissions by subjecting its exhaust gas during its operation to a subsequent electric treatment for converting the pollutants emitted, the emission curve of which is measured. In order to improve a process having the above features in such a way that the desired reduction of pollutant emissions by the internal combustion engine be achieved during its whole operation, while avoiding the need to expand the electric system (5, 61, 62) of the internal combustion engine in a disproportionate and therefore costly manner, the subsequent electric treatment (1) of the exhaust fumes is carried out only during that part of the engine operation during which emission peaks occur.</p> |
