Method for operating a combustion engine with low emission of pollutants and corresponding combustion engine

摘要

The method involves guiding exhaust gas produced from a combustion engine (2) in a shift operation by an emission reduction device (9) for catalyzing unit (19). An exhaust-gas system (3) is provided with the catalyzing unit and the emission reduction device. The exhaust gas is guided from combustion engine to catalyzing unit in stoichiometric operation partly by a bypass (8) parallelly switched to emission reduction device. An independent claim is included for a combustion engine, particularly used for a method.
