ABSTRACT:
The invention relates to a method for optimizing exhaust quality of a combustion system, especially an internal combustion engine, wherein measured pollutant quantities in the exhaust are used to regulate the combustion system. According to the invention, the quantities of at least two pollutant components in the exhaust are measured using sensors, and a weighted composite signal is determined based on the measured quantities. This weighted composite signal is then set to a minimum by controlling an operating parameter that influences the exhaust composition. Such minimization can be performed continuously and sequentially as needed for a plurality of operating parameters that influence the exhaust composition.
