Exhaust gas treatment: clean engines mean better performance
The limit values for harmful emissions are becoming ever stricter. The ability to comply with these values requires not only fuel combustion that is as clean as possible but also a process of exhaust gas treatment. The nitrogen oxide emissions of a modern diesel are now 96% lower than those of a typical diesel from 1990. The SCR catalytic converter (Selective Catalytic Reduction) and Denoxtronic from Bosch further reduce the remaining nitrogen by more than 90%. It therefore comes as no surprise that, in some cities, the cleaned exhaust gases are cleaner than the ambient air.
