Exhaust-gas treatment – economical and clean

As early as 1970 the introduction of obligatory emission threshold values based on strong traffic growth led to considerably stricter legislation. The Euro 5 standard is intended to introduce even stricter exhaust-gas regulations from 2009 onwards. In order to keep to these ever-stricter exhaust-gas emission values it is necessary not only to burn fuel as cleanly as possible but also to effectively treat exhaust gases.

The problem: reducing the production of nitrous oxides leads to an increase in fuel consumption and a rise in particulate formation.

The solution for economical and, at the same time, clean driving is the SCR (Selective Catalytic Reduction) process. Here a reduction agent is sprayed into the exhaust-gas upstream of the SCR catalytic converter. This transforms the nitrous oxides contained in the exhaust-gas into harmless substances.

The SCR catalytic converter system can be adapted for installation in a wide variety of vehicles – on its own or in combination with a particulate filter.
