In order to meet the stringent emission regulations of diesel and gas engines we continuously improved our exhaust after treatment systems. The options for the various applications are highlighted in the following.
Today exhaust gas of diesel and gas engines is typically treated with “Three Way Catalysts” (TWC). The catalyst converts the pollutants CO, NOX and Hydrocarbons into harmless compounds like CO2, H2O and N2 by chemical reactions. Lambda-Sensors control the air fuel ratio of the engine and catalyst performance in order to get the best possible conversion of the pollutants.
