Catalytic converters

Two-stage catalytic converters were introduced in 1975 to control carbon monoxide and hydrocarbon emissions. Soon, a third stage was added to clean nitrogen oxides in the exhaust gas.

The light must go through all the cells of honeycomb of a Three-Way Catalyst, in order to guarantee the product quality.

BASF Three-Way Catalyst converts the three most important substances (hydrocarbons, carbon monoxide and oxides of nitrogen) of the exhaust system almost completely into carbon dioxide, nitrogen and water.

Catalyst testing: computer programs analyze the emission values under near-service conditions.

As of 1986 and 1996 in Western Europe and Hungary respectively, cars equipped with a catalyc converter are allowed to market and sell. Today, vehicles without a catalysator are prohibited from circulating in the German cities and towns.

Catalytic converters function by causing a series of chemical reactions to occur around the metal, usually platinum catalyst. Nitrogen oxides are converted into nitrogen and oxygen gases, carbon monoxide is converted into carbon dioxide, and the unburned hydrocarbons are converted to water and carbon dioxide.
