Three-way catalytic converters
Three-way catalytic converters (TWC) are used in engines with a lambda value of 1 (no excess oxygen). Carbon monoxide and hydrocarbons are oxidized and nitrogen oxides are reduced in the process.
The basis of a three-way catalytic converter are Very thin, high-temperature stable foils made of heat-resistant alloys. A special winding of the films gives the catalyst carrier a honeycomb structure. A special coating containing precious metals is applied to the wound metal foils to reliably reduce pollutants.
The Emission Partner three-way catalytic converters are designed for high conversion performance of nitrogen oxides and carbon monoxide, as well as long-term stability.
All our TWC catalytic converters are also produced 100% in-house. In cooperation with the best measuring institutes in Germany, we offer you reliable compliance with the emission limits and also prepare you optimally for the measurement date.

General information on catalytic converters
At Emission Partner, we support you with the right catalytic converter for your exhaust system and help you to reduce your emissions. The task of a catalytic converter is to minimize pollutant emissions.
The catalysts are used in a variety of ways for the oxidation and reduction of gaseous pollutants. They are mainly used in combustion engines, gas turbines, boiler systems and special industrial applications.
Our oxidation catalysts are used for excess oxygen (lean-burn engines). If your system does not have an excess of oxygen availablewe install TWC (three-way) catalytic converters.
If NOx emissions also need to be reduced, this can only be achieved with SCR catalytic converters in systems with excess oxygen. These reduce NOx gases in accordance with the current requirements of the 44th BImSchV.
Catalysts with a honeycomb structure are created in order to realize the conversion rate of the pollutants in the most compact installation space possible. This is manufactured either as a coated metal structure (matrix) or from a ceramic (stones).
The Osurface of the catalysts is essentially determined by the cellularity of the matrix. The standard cell size is 200 cpsi (number of cells per inch² – corresponds to approx. 2.54 cm x 2.54 cm). In the case of full extrudates (ceramics), however, the cellularity is usually below 100 cpsi for production reasons and usually 300 cpsi for special applications (TWC).
The cellularity and design of the catalytic converters (diameter and depth) define the exhaust back pressure and the conversion rate of the system. For this reason, an analysis of the installation situation and general conditions is absolutely essential to ensure the optimum design of the system.
