How are Two-Way Converters Different from Three-Way Converters?
The primary difference between two-way and three-way converters lies in the pollutants they target. As mentioned earlier, two-way converters focus on CO and HC, whereas three-way converters also reduce NOx emissions. This makes three-way converters more comprehensive in addressing the range of pollutants emitted by vehicles. However, two-way converters are still widely used in applications where NOx emissions are less of a concern, such as in certain types of engines and older vehicles.
