There are three main types of catalytic converters:
Two-Way Catalytic Converters: These are used in older vehicles and primarily target CO and HC emissions, converting them into CO2 and water (H2O). Three-Way Catalytic Converters: These are commonly used in modern vehicles and address CO, HC, and NOx simultaneously, converting them into CO2, H2O, and nitrogen (N2). Diesel Oxidation Catalysts: Specifically designed for diesel engines, these converters target CO and HC, and also reduce particulate matter to some extent.
