📌Following are the Types of Catalytic Converters🚘:
📌1. 2-way Catalytic Converter🚘🚘
The two-way catalytic converter was present on vehicles in the United States until 1981. They only have oxidation catalysts, which help change carbon monoxide to carbon dioxide. Hydrocarbons (which are unburned and partially burned fuel) are changed to carbon dioxide and water.
📌2. 3-way Catalytic Converter🚘🚘
The three-way catalytic converter currently permits the most efficient, safest, and most reliable form of emission control in petrol engines. As the name implies, the three-way catalytic converter converts three pollutants: hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) into less harmful gases.
📌3. Diesel Oxidation Catalytic Converter🚘🚘
A diesel oxidation catalyst (DOC) is an after-treatment component that is designed to convert carbon monoxide (CO) and hydrocarbons into carbon dioxide (CO2) and water. The device is used on all our EU Stage IV/U.S. EPA Tier 4 Final products – from the 400F through to the 1206F.
📌4. EGR System🚘🚘
EGR system and catalytic converter are used to reduce the exhaust emission from an IC engine. The catalytic converter reduces efficiently the emission of HC, CO, PM, etc. whereas the EGR system is a very effective technique for reducing NOX emission. The formation of NOx is almost absent at temperatures below 2000K.
📌5. DPF🚘🚘
A DPF is simply a large filter made from heat-proof materials that trap particles of soot to prevent them from escaping from the exhaust. It has periodic automated cleaning cycles where it self-cleans. A catalytic convertor uses a chemical reaction to turn toxic gasses into less toxic gasses.
📌6. SCR
Selective catalytic reduction means of converting nitrogen oxides, also referred to as NO ₓ with the aid of a catalyst into diatomic nitrogen, and water. A reductant, typically anhydrous ammonia, aqueous ammonia, or a urea solution, is added to a stream of flue or exhaust gas and is reacted onto a catalyst.
