What are the types of three-way catalytic converters?

[MilesRose]

The types of three-way catalytic converters are DOC, DPF, SCR, and ASC. Below are the scenarios regarding whether a three-way catalytic converter can be repaired: 1. Damage: If the three-way catalytic converter is damaged, such as being broken or deformed, it cannot be repaired and must be replaced directly. 2. Clogging: If it is only clogged, its performance can be restored through cleaning, but severe clogging still requires replacement. Below is additional information about the three-way catalytic converter: 1. Device: The three-way catalytic converter is the most crucial external purification device installed in a vehicle's exhaust system. 2. Exhaust gases: It converts harmful gases emitted from vehicle exhaust, such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx), into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. 3. Origin: This type of catalytic converter can transform three common harmful substances in exhaust gases into harmless substances, hence the name 'three-way'.
