Does Every Car Have a Three-Way Catalytic Converter?

[StKing]

Not all cars are equipped with a three-way catalytic converter. In earlier years, vehicles produced in China that did not meet the National II emission standards were not fitted with three-way catalytic converters. Relevant information about the three-way catalytic converter is as follows: Introduction 1: The three-way catalytic converter is the most important external purification device installed in a car's exhaust system. It converts harmful gases such as CO (carbon monoxide), HC (hydrocarbons), and NOx (nitrogen oxides) emitted from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Introduction 2: Because this converter can simultaneously transform the three main harmful substances in exhaust gases into harmless substances, it is called a three-way catalytic converter.
