Catalytic Converter for HONDA CIVIC 2016-2021 2.0L FRONT 641584 EPA approved

The three-way catalytic purifier looks like an exhaust muffler, but actually functions as a muffler. The shell is made of high-temperature-resistant stainless steel, and the internal honeycomb channels are coated with catalysts. The catalyst components include rare earth metals such as platinum, palladium, and rhodium. When automobile exhaust gas passes through the channels of the purifier, carbon monoxide and hydrocarbons are evaporated. Under the action of the catalyst platinum and palladium, it reacts with oxygen in the air to produce harmless water and carbon dioxide, while nitrogen oxides are reduced to harmless oxygen and nitrogen under the action of the catalyst rhodium.
