2008-2010 Chrysler Town & Country Dodge Grand Caravan 3.3L Catalytic Converter

The specific working process of the three-way catalytic converter is: when high-temperature automobile exhaust passes through the purification device, the catalyst in the three-way catalytic converter will enhance the activity of the three gases of carbon monoxide, hydrocarbons and nitrogen oxides, causing them to evaporate on the surface of the catalytic converter. Carry out certain oxidation-reduction chemical reactions: carbon monoxide is oxidized to colorless, non-toxic carbon dioxide at high temperatures, hydrocarbons are oxidized to water and carbon dioxide at high temperatures, and nitrogen oxides are reduced to nitrogen and oxygen. In this way, the three harmful gases are turned into non-toxic and harmless common gases, and the car exhaust is purified in this way.
