Automotive Exhaust Catalytic Converter

The three-way catalyst is the most important external purification device in the automotive exhaust system. It converts CO (carbon monoxide), HC (hydrocarbons), and NOx (nitrogen oxides) in the exhaust gas into harmless carbon dioxide, water, and nitrogen through oxidation-reduction reactions, with a purification efficiency of over 90%. It is mainly used in cars and other small gasoline engine general equipment.
