Product Description
The catalytic converter is the most important external cleaning device installed in the automotive exhaust system. It converts harmful gases such as CO, HC and NOx from automobile exhaust gas into carbon dioxide, water and nitrogen through oxidation and reduction. When high-temperature vehicle exhaust passes through the purification device, the catalytic converter enhances the activity of CO, HC and NOx to promote their oxidation-reduction chemical reaction.
