TWC-Used Cars, Modified CarsThe three-way catalytic converter is the most important off-board purification device installed in the automobile exhaust system. It can convert harmful gases such as CO, HC and NOx discharged from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. When the high-temperature automobile exhaust passes through the purification device, the purifier in the three-way catalytic converter will enhance the activity of the three gases CO, HC and NOx, prompting them to undergo certain oxidation-reduction chemical reactions, in which CO is oxidized to colorless and non-toxic carbon dioxide gas at high temperature, HC compounds are oxidized to water (H20) and carbon dioxide at high temperature, and NOx is reduced to nitrogen and oxygen. The three harmful gases are turned into harmless gases, so that the automobile exhaust can be purified.TWC-Motorcycle,General Purpose
Metal honeycomb catalyst is one of the most commonly used structures of three-way catalyst. As the most important external purification device installed in the exhaust system of motor vehicles, it can convert harmful gases such as CO, HC and NOx discharged from motor vehicle exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction. Catalysts are designed for motorcycles/general-purpose engines of various displacements to meet the emission regulations of different countries and regions.
