Three catalytic converters, is the most important cleaning device is installed in the exhaust system of the machine, it can be automobile exhaust CO, HC and NOx and other harmful gases by oxidation and reduction into harmless carbon dioxide, water and nitrogen. When the temperature of the automobile exhaust purification device through the purifying agent, three waycatalytic in CO, HC and NOx will enhance the activity of three kinds of gas, the certain redox reaction, in which CO high temperature oxidation of carbon dioxide gas to become colorless, non-toxic; HC compounds in high temperature oxidation water and carbon dioxide (H20); NOx reduction of nitrogen and oxygen. Three harmful gases into harmless gas, so that the car exhaust to purify.
