Euro 4 Direct Fit toyota corolla catalytic converter

The Three way catalytic converter is a purification device of the automobile exhaust pipe, which can convert harmful gases such as CO, HC and NOx in the exhaust gas into harmless carbon dioxide, water and nitrogen. When the high-temperature exhaust gas through the purification device, the purification agent in the three-way catalytic converter will enhance the activity of CO, HC and NOx three gases, and promote it to carry out a certain oxidation-reduction chemical reaction, in which CO oxidizes into a colorless, non-toxic carbon dioxide gas at high temperature; HC compounds oxidize to water (H2O) and carbon dioxide at high temperatures; NOx is reduced to nitrogen and oxygen. Three harmful gases become harmless gases, so that car exhaust can be purified The appearance of theDirect- Fit Three Way Catalytic is similar to the muffler, the outside is made of double-layer stainless steel, and the inside is equipped with a honeycomb cleaning agent, which is composed of a carrier and a cataly…
