Three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. The following are specific introductions: Functions: The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It can convert harmful gases such as CO, HC, and NOx emitted by automobile exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction. Design Principle: When high-temperature exhaust gas passes through the purification treatment device, the purifying agent in the three-way catalytic converter will enhance the activity of the three gases, CO, HC, and NOx, promoting certain oxidation-reduction chemical reactions. Among them, CO is oxidized at high temperatures into colorless and non-toxic carbon dioxide gas; NOx is converted into nitrogen and oxygen. The three harmful substances are transformed into non-toxic gases, thereby purifying the exhaust emissions.
