Product introduction
Exhaust manifold catalytic converter for Honda Acura，This product we use high-quality raw materials 409 stainless steel, and with high flow ceramic carrier, to help each car can purify exhaust gas, reduce fuel consumption, improve power, and extinguish engine failure lights!
The three-way Catalytic Converter (TWC) is the core component of the automobile exhaust gas treatment system, which is mainly used to convert the Three main harmful gases emitted by the internal combustion engine into harmless substances. Here are its key takeaways:
1. Core functions
Transformation of three pollutants:
Carbon monoxide (CO) → Carbon dioxide (CO₂)
Hydrocarbons (HC) → Water (H₂O) and carbon dioxide (CO₂)
Nitrogen Oxides (NOx) → Nitrogen (N₂) and Oxygen (O₂)
The three bodies are treated at the same time through oxidation and reduction reactions, so the name "ternary".
2. Catalyst material
Using precious metals as catalysts:
Platinum (Pt) and palladium (Pd) : promote oxidation reactions (conversion of CO and HC).
Rhodium (Rh) : promotes reduction reaction (breakdown of NOx).
The catalyst is coated on a honeycomb ceramic or metal support to increase the reaction contact area.
3. Working conditions
The air-fuel ratio should be close to the theoretical value (14.7:1), which is monitored in real time by the oxygen sensor and fed back to the ECU (driving computer) to adjust the fuel injection.
Need to reach high temperature (about 250°C above) in order to work efficiently, cold start efficiency is low.
4. Structure and materials
Carrier: high temperature resistant ceramic or metal, honeycomb structure design to reduce exhaust resistance.
Washcoat: Increases surface area and supports catalyst particles.
5. Application and advantages
Meet strict emission standards (such as national VI, Euro VI) to reduce smog and acid rain.
Modern gasoline vehicles are standard, and diesel vehicles need to cooperate with other technologies (such as SCR) due to differences in exhaust composition.
6. Limitations and maintenance
High cost: precious metal resources are scarce, and the catalytic converter accounts for a higher proportion of the cost of the vehicle.
Sensitive issues:
Lead poisoning: Leaded gasoline can coat the surface of the catalyst and cause failure.
Sulfur effect: High sulfur content of fuel reduces catalytic efficiency.
Life: The design life is usually 8-100,000 kilometers, and it needs to be replaced after aging.
7. Relevant technology
OBD system: Monitor catalytic converter efficiency and trigger failure lights (such as MIL lights) when abnormal.
GPF/DPF: Used in conjunction with three-way catalysis, a gasoline vehicle particle catcher (GPF) or diesel vehicle particle filter (DPF) further reduces particulate matter emissions.
