Three-way catalyst and carrier
National 6/Euro 6 emission reduction solution
-
honeycomb Ceramic carrier (cordierite & Silicon Carbide)
- Material properties: low thermal expansion coefficient (1.5×10⁶/°C), high melting point (1450°C), suitable for frequent start and stop conditions of urban roads.
- Application scenarios: Japanese/European family cars, hybrid models (such as Toyota Prius, Volkswagen Golf).
-
Metal carrier (iron-chromium-aluminum alloy)
- Material properties: high mechanical strength (vibration resistance increased by 50%), superior thermal conductivity than ceramic, suitable for diesel vehicles and high performance vehicles (such as BMW M series, Mercedes AMG).
- Technical breakthrough: laser welding process reduces carrier deformation, hole uniformity error is less than 2%.

Product application scenarios and solutions
- Passenger car exhaust upgrade: old models (below national 4) replace catalytic converters and pass the annual inspection emission test.
- Emission reduction plan for commercial vehicles: diesel trucks are equipped with DOC+SCR system to meet the national 6 emission limits.
- Non-road machinery modification: construction machinery (excavator, forklift) is equipped with catalytic converters to meet the national standard IV for non-road machinery.

Does the failure of the catalyst lead to increased fuel consumption?
Yes! Carrier blockage will increase the exhaust back pressure, engine ECU forced enrichment of fuel injection, fuel consumption may rise 10%-20%.

How to judge the quality of precious metal coating?
Three quick identification methods:
1. Check the ICP-MS precious metal content test report provided by the supplier;
2. Use a magnet to test the carrier (high quality ceramic carrier is non-magnetic, low quality iron impurities will be adsorbed);
3. Check the uniformity of the coating (no mottled reflection points should be seen under strong light). -

How to choose the carrier type for modified vehicles?
Turbocharged models are recommended to use iron-chromium-aluminum metal carrier, which can withstand high exhaust temperature with 1000°C heat resistance, and the strength of honeycomb structure is 40% higher than that of ceramic carrier.

Is it necessary to install a new catalytic converter professionally?
You must choose the model that is compatible with the original vehicle displacement, ECU system and oxygen sensor. It is recommended to match the VIN code accurately.
