Product introduction
Premium catalytic converter for The Southeast Rhombus V3，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!
1.Definition and function of three-way catalytic converter
The three-way catalytic converter is an external purification device installed in the automobile exhaust system, which converts carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx) in the engine exhaust into harmless carbon dioxide (CO₂), water (H₂O) and nitrogen (N₂) through REDOX reaction, thereby reducing environmental pollution 136. The three-way catalytic converter of the V3 is usually located at the back of the exhaust manifold, between the front oxygen sensor and the rear oxygen sensor, ensuring that the high-temperature exhaust gas can effectively trigger the catalytic reaction.
2, structure and material
Core component
Support: Porous ceramic material that provides surface area to attach the catalyst.
Catalyst coating: Covering platinum (Pt), palladium (Pd), rhodium (Rh) and other precious metals to accelerate chemical reactions.
Housing: Double stainless steel with internal insulation to prevent heat loss and protect the internal structure.
Design feature
The three-way catalytic converter of Dongnan Ryuet V3 should be adapted to its engine displacement and exhaust system layout to ensure the balance between catalytic efficiency and exhaust back pressure to avoid power loss.
3, the working principle
High temperature catalysis
When the tail gas temperature reaches 300-500 ° C, the precious metal catalyst is activated and the gas is purified by the following reaction:
CO oxidation →CO₂;
HC oxidation →H₂O and CO₂;
NOx reduction →N₂ and O₂136.
Closed loop control
The front oxygen sensor monitors the oxygen content of the exhaust gas, feeds back to the ECU to adjust the air-fuel ratio, and the rear oxygen sensor detects the efficiency of the catalytic converter, and triggers the fault light if the data is abnormal.
4. Common faults and maintenance
Typical fault
Plugging: Carbon or lead poisoning leads to increased exhaust back pressure, resulting in decreased power and increased fuel consumption.
Carrier damage: Ceramic carrier due to bump or aging fragmentation, produce abnormal noise and reduce conversion efficiency.
Precious metal failure: long-term use of inferior fuel or high temperature leads to catalyst inactivation, exhaust emissions exceed the standard.
Maintenance suggestion
Regular cleaning: Use a special cleaning agent or oxalic acid soak every 30,000 kilometers to remove carbon deposits.
Avoid bumping: Slow down when passing through the pothole section to prevent the chassis impact from damaging the catalyst.
Use high-quality fuel: reduce sulfur, lead and other impurities on the catalyst toxicity.
5. Replacement and detection
Replacement cost
The original three-way catalytic converter contains precious metal coating, the price is higher (usually thousands of yuan), and the auxiliary parts cost is lower but the life is shorter.
Detection standard
Back pressure test: Measure exhaust resistance to determine whether it is blocked 5.
Temperature difference method: the outlet temperature of the catalytic converter should be 10%-25% higher than that of the entrance, otherwise the efficiency is insufficient.
Annual inspection requirements: Under the national six standard, the failure of the catalytic converter will directly lead to unqualified exhaust gas detection.
6, precautions
Anti-theft design: Precious metal coating may be the target of theft, it is recommended to install a protective cover.
Legal maintenance: Avoid dealing with the test by temporarily replacing the catalytic converter, which is illegal and polluting the environment.
