Product introduction
Factory supply catalytic converters for Changan old Aotuo，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, exhaust emissions have been significantly optimized
Efficient conversion of harmful gases
Through the catalysis of platinum (Pt), rhodium (Rh), palladium (Pd) and other precious metals, the carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx) in the exhaust gas is converted into harmless carbon dioxide (CO₂), water (H₂O) and nitrogen (N₂), the emission of pollutants is reduced by about 90%, and the exhaust odor is significantly reduced.
If the old Aotuo car is not equipped with a catalytic converter, the installation can significantly improve environmental compliance, avoid the annual inspection failure or restriction due to excessive emissions.
Comply with environmental regulations
The old Aotuo models that are not equipped with catalytic converters in the early days (such as national one or lower emission standard models) can meet the current standards of national four and national five after installation, and adapt to more stringent environmental requirements.
2. Improved engine performance and fuel economy
Combustion efficiency improvement
The three-way catalyst and oxygen sensor work together: the front oxygen sensor detects the oxygen content and feeds back to the ECU, accurately adjusting the air-fuel ratio (ideal ratio 14.7:1), so that the combustion is more full and the dynamic response is more sensitive.
If the original catalytic converter fails or is missing, the engine may decrease power and increase fuel consumption due to the imbalance of air-fuel ratio, and the fuel economy can be increased by 5%-10% after replacement.
Avoid fault alarm and power loss
The rear oxygen sensor monitors the catalytic converter status and triggers the engine failure light if it fails. The installation of a qualified catalytic converter can eliminate the alarm and avoid the power attenuation caused by the increase of exhaust resistance.
3. Prevent failure and prolong the life of components
Reduce exhaust system problems
If the old Alto is not equipped with a catalytic converter for a long time, the particles in the exhaust gas may block the exhaust pipe or damage the oxygen sensor. After installation, it can reduce carbon accumulation and reduce the risk of clogging the exhaust system.
Avoid burning red or abnormal sound of exhaust pipe caused by direct discharge of high-temperature exhaust gas.
Extend the catalytic life
If used correctly (such as avoiding inferior fuel and regular cleaning), the catalytic life can reach 80,000-100,000 kilometers. When cleaning, it is necessary to preheat to 400-800°C, inject special cleaning agent and maintain high speed, which can remove harmful substances such as sulfur and phosphorus.
4, economic and maintenance suggestions
Reasonable selection of accessories
Low-cost catalytic converters (such as less than 600 yuan) may be due to insufficient precious metal content or structural defects resulting in poor purification effect, easy to block, and even lead to the risk of spontaneous combustion, it is recommended to choose authentic or original parts of more than 1500 yuan.
The auxiliary catalytic converter needs to be carefully selected, and some products with substandard quality may affect the annual inspection or engine performance.
Reduce long-term costs
Regular maintenance (such as cleaning carbon deposits and checking oxygen sensors) can reduce the frequency of replacement and save maintenance costs.
Compliance emissions increase the residual value of used cars to avoid depreciation due to environmental issues.
5. Precautions after installation
Run-in and use specifications
The new catalytic converter needs to be activated at high temperatures (above 250°C) and avoid short trips after installation to ensure full heating to the optimal operating temperature of 400-800°C.
Use unleaded gasoline to prevent precious metal catalyst poisoning failure.
Comprehensive troubleshooting
If the exhaust gas is still not up to standard after installation, check other engine problems (such as valve leakage, oxygen sensor damage, insufficient combustion, etc.).
Sum up
The addition of a three-way catalytic converter to the old Changan Aotuo can significantly improve environmental compliance, optimize engine performance and reduce failure rates. To ensure the effect, select genuine accessories, install them properly, and maintain them regularly. If the vehicle has no catalytic converter, it is recommended to give priority to the original factory or high-quality sub-factory products to avoid derivative problems caused by inferior parts.
