Product introduction
Premium catalytic converter for Chang 'an Shenqi old model，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 gas purification and environmental protection standards
The three-way catalytic converter catalyzes the reaction through the internal precious metal coating such as platinum (Pt), palladium (Pd), rhodium (Rh), etc., converting carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx) in the tail gas into carbon dioxide (CO₂), water (H₂O) and nitrogen (N₂), significantly reducing pollutant emissions. After installation, it can ensure that the exhaust gas of the vehicle meets the national standards, and avoid the risk of failing the annual inspection or fines due to excessive emissions.
2. Improve engine performance
Optimize combustion efficiency: The three-way catalytic converter is linked with the front oxygen sensor to monitor the exhaust oxygen content in real time and feed back to the ECU, adjust the air-fuel ratio to the ideal value (14.7:1), reduce carbon deposition, thereby reducing fuel consumption and increasing power output.
Avoid exhaust clogging: If it is not installed or the catalytic converter fails, the increase of exhaust resistance may cause the engine power to drop, the acceleration is weak, and even trigger the fault light.
3. Extend the life of exhaust system
Reduced mechanical impact: The three-way catalytic converter is located behind the exhaust manifold (exhaust pipe head section), and its honeycomb ceramic carrier absorbs exhaust pressure fluctuations to reduce impact on subsequent components such as the muffler.
Prevent high temperature damage: the normal working temperature of the catalytic converter should be maintained at 400-800 °C, and the reasonable installation position and structural design can avoid the carrier cracking or coating falling off due to local overheating.
4. Troubleshoot common faults and provide maintenance suggestions
Blockage problem: The old model due to long-term use or poor oil products, easy to lead to blockage of the three-way catalytic converter, manifested as increased fuel consumption, exhaust odor or power decline. It can be cleaned regularly with oxalic acid solution immersion or professional equipment high temperature cleaning, but the use of inferior fuel should be avoided.
Failure performance: If the data of the oxygen sensor before and after are consistent, it indicates that the catalyst has failed and needs to be replaced in time to avoid affecting the engine operation.
5. Economic and legal risk avoidance
Avoid high maintenance costs: the three-way catalytic converter contains precious metals, the replacement cost is high (the auxiliary parts are about 800-1200 yuan, the original parts are more expensive), and regular maintenance can extend its life.
Compliance protection: If the old vehicle is not installed or the catalytic converter is damaged, it may face the risk of failing the annual inspection, fines and even vehicle restrictions.
