Factory supply catalytic converters for Changan Eurasia

Product introduction

Factory supply catalytic converters for Changan Eurasia，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, the core loading effect

High efficiency tail gas purification

Through the REDOX reaction, the CO (carbon monoxide), HC (hydrocarbons) and NOx (nitrogen oxides) in the tail gas are converted into harmless CO₂ (carbon dioxide), H₂O (water) and N₂ (nitrogen), and the conversion efficiency can reach more than 90%. The surface of the core honeycomb ceramic carrier is sprayed with platinum, palladium, rhodium and other precious metal catalysts, which can accelerate the chemical reaction at high temperature and significantly reduce the emission of pollutants.

Power and fuel economy optimization

Reduce exhaust resistance: A normal working three-way catalytic converter can keep the exhaust system unimpeded to avoid power drop and fuel consumption increase due to blockage. If the catalytic converter is blocked, the engine exhaust pressure increases, the power response is sluggish, and the fuel consumption may increase by 10%-15%.

High-flow catalytic converter adaptation: Partially modified high-flow three-way catalytic converter (mesh number 200-400 mesh, larger aperture) can reduce exhaust resistance, improve engine low-torque performance, especially suitable for ECU vehicles, power increase by about 20%.

Emission compliance assurance

The installation of a compliant three-way catalytic converter is a necessary condition for meeting the national 6B emission standards. If the catalytic converter fails or is stolen (such as the case of illegal replacement points), the vehicle exhaust emissions will exceed the standard, resulting in unqualified annual inspection, and even face fines.

2. Actual loading performance

Stability and durability

Corrosion resistant design: The shell is made of high temperature resistant metal material, and the internal honeycomb ceramic carrier is fixed by shock absorbing layer to avoid fragmentation caused by vibration or high temperature.

Life cycle: Normal service life of about 100,000 kilometers, if regular cleaning (such as every 10,000 kilometers using oxalic acid or bottle cleaning), can be extended to more than 150,000 kilometers.

Fault and maintenance impact

Congestion problem: Urban congestion road conditions can easily lead to carbon deposition, resulting in poor exhaust, power drop, cold start odor, etc. The catalytic efficiency should be monitored by oxygen sensors and cleaned or replaced in time.

Anti-theft needs: catalysts contain precious metals, easy to become the target of theft, it is recommended to install a protective cover or park in the monitoring area.

Compatibility of oil and driving habits

The use of low-grade gasoline or long-term short-distance driving will accelerate carbon deposition generation, it is recommended to regularly run at high speed to promote carbon deposition combustion, and choose high-quality fuel from regular gas stations.

3, compare the advantages of ordinary catalytic converters

Although Changan Auchan's original three-way catalytic converter is not clearly marked as a high-flow model, users can upgrade to a high-flow catalytic converter to optimize performance:

Larger aperture (fewer mesh) reduces the risk of clogging and is suitable for frequent low-speed driving environments.

Highly efficient catalysts (such as lanthanum and other non-precious metal materials), lower cost and stable catalytic activity.

Heat dissipation and noise reduction: Aluminum foil layer reduces noise and enhances heat dissipation performance.

4. Summary

The loading effect of Changan Auchan three-way catalytic converter is comprehensive performance of environmental protection standards, power stability, maintenance costs controllable. Its core value is to protect the environment through efficient exhaust gas purification, while taking into account vehicle performance and economy. Users should pay attention to regular maintenance (such as cleaning, monitoring oxygen sensor data) to avoid derivative problems caused by blockage or failure.
