Factory supply catalytic converters for Great Wall Wind Jun 5

Product introduction

Factory supply catalytic converters for Great Wall Wind Jun 5，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 role

High efficiency exhaust gas purification

Through the REDOX reaction, the CO (carbon monoxide), HC (hydrocarbons) and NOx (nitrogen oxides) emitted by the engine are converted into harmless CO₂ (carbon dioxide), H₂O (water) and N₂ (nitrogen), and the conversion efficiency can reach more than 90%. Its core structure is a honeycomb ceramic carrier, and the surface is sprayed with platinum (Pt), palladium (Pd), rhodium (Rh) and other precious metal catalysts, which accelerates chemical reaction under high temperature environment and significantly reduces pollutant emission.

Optimize power and fuel economy

Reduce exhaust resistance: A working three-way catalytic converter can keep the exhaust system unimpeded and avoid power drop due to blockage. If the catalytic converter is blocked, the exhaust resistance increases, which may lead to a 10%-15% increase in fuel consumption.

Auxiliary ECU control: The front and rear oxygen sensors monitor the oxygen content of the tail gas and feed back data to the ECU to adjust the air-fuel ratio, indirectly optimize the combustion efficiency and improve the power response.

Meet environmental regulations

The installation of a three-way catalytic converter is a necessary condition to meet the national 6B emission standards. If the catalytic converter fails or is stolen, exhaust emissions will exceed the standard, resulting in failure to pass the annual inspection, and even face fines.

2. Practical use and functional extension

Protect the engine and exhaust system

NOx in untreated exhaust gas is corrosive, and long-term exposure may damage exhaust pipes and engine components. The three-way catalytic converter extends the life of related components by converting harmful gases.

The shell is made of high temperature resistant metal material, and the internal honeycomb ceramic carrier is fixed by shock absorbing layer, which has strong vibration resistance and high temperature performance.

Reduce noise and provide back pressure

The three-way catalytic converters form resistance points in the exhaust system, which can reduce the exhaust resonance noise transmitted to the cockpit, and at the same time balance the low and medium speed torque through a reasonable back pressure design to improve driving comfort.

Anti-theft demand

Because of the precious metal coating, three-way catalytic converters are easy targets for theft. It is recommended to install a protective cover or park in a monitored area to reduce the risk of theft.

3. Maintenance and troubleshooting

Regular cleaning and maintenance

Cleaning cycle: It is recommended to clean every 10,000 kilometers or before the annual inspection, which can be used for bottle-free cleaning or oxalic acid soaking method (need to be disassembled).

Oil selection: The use of low-grade gasoline or inferior fuel is easy to lead to carbon accumulation, it is recommended to choose high-quality fuel from regular gas stations.

Fault symptoms and handling

Common faults: blockage, precious metal coating failure or carrier fragmentation, manifested as power drop, abnormal fuel consumption, harsh odor or abnormal noise of exhaust gas.

Fault light Alert: If the engine fault light is on the instrument panel, check the oxygen sensor data or catalyst status.

Replacement suggestion

The original catalytic converter has better adaptability, and the service life can reach 8-100,000 kilometers, but the cost is higher (about 2000-5000 yuan); Secondary factory parts need to choose quality certified products to avoid excessive emissions due to insufficient catalytic efficiency
