Product introduction
High Quality Catalytic Converter for Buick Lu Zun 2.4，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. How it works
Catalyst action: Internal coating platinum (Pt), palladium (Pd), rhodium (Rh) and other precious metals as catalysts to accelerate the chemical reaction.
Chemical reaction:
Oxidation reaction: CO and HC are oxidized to carbon dioxide (CO₂) and water (H₂O).
Reduction reaction: NOx is decomposed into nitrogen (N₂) and oxygen (O₂).
2. Working conditions
High temperature: need to reach about 250°C or more to work efficiently (cold start efficiency is lower).
Air-fuel ratio control: Rely on oxygen sensors to monitor the exhaust gas and ensure that the engine fuel mix ratio is close to the theoretical value (14.7:1) to maintain the optimal catalytic efficiency.
3. Applicable vehicle type
Gasoline vehicles: especially vehicles equipped with electric injection systems and closed-loop control.
Diesel vehicles: Due to different combustion characteristics, SCR (selective catalytic reduction) and other technologies are used to deal with NOx.
4. Precautions
Matching model: The catalytic converter that matches the original car must be selected, otherwise the performance may be affected or the fault code may be triggered.
Avoid inferior products: Inferior catalysts have low conversion efficiency, may not pass emission detection, and even block exhaust gas.
Check the root cause: If the old catalytic converter is damaged due to engine problems such as burning oil and ignition problems, the source needs to be repaired first, otherwise the new catalytic converter will be damaged again.
High cost: the original catalytic converter is expensive, and the auxiliary parts need to be carefully selected.
5. Failure performance
Emission deterioration: increased exhaust pollutants, annual inspection is not up to standard.
Performance decline: rising fuel consumption, insufficient power, poor exhaust and even abnormal sound.
Fault warning: Abnormal oxygen sensor triggers engine failure light.
6. When do I need to replace it?
Annual inspection discharge is not up to standard
Power decreased significantly and fuel consumption increased abnormally
Engine fault light is on and catalyst failure is detected
Abnormal exhaust sound or weak acceleration
You are advised to check the cause of the fault before replacement to avoid unnecessary costs.
7.Install the new catalytic converter
Check the gasket: Replace the gasket or ring with a new one to ensure air tightness.
Alignment Position: Align the new catalytic converter with the exhaust pipe interface and ensure that the installation direction is correct (the arrow usually points in the direction of the air flow).
Fastening bolts: Tighten the bolts gradually in diagonal order to avoid uneven force (refer to the maintenance manual for torque).
Install the oxygen sensor: Reinstall the oxygen sensor to the new catalyst, making sure the connection is secure.
