Product introduction
Car Parts Exhaus Catalytic Converters Fit Buick Malibu 1.5T，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. Core principles
Catalytic conversion: Platinum (Pt), palladium (Pd), rhodium (Rh) and other precious metals are used as catalysts to trigger oxidation and reduction reactions at high temperatures (400-800°C) :
Oxidation reaction: Conversion of CO and HC to carbon dioxide (CO₂) and water (H₂O).
Reduction reaction: decomposition of NOx into nitrogen (N₂) and oxygen (O₂).
2. Air-fuel ratio control: It is necessary to accurately maintain the theoretical air-fuel ratio (14.7:1), monitor and feed back to the ECU in real time through the oxygen sensor, and adjust the fuel injection amount to optimize the catalytic efficiency.
3. Fuel economy
Lower fuel consumption: After the exhaust is smooth, the engine efficiency is increased, which may lead to better fuel economy.
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.Installation procedure
Preparatory work
Vehicle cooling: Ensure that the vehicle is completely cooled to avoid burns.
Tools: wrench, oxygen sensor tool (if necessary), jack, safety support, gloves, goggles, etc.
New catalyst matching: Ensure that the new three-way catalyst model matches the vehicle (brand, displacement, emission standards).
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.
