Product introduction
Premium catalytic converter for Volkswagen Bora 1.6，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. Basic definition and core functions
Essence:
The ternary catalyst (TWC) is a honeycomb ceramic/metal support device installed in the middle of Bora Classic exhaust pipe, coated with platinum (Pt), palladium (Pd), rhodium (Rh) and other precious metal catalysts.
Core functions:
Through the REDOX reaction, the CO (carbon monoxide), HC (hydrocarbons) and NOx (nitrogen oxides) in the exhaust gas are converted into harmless CO₂ (carbon dioxide), H₂O (water vapor) and N₂ (nitrogen), and the conversion efficiency can reach 85%-90% (new car state).
2, the special design of Bora classic three-way catalytic converter
Material and structure
Carrier type:
Early models mostly used 400-mesh cordierite ceramic honeycomb carrier (later upgraded to 900 mesh), taking into account purification efficiency and exhaust resistance.
Coating technology:
Cerium (Ce) based oxygen reservoir was added to domestic low grade gasoline (containing lead) in the 2000s to alleviate the effect of lead/sulfur poisoning on the activity of precious metals.
Engine suitability
Naturally aspirated engines (such as 1.6L BTS engines) : Catalytic converter volume of about 1.2L, matching low-flow exhaust characteristics.
Turbocharged engines (e.g. 1.8T BKB engines) : with a tightly coupled design (close to the exhaust manifold), rapid heating up to the operating temperature (above 300 ° C).
Oxygen sensor linkage
In conjunction with the front oxygen sensor (λ sensor), real-time air-fuel ratio data is fed back to the ECU to optimize the fuel injection amount (older models are mostly single-oxygen sensor systems).
3. Common faults and impacts
Lead/sulfur poisoning (high incidence of older vehicles)
Cause: Long-term use of leaded gasoline or high-sulfur fuel, the surface of the precious metal is covered, lose catalytic activity.
Symptoms: harsh exhaust gas (HC not converted), 10%-15% increase in fuel consumption, engine fault light (fault code P0420).
The ceramic support is broken
Cause: severe turbulence or exhaust pipe bottom impact, resulting in carrier rupture plugging exhaust.
Performance: weak acceleration, abnormal exhaust sound (similar to metal friction sound), maximum speed limited.
Carbon plugging
Reasons: long-term short distance driving, catalyst temperature is insufficient, unburned hydrocarbons condensation adhesion.
Consequences: Exhaust back pressure increases, turbo response is delayed in turbocharged models (1.8T), and low-speed torque drops by 20%-30%.
4, maintenance and replacement of key points
Fuel selection
Unleaded gasoline (National IV and above standard) must be used to avoid permanent damage caused by lead deposition.
If it is parked for a long time, it is recommended to drive for more than 30 minutes every 3 months to maintain the working temperature of the catalytic converter.
Cleaning and regeneration
Physical cleaning: After removing the catalyst, soak oxalic acid solution (concentration 5%-8%) for 2 hours to dissolve the sulfide caking.
Chemical regeneration: Use a special catalytic cleaner (such as BG Platinum) to remove the surface passivation layer through the fuel system.
Replacement decision
Replacement threshold: CO > 1.2% in exhaust gas, HC > 200ppm, or carrier physical damage.
Accessories selection:
Original parts: Number such as 06A 254 001C (for 1.6L models), the price is about 2000-3000 yuan.
Alternate factory: Recommend BOSCH, Walker and other brands, make sure that the interface matches the original car exhaust pipe diameter (such as φ50mm).
Installation precautions
After replacement, the diagnostic instrument should be used to reset the ECU fuel correction value to avoid the imbalance of air-fuel ratio.
Check that there is no air leakage from the exhaust manifold to the catalyst section, or the oxygen sensor signal is out of alignment.
5. Environmental protection upgrade plan for classic models
Country three liters country four: Replace the highly active three-way catalytic converter (precious metal content increased by 20%), with the upgrade of the oxygen sensor (such as replacing the four-wire broadband sensor), can make the exhaust gas meet the national four standard.
OBD compatibility: The old Bora classic has no OBD-II interface, which requires an external exhaust gas analyzer for manual detection.
