Carbon monoxide (CO) → Carbon diox
Product introduction
Premium catalytic converter for The Volkswagen Golf 7 1.4T ，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 functions and design features
1. Exhaust gas purification and emission control
Conversion of harmful gases: Through platinum (Pt), rhodium (Rh), palladium (Pd) precious metal coating, CO (carbon monoxide), HC (hydrocarbons), NOx (nitrogen oxides) in the tail gas into harmless CO₂ (carbon dioxide), H₂O (water), N₂ (nitrogen), to meet the national Ⅴ/ national Ⅵ emission standards.
Adaptive turbocharging features:
1.4T engine exhaust gas temperature is high, flow fluctuation is large, catalytic converter adopts high-density ceramic carrier and high temperature resistant stainless steel shell, can withstand instantaneous high temperature above 800℃, avoid melting or cracking caused by turbine working conditions.
2. Optimize power and fuel efficiency
Reduce exhaust back pressure: Turbocharging relies on exhaust energy to drive the turbine, and blockage of the catalyst will increase the back pressure and weaken the turbine response. Smooth catalytic converters increase low speed torque and turbine insertion speed.
Precision control with oxygen sensor: there is an oxygen sensor before and after the catalytic converter, real-time monitoring of air-fuel ratio, feedback to the ECU to adjust fuel injection, to ensure maximum combustion efficiency, indirect reduction of fuel consumption.
Second, structural layout and technological innovation
1. Compact integrated design
Installation position: Located behind the turbocharger, directly connected to the front exhaust pipe, shorten the exhaust path and improve the turbine response speed.
Lightweight material: Thin-walled stainless steel shell is used to reduce weight and adapt to the lightweight body design of the Golf 7.
2. Double coating technology (some high-equipped models)
Upper coating: fast ignition, cold start (low temperature stage) can efficiently convert pollutants, reduce cold car emissions.
Lower coating: long-term stability to ensure continuous purification efficiency under high load conditions.
3. Collaboration with GPF (National Ⅵ model)
Some countries version VI Golf 7 1.4T is equipped with gasoline particle catcher (GPF), which is connected with the three-way catalytic converter to further capture PM (particulate matter), and attention should be paid to the collaborative maintenance of the two.
3. Common faults and performance
1. Cause of failure
Precious metal poisoning: long-term use of inferior fuel (sulfur, manganese content exceeds the standard) leads to a decline in catalyst activity.
Carbon blockage: Turbocharged engines are prone to carbon pollution carriers due to oil steam or direct injection.
Mechanical damage: The chassis scratches or high temperature causes the carrier to break.
2. Typical symptoms
Power attenuation: turbine hysteresis is obvious, and acceleration is weak (especially in the range of 2000~4000 RPM).
Increased fuel consumption: ECU increases fuel injection to compensate for increased exhaust resistance.
Fault alarm: The instrument panel lights up the engine failure light, and the diagnostic instrument shows P0420 (low catalytic converter efficiency) or P0130/P0153 (abnormal oxygen sensor).
Exhaust odor: cold start of the exhaust pungent (not fully converted HC/CO), serious accompanied by black smoke.
Iv. Maintenance and replacement suggestions
1. Daily maintenance
Use high-quality fuel: strictly add No. 95 and above unleaded gasoline to avoid sulfide poisoning catalysts.
Replace the spark plug/ignition coil regularly: prevent a fire from causing unburned mixture to enter the catalyst.
Avoid short-distance cold driving: try to let the engine reach the working temperature (90 ° C) to ensure that the catalytic converter is fully activated.
2. Rectify the fault
Infrared temperature measurement method: in the hot car state, the infrared thermometer is used to detect the temperature difference between the entrance and the exit of the catalyst, and the normal temperature difference should be ≥50℃ (the exit temperature is higher).
OBD diagnosis: Read the oxygen sensor data stream, if the front and back oxygen sensor signals tend to be consistent, indicating that the catalytic converter failure.
3. Change the precautions
Adaptation model selection:
Brand replacement parts (such as Bosch, NGK) : cost-effective (about 1500~3000 yuan), need to confirm support for 1.4T engine.
It is strictly prohibited to "straight-through" modification: removing the catalytic converter or using a hollow tube instead will lead to power drop, fault code reporting, and annual inspection is illegal.
V. Comparison with competitive products (Golf 7 1.4T vs. similar models)
Features Golf 7 1.4T competitor (e.g. Ford Focus 1.5T)
The catalyst layout is close to the turbine, shortening the exhaust path is usually located downstream of the turbine, and the path is longer
Temperature resistance 800℃+, suitable for high pressurization conditions of about 750℃, focusing on cost control
The maintenance cost of the original parts is higher, and the adaptability of the auxiliary parts is slightly poor
