Product Description

 

Three-Way Catalytic Converter (TWC) is a key device used to reduce harmful emissions from automobile exhaust. It converts carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) into harmless carbon dioxide (CO2), water (H2O), and nitrogen (N2) through catalytic reactions.

 

Structure

 

 1. Shell:
Material: usually made of stainless steel, with good high temperature and corrosion resistance.
 2. Substrate: 
Materials: Common substrate materials include honeycomb ceramics (such as cordierite, silicon carbide) and metal materials (such as stainless steel). 
3.Catalyst Coating: 
Material: The catalyst is usually composed of precious metals (such as platinum Pt, palladium Pd, Rhodium Rh) that are precisely sprayed onto the support. 
4. Thermal Insulation Layer: 
Material: The thermal insulation layer is usually made of high temperature ceramic fiber or thermal insulation felt. 
5. Sealing Gasket: 
Material: Sealing gasket is usually made of high temperature and heat resistant material, such as graphite, ceramic fiber, etc. 
6. Support Structure: 
Material: Support structures are usually made of metal brackets or ceramic materials.

 

Installation Instructions

 

 

The installation position of the three-way catalytic converter for gasoline vehicles
 Core position: 
the three-way catalytic converter is usually installed in the front section of the exhaust system, that is, between the engine and the muffler, immediately after the oxygen sensor (front oxygen sensor). 
Typical model installation example: Volkswagen EA888 engine: The catalytic converter is located in the engine compartment, near the turbocharger outlet. BMW B58 straight-six engine: The catalyst is integrated behind the exhaust manifold. 
Specially designed 
Turbocharged models: 
The catalytic converter may be integrated between the turbocharger and the exhaust manifold (such as the Porsche Taycan). 
Hybrid models:
 In order to accommodate frequent start-stop, the catalytic converter needs to be close to the engine to heat up rapidly (such as the Toyota THS II system).

Diesel Particulate Filter (DPF) installation position 
1. Diesel vehicle installation position DPF is usually installed in the rear of the exhaust system, behind the turbocharger or under the chassis. 
 High temperature regeneration requirements: DPF needs to be periodically regenerated at high temperature (active or passive), away from the engine to avoid thermal shock, but need to retain sufficient temperature (above 250°C). 
Spatial layout: The DPF of heavy diesel vehicles (such as trucks) is often integrated in the chassis exhaust road, while light vehicles (such as passenger cars) may be arranged near the engine compartment. 
2. Integrated design Installation
 DPF+SCR integration: Some models combine DPF and SCR catalytic converters into one module (such as Ford EcoBlue diesel engine) to reduce pipeline length. 
Urea injection system linkage: A urea nozzle installation position should be reserved near the DPF for NOx reduction in the SCR system.
 3. Installation of hybrid models for special models: 
Diesel hybrid vehicles: (such as Audi SQ7 TDI) may integrate DPF in the exhaust path of electric mode and fuel mode switching, and temperature management under both conditions must be taken into account. 
New energy transition technology: 
plug-in hybrid diesel vehicles do not work in pure electric mode DPF, but still need to rely on the original installation position to complete regeneration when starting the engine

 

Our Advantages

 

The three way catalytic converter needs to be replaced for the following reasons:
1. Function failure leads to excessive emissions catalyst poisoning: The use of leaded gasoline, inferior fuel or oil additives containing sulfur/phosphorus and other components will lead to the loss of catalyst activity, unable to effectively transform CO, HC, NOx.
2. Carbon deposition and blockage: long-term uncleaned carbon deposition will cover the internal honeycomb structure of the catalytic converter, reducing the efficiency of exhaust gas passing, and the exhaust gas test may show that CO and HC exceed the standard (fault code P0420).
3. High temperature sintering or mechanical damage: engine overheating or external impact may lead to the catalytic converter ceramic carrier rupture, at this time need to be replaced directly.
4. Regulations and annual inspection require national emission standards (such as Euro VI) to force the three-way catalytic converter to function normally. If the exhaust gas test does not pass (such as CO emission exceeding the limit), the vehicle cannot pass the annual audit.
5. Cause associated failure engine performance decline: catalytic converter blockage will lead to poor exhaust, manifested as insufficient power, increased fuel consumption, and even trigger engine failure lights (such as false alarms from oxygen sensors).
6. Other components are affected: Long-term high back pressure may damage the turbocharger or exhaust system pipelines
