Made in China catalytic converter for Volkswagen Sagitar

Product introduction

Premium catalytic converter for The Volkswagen Sagitar ，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. Efficient environmental purification capacity

Sagitta's three-way catalytic converter uses platinum (Pt), rhodium (Rh), palladium (Pd) and other precious metals as catalytic coatings, and converts harmful gases (CO, HC, NOx) in the tail gas into harmless carbon dioxide, water and nitrogen through REDOX reaction, significantly reducing pollutant emissions. Its operating temperature is about 350℃, and the catalytic efficiency is higher in the high temperature environment, and it meets the strict National sixth emission standard 128.

2. Optimized structure and layout

Dual catalytic converter design: Some Sagitta models (such as 2013 models, 2017 models) set two three-way catalytic converters in the exhaust system, respectively located in the exhaust manifold (head section) and the middle part of the exhaust pipe, forming a multi-level purification, to further improve the exhaust gas treatment effect 5.

Fixed installation: The catalytic converter is integrated in the first section of the drum near the exhaust manifold, and the shape is similar to the "marching kettle", which is convenient for the exhaust gas to quickly enter the catalytic reaction zone and shorten the purification path 210.

3. High temperature and heat insulation design

The three-way catalytic converter uses a double-layer stainless steel structure with a sandwich filled with insulation materials (such as asbestos) to effectively reduce heat loss and isolate the impact of high temperatures on other components of the engine compartment. This design not only improves the catalytic efficiency, but also extends the service life.

4. Maintenance convenience

No cleaning characteristics: Due to the high temperature working environment is sensitive to liquid water, the three-way catalytic converter usually does not need to be cleaned, and can be replaced directly if oxidation or blockage occurs, reducing the maintenance complexity 210.

Easy fault detection: By observing the exhaust manifold burning red, exhaust odor, oxygen sensor voltage difference before and after the performance, the owner can quickly determine whether the catalytic converter failure 210.

5. Adaptation and technology iteration

For different years and engine models, Sagitar's three-way catalytic converters have been adapted in mesh number (mesh density) and size. For example, the original catalytic converter uses 600-900 mesh filter element to balance the exhaust resistance and purification efficiency; The modified model (such as the competitive model) can be reduced to 200-300 mesh, improving the high speed performance while taking into account the environmental protection 511.

Sum up

Through material science, structure optimization and multistage purification design, Sagitar three-way catalytic converter achieves the balance of efficient emission reduction and stable performance. Its highlights are not only reflected in environmental compliance, but also take into account the convenience and long life characteristics of daily use, and is one of the core components of the vehicle emission system.
