Product Description
High Performance Universal Wholesale Catalytic Converter for Exhaust System
Three-Way Catalytic Converter The three-way catalyst (TWC) is made of cordierite honeycomb ceramics as a carrier, rare earth composite oxides as additives, and a small number of precious metals (PD/PD/RH) added and sintered after a special coating process.
The product makes full use of the coordinated effects of precious metals and rare earth composite oxides. The carbon monoxide CO,hydrocarbons HC, and nitrogen oxides NOX in the exhaust gas undergo oxidation/reduction, thereby converting them into non-toxic carbon dioxide, water and nitrogen.

According to the different standards of the carrier required by the vehicle, the quality of the carrier is also different.
It can be divided into
It can be divided into
Euro 1 (white carrier, which does not have any exhaust filtering function, but only serves as a noise
reduction effect),
Euro 2 (addition of rare earth compound)
Euro 3 OBD (addition of platinum, palladium)
Euro 4 (addition of platinum, palladium, rhodium)
Euro 5 and other standards.

Ceramic honeycomb substrate (catalyst monolith) is a new kind of industrial ceramic product, as a catalyst carrier which are widely used in automobile emissions purifying system and industrial exhaust gas treatment system.
Catalytic converter substrate for vehicle:its major material is composed of cordierite and stainless steel of iron The material for catalytic converter substrate is cordierite. The natural cordierite exists very rare in nature, so most of cordierites are man-made substances. The major features for such cordierite are low thermal expansion coefficient, good thermal shock resistance, high anti-acid, anti-alkali and antii-erosion function and good mechanical strength.
The usual CPSI for catalytic converter substrate is 400. The shape of honeycomb ceramic is round, racetrack, ellipse and other special shape according to the customer's requirement in order to meet the different cars models requirements.Benefits of Products:
1)Low thermal expansion coefficient
2)High porosity of hole on the wall , good liquidity and uniform distribution.
3)High temperature resistance, chemical corrosion resistance, thermal shock resistance and thermal shock resistance is strong.
4)The pressure drop is small.
5)Cold start performance is good, low light-off temperature, high conversion efficiency.
