OEM Catalytic Converter

With the OEM-grade cat using premium Heavy Metals to meet original  emissions targets. Each piece is made with SS304/SS409l mandrel-bent piping, and ceramic monolith substrates offer the best in durability, design, and longevity while meeting the highest emissions standards laser-cut flanges,  and OE-style connections. Most systems include new gaskets or clamps. This is an aftermarket piece priced significantly lower than the Genuine OEM  equivalent. Although Genuine OEM will be a higher quality overall it comes with a price tag typically 3-5x higher.So  DJN after-market catalytic converter is always a better choice for customers

Three-way catalyst substrate used in gasoline engine tail gas purifying system。The ceramic substrate is made of cordierite  and used for car catalytic converters. We can supply both ceramic elements coated with noble metals of Pt and Pd. Rh and ceramic elements without noble metals.

Advantages of TWC substrates

1.High specific surface area. ensure exhaust gas could contact weigh catalyst enough.

2. Stable water absorption. guarantee catalyst could be firmly and evenly coated on the surface of the substrate, so it's no waste for too thick coating

3. Fast in temperature rising. After starting up the engine, the temperature of the substrate could reach the active temperature of the catalyst in the shortest time.

4. Low exhaust resistance: ask exhaust resistance of the substrate to the engine low, so that it won't affect the performance of the engine.

5. High intensity: substrates work in bumpy cars, so the power of substrates must be too high to be destroyed.

6. Perfect assembly: substrates are parts of exhaust; perfect appearance and exact dimension could ensure assembly is perfect.

Universal catalytic converter

When the high-temperature automobile exhaust passes through the purification device, the catalyst in the three-way catalytic converter will enhance the activity of the three gases of carbon monoxide, hydrocarbons and nitrogen oxides, and promote certain oxidation-reduction chemical reactions on the surface of the catalyst. : Carbon monoxide is oxidized to colorless and non-toxic carbon dioxide at high temperature, hydrocarbons are oxidized to water and carbon dioxide at high temperature, and nitrogen oxides are reduced to nitrogen and oxygen. In this way, the three harmful gases have all become non-toxic and harmless common gases, and the automobile exhaust can be purified in this way.

Direct -fit catalytic converter

With strong economic strength, R & D ternary catalyst based on the technology both inside and outside the essence of a catalyst, using our country's rare earth resources, precious metals and non-precious metals and other raw materials mainly, and other chemical raw materials as a supplement, we have unique formula of high-tech, science, mature and complete production process with advanced automatic control thermal dedicated tunnel kiln production equipment to match the way the production of a series of three-way catalytic products to ensure that emissions from vehicles to meet the European II , Route, on the 4th standard.

DPF Diesel Particulate Filter for Catalytic Converter

With increasing appearance of diesel engine automobile, the particulate from emission, mainly carbon, enhances the pollution to the environment.Regulation for diesel engine, stipulating the particulate in diesel passenger cars emission should meet the criterion: below 2.0g/mile. The diesel particulate filter is able to filter above 80% carbon smoke particulate .For practical application, it would be a great help to solve the problem of air pollution.

TWC substrates

1Ceramic Honeycomb catalytic converter is a kind of effective molten metal filter. It's three-dimensional connected mesh structure and high porosity has many advantages,for example, large surface area of slags collection,large inner surface area of filtering,small flow resistance,good filtering effect,etc.

The preferred catalyst support structure is a honeycomb configuration which includes a variety of unobstructed parallel channels sized to through gas flow and bounded by thin ceramic walls. The walls of these channels provide the surface for precious-metal catalysts that convert noxious emissions into carbon dioxide, nitrogen and water vapor. We can provide honeycomb ceramic substrate has been coated and non-coated precious-metal.

Our Ceramic Honeycomb is made of cordierite, The cells density can be 100 cpsi, 300 cpsi , 400 cpsi or 600 cpsi. The usual cpsi (Cell Per Square Inch) for catalytic converter substrate is 400, the shape of ceramic converter substrate is round, racetrack,ellipse and other special shape according to the customers requirement.
