Three Way Catalytic Converter with Ceramic Honeycomb Substrate & Metallic Carrier Catalyst

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.

The conventional dimensions of the honeycomb ceramic catalyst carrier are: Dia80*80, Dia93*80mm, Dia93*100mm, Dia 100*100mm, Dia 101.6*100mm, Dia103*100mm, Dia 106*100mm, Dia 110*100mm, Dia 118*100mm, Dia 130*100mm.
 

Three-Way Catalytic Converter Uses advanced spiral wound ultra thin foil Our Three-Way Catalytic Converters are constructed of high temperature tolerant, corrosion resistant steel alloys. Thick steel alloy retainers are used to provide support and stability for the inlet and outlet faces of the metallic core. The effects of high thermal shock and severe vibration are minimized. The larger model catalytic converters (Models 12 SXT and higher) feature inlet flow diverters for even exhaust flow distribution and improved operating efficiency.	Three-Way Catalytic Converter Uses advanced welding process Our 3 way catalytic converters feature high strength, ultra-thin metallic core walls which impose a minimal exhaust gas restriction during operation. Even under high load/speed conditions the average engine operating efficiency is barely affected. Under normal circumstances the exhaust gas back pressure restriction will be in the order of 6.0" to 9.0" water gauge (depending on exhaust gas temperature).
Honeycomb Metallic substrate (catalyst) metallic catalyst substrates are made of thin metal foils, flat and corrugated, formed into a honeycomb structure which is placed inside a metal shell, the advantages of metal substrates are their high geometric surface area and low pressure drop associated with the thin walls. The foils in metallic substrates can be brazed/welded together to provide good mechanical durability and resistance to thermal shock. The major disadvantage of high quality metallic substrates is their high cost.	DPF (Diesel Particulate Filter) DPF (Diesel Particulate Filter) is an exhaust aftertreatment device that traps particulate matter such as soot and ash. A DPF typically uses a substrate made of a ceramic material that is formed into a honeycomb structure. A DPF has been a requirement of all new diesels since 2009 when the 'Euro 5' emissions standard came into force.

1. What is a Three-Way Catalytic (TWC) Converter?

TWC is a mechanism that is used in the automotive industry to filter harmful gases such as oxides of nitrogen and carbon dioxide. After the TWC processing, the harmful gases turn into harmless exhausts, and this is the whole point.

2. How Does it Work?

Three-Way Catalytic Converters (TWC) works like many other catalysts that process car exhaust gases. The operation of this device is based on a chemical reaction using a special structure and valuable materials that are inside. Incoming gases from the engine enter the exhaust system, where carbon oxides and other harmful emissions are processed into harmless ones such as water or nitrogen. The operation of this type of catalyst occurs at very high, almost extreme temperatures. Thus, it is better to keep an eye on it and not overheat the device in order to avoid possible troubles and breakdowns. 

3. How do automakers use this type of catalyst?

Car manufacturers are constantly improving their cars by creating and installing new types of catalysts inside new models. And the new three-way catalyst shows its best side compared to other catalysts, thereby proving itself in the auto industry in terms of environmental problem and overall quality. Many car companies have long since switched to new catalysts and are using them to the fullest because of the efficiency they show.
