A Complete Guide on Catalytic Converters

 



What Is the Purpose of catalytic converters?

Catalytic converters employ a chamber known as a catalyst to transform dangerous substances from engine exhaust into harmless gases such as steam. They work by breaking up the hazardous molecules in the gases produced by a car before they released into the atmosphere.

The catalytic converter implies a large metal box positioned on the underside of a car. It consists of two pipes coming out of it. During the process of rendering the gases safe for expulsion, the convertor makes use of these two pipelines and the catalyst.

Gases introduced through an “input” pipe connected to an engine. These blasted over the catalyst, causing a chemical reaction that breaks the contaminants apart. The less-harmful gases are now routed into the second pipe, or “output,” which attached to an automobile’s exhaust.

What are catalytic converters Made Of?

So, what exactly are catalytic converters? A catalytic converter’s catalyst is often constructed of platinum or a comparable metal, such as rhodium or palladium. Gases pass through a ceramic honeycomb structure inside the cat housing. This is lined with metals that have specialized jobs that contribute to reducing emissions. Catalysts come in two varieties that may be found in a car:

Catalysts for nitrogen oxide reduction: These aid in reducing nitrogen oxide pollution by extracting oxygen. Nitrogen oxides tend to break down into nitrogen and oxygen gases, which are both safe on their own.

Oxidation catalysts: These convert carbon monoxide into carbon dioxide by adding oxygen in the opposite direction.

The oxygen (O2) sensor, also situated near the catalytic converter, tells a car’s electronic control unit (ECU) the quantity of oxygen is present in the exhaust fumes. This allows a vehicle to run on a more efficient air/fuel ratio, allowing the engine to supply enough oxygen to the converter to complete the oxidation process.

Catalytic Converter Types

As previously stated, there are two fundamental catalysts – reduction and oxidation – that can utilized to manage certain gases inside an exhaust system.

Depending on the vehicle’s year and the type of catalytic converter, a reduction catalyst may or may not be present. Catalytic converters classified into two types:

Two-way: These catalytic converters used on automobiles in the United States until 1981. They only have oxidation catalysts, which assist in converting carbon monoxide to carbon dioxide. Unburned and partially burnt hydrocarbons are converted to carbon dioxide and water.

Three-way: The three-way catalytic converters have been used since 1981. With the inclusion of a reduction catalyst, this operates the same as the two-way converter. As previously stated, this utilized to convert nitrogen oxides to nitrogen and oxygen gases.

Two-way catalysts are used in diesel engines, and the converters are also specifically built to function with diesel exhausts. These engines’ converters attempt to target particles known as soluble organic components. These are formed from hydrocarbons that have been linked to soot.

How Can Catalytic Converter Theft Be Prevented?

Thieves frequently target catalytic converters because the component contains expensive precious metals. Catalytic converters thefts are more common on vehicles with higher ground clearance since the part is easier to obtain.

There are an array of things you may do to help avoid theft regardless of the type of vehicle you have:

  •       If a secure garage is not available, park in well-lit areas near building entrances.
  •       Welding the catalytic converter to the car structure can make removal more difficult.
  •       Consider purchasing an aftermarket item, such as a metal cage, to cover the converter.
  •       Install a car alarm that includes a vibration alert sensor.
  •       Engrave your vehicle identification number (VIN) on the converter to make selling the item more challenging and warn you if your converter is stolen.

Symptoms of Catalytic Converter Failure

Fuel efficiency is deteriorating: When catalytic converters become blocked, the amount of airflow through your engine is reduced. As a result, your motor may begin to consume more fuel than usual, resulting in a visible decrease in fuel economy.

Examine the warning light: A check engine light can signal various problems. However, on cars made after 1996, there is a diagnostic system that will test the catalytic converter. If your converter fails, the air-to-fuel ratio sensors may cause the warning light to illuminate.

Smells like rotten eggs: catalytic converters may have internal damage, making it challenging to convert exhaust gases. As a result, there may be a sulfuric “rotten egg” odor.

CONCLUSION

Be The Part Of Eco-Friendly Catalyst Converter Recycling

Vehicles emit harmful compounds that contribute to pollution. But the amount of emission can be reduced with the catalytic converter . In the exhaust system of vehicles, the catalytic converter is fixed that is filled with chemical catalysts platinum and palladium mixture. This system prevents the formation of harmful gases in the vehicle. Extraction of the precious metal from the earth is hard because mining has a negative impact on the earth like platinum ore required tons of extensive energy for its digging process from the tunnels. There is need of, one ton of ore, to produce one ounce of platinum. After it's digging process, to get platinum out ore is treated with the chemicals. And the whole process that is required for its refining process forms the raw form causes extreme pollution. Platinum mines are dangerous to work, but the catalytic converter recycling can help to limit the requirement of platinum and other metals, this pollution to the environment can be limite

Are you a person who is fond of automobiles? Or, a person who loves to experiment with cars? Or, a person who wants to get benefits from their old junk car parts? If yes, then you must be aware of the term catalytic converter. They act like one most essential part of your cars and thus work as a pollution control device. Undoubtedly, catalytic converter proves itself as of great use and moreover, it promises the best benefits if a person is opting to  sell catalytic converters . Still confused, what catalytic converters exactly are and how it can provide amazing benefits to you? If yes, then well, Catalytic converters are pollution control devices enriched with different chemicals and thus worked with the combined group of platinum metals (PGM) platinum (Pt), rhodium (Rh) and palladium (Pd). The Platinum group of metals works for the conversion reactions that help in converting pollutants into the harmless gases, making it efficient for future usage.  While, on the o

A brief note on Catalytic Converter - QLD Catalytic Converters

Image
The catalytic converter is an automobile exhaust-system component which contains a catalyst than creates conversion of gases like combusted hydrocarbons and carbon monoxide into products like carbon dioxide and water. It is generally attached to a car’s exhaust to control its pollution. Catalytic converters are also used on locomotives, trucks, mining equipment, buses and motorcycles. The catalytic converter was invented in France. At the end of the 19th century, the catalytic converter was patented by Eugene Houdry, a French mechanical engineer. Inside the catalytic converter, the gases are flowing through a honeymoon like structure coated with the catalysts. Three different chemical reactions are happening at the same time. At first, it reacts with the carbon monoxide. With its finest structure, the  catalytic converter disposal  promises the best use for the car and the environment. The catalytic converter is not only a great source for your car but can also promise y
