How Does The Catalyst In A Catalytic Converter Work

Exhaust has a lot to do with performance. The inside of a catalytic converter contains a metal or ceramic substrate or a surface on which chemical reactions occur.

Catalytic Converters Are Used To Convert The Harmful Componuds Of The Vehicle Into Carbon Dioxide They Are Mostly App Exhausted Converter Performance Mufflers

The reduction catalyst is the first stage of the catalyticconverter.

How does the catalyst in a catalytic converter work. The oxidation catalyst is the second stage of the catalytic converter. So how does the catalyst convert these elements. The catalyst support or substrateFor automotive catalytic converters the core is usually a ceramic monolith that has a honeycomb structure commonly square not hexagonal.

The nitrogen atoms bond with othernitrogen atoms that are also stuck to the catalyst formingN2. It uses platinum and rhodium to help reducethe NOx emissions. Selective Catalytic Reduction SCR The SCR catalyst is something that might cause a few converter buyers to raise an eyebrow.

This section of the diesel converter is typically the largest and yet it has very little recycle value. The converter doesnt have to work extremely hard to perform its tasks. The Three-way catalyst helps in converting the harmful gases exhausted from the engine into harmless gases.

These include the oxides of nitrogen hydrocarbons and carbon monoxide. This is the component that carries out the reduction of the NOx gases. You can think of your catalytic converter as a dating agency for exhaust pollutants helping them meet their ideal partner and converting them to carbon dioxide and water vapour.

Catbacks Mufflers and resonators get all the attention but the Catalytic Converter is super cool too. This catalyst aids the reaction of the CO and hydrocarbons with the. These catalysts comprise of a thin layer of platinum rhodium andor palladium.

Some of the chemical reactions that take place in the catalytic converter are shown below. The catalytic converters construction is as follows. The typical working temperature varies from 1200 to 1600 0 F.

Theyre tucked deep in the exhaust to work as efficiently as. The last type is the Three Way Catalytic Converter. The catalytic converter is part of the exhaust system processing all exhaust leaving the engine before it can escape into the atmosphere.

Catalysts break down the harmful exhaust gases coming from the engine by separating the atoms which make up these molecules. The engine exhaust gases contain hazardous substances that cause damage to the environment. How Does a Catalytic Converter Work.

How does a catalytic converter work. When an NO or NO2moleculecontacts the catalyst the catalyst rips the nitrogen atomout of the molecule and holds on to it freeing the oxygenin the form of O2. The basic diagram below shows in principle how a catalytic converter works.

So if you are planning to travel to a new city you should expect your car to release gaseous chemicals for some few minutes10 15 minutes before the catalytic converter will begin to work. A brief description of what goes on inside a catalytic converter. Prior to the mid 1980s the catalyst material was deposited on a packed bed of alumina pellets in early GM applications.

Conversely as the sum of toxin in the tailpipe increases the operating heat also increases. A catalytic converter is said to only be effective when it is warm high temperature of 300C800F or more is required warming a catalytic converter could take up to 10 -15 minutes of driving. It reduces the unburned hydrocarbons and carbon monoxide by burning oxidizing them over a platinum and palladium catalyst.

Catalytic converters contain catalysts chemicals which speed up the process of chemical reactions which themselves do not change during this process. Anywhere between 4-9 grams of these precious metals are used in a single catalytic converter. The standard light off temperature which catalytic converter starts to work ranges from 400 to 600 0 F.

A bad or clogged catalytic converter can ultimately lead to engine failure so its important to address the issue promptly. Catalytic converters are found in pretty much every car but you rarely ever see them.
