The converter unlimited or ‘Cat-Con’ is a mechanical device. It reduces the harmful emissions created in the exhaust system of an engine. It is an important device as it works with the harmful gases, which the engine creates during combustion of fuel. The main purpose of a converter unlimited is to reduce exhaust emissions.
The Cat-Con reduces the harmful exhaust gases through chemical reactions. It reacts with the harmful pollutants in the exhaust gases and turns them into lesser harmful gases. The converter unlimited consists of a special catalyst. It is made of platinum and palladium which carries out the chemical reactions.
Construction of converter unlimited:
The converter unlimited housing consists of a honeycomb core from inside. It is coated with precious metals such as platinum and rhodium. These metals react with the engine’s exhaust gases. They reduce the toxic contents of the gases and turn them into carbon dioxide and water.
At first, it reacts with the carbon monoxide generated by the combustion of gasoline. It also reacts with the hydrocarbons formed by unburned fuel and other nitrogen oxide emissions. Thus, the cat-con converts these gases into less harmful by-products which are the carbon-di-oxide, water vapor, and nitrous emissions.
Types of converter unlimited:
There are three different Types of Cat-Cons. The first type is the oxidation converter unlimited. It reduces harmful pollutants such as the carbon monoxide (CO) and fuel hydrocarbons (HC) in the exhaust. Simultaneously, it often uses a secondary air injection. However, the oxidation converter unlimited only reduces a portion of the pollutants.
Dual-bed:
The second type is the dual-bed converter unlimited which offers more perfection. It works in two stages. There are two elements which are situated one behind the other. The first stage helps in reducing the amount of nitrogen oxide emissions. The second stage reacts with the hydrocarbons created by unburned fuel and carbon mono oxide. The manufacturers also provide the secondary air injection in the two-stage type cat-con.
Three-Way converter unlimited:
The last type is the Three Way converter unlimited. The Three-way converter unlimited helps in converting the harmful gases exhausted from the engine into harmless gases. The engine exhaust gases contain hazardous substances that cause damage to the environment. These include the oxides of nitrogen, hydrocarbons and carbon monoxide. The three-way converter unlimited them into less harmful carbon-di-oxide, water, and nitrogen.
The three-way cat-con is the only device which reduces all the three pollutants in one go. It functions most economically. Thus, most manufacturers employ a three-way type in their vehicles which need to meet stringent emission standards.
Working of the Three-Way converter unlimited:
Furthermore, the three-way uses two converter unlimited; namely reduction converter unlimited and an oxidation catalyst. The oxidation converter unlimited is made of palladium and platinum whereas reduction catalyst is of rhodium and platinum. However, both of them come with a ceramic honeycomb structure. Besides, it is placed in a muffler like a compact unit which fits onto the exhaust pipe. Mainly, the automotive industry uses the Three-way Cat-con. This is because the vehicles have to pass many regulations for emission control.
Thus, the converter unlimited plays an important role in reducing the amount of pollution created. It also reduces the harmful emissions and gases created in the engine and the exhaust systems of all the cars across the globe.
