Catalytic Converter; An internal combustion engine’s exhaust gas contains poisonous gases and other pollutants that a catalytic converter transforms into less-toxic pollutants by accelerating a redox reaction. Typically employed with internal combustion engines powered by gasoline or diesel, including lean-burn engines, catalytic converters are also occasionally utilized with kerosene heaters and stoves. Should we find some critical underlying issue, Central Auto Repair Service offer you efficient catalytic converters using genuine OEF-grade spares at Central Works, Bridge Road, Worthing, BN14 7BU.

.The American motor industry saw the first wide-scale introduction of catalytic converters. Most gasoline-powered automobiles starting with the 1975 model year are outfitted with catalytic converters to meet with the U.S. Environmental Protection Agency’s tougher regulation of exhaust emissions. [1][2][3] These “two-way” converters create carbon dioxide (CO2) and water by combining oxygen with carbon monoxide (CO) and unburned hydrocarbons (HC) (H2O).

. Two-way catalytic converters are still used for lean-burn engines even though “three-way” converters that additionally reduce nitrogen oxides (NOx) made them obsolete in 1981[4]. This is since to effectively reduce NOx, three-way converters need either fuel-rich or stoichiometric combustion.

Despite being most frequently used in car exhaust systems, catalytic converters are also employed in electrical generators, forklifts, mining machinery, trucks, buses, locomotives, motorbikes, and ships. Even some wood stoves utilize them to regulate emissions. [5] Usually, this happens in response to governmental control, such as environmental rules or laws governing health and safety.

Catalytic converters’ Pollution Reduction Method

A catalyst in chemistry is a material that starts or speeds up a chemical reaction without changing itself. lf you are looking for catalytic converter repair services, we recommend you visit Central Auto Repair Service located at Central Works, Bridge Road, Worthing, BN14 7BU.

. Despite being a part of the reactions, catalysts are neither reactants nor products of the ones they catalyze. Enzymes are naturally occurring catalysts that carry out numerous vital biochemical activities in the human body.

A reduction catalyst and an oxidation catalyst are the two different types of catalysts at work in the catalytic converter. Both forms use a metal catalyst, typically platinum, rhodium, or palladium, that is coated on a ceramic framework. Central Auto Repair Service with your consent, if the damages are too severe.


A close-coupled catalytic converter is a common car component that is placed close to the exhaust manifold. Due to its exposure to the extremely hot exhaust gases, the converter heats up fast, allowing it to reduce harmful emissions while the engine is warming up. This is accomplished by burning off extra hydrocarbons produced by the necessary extra-rich mixture.

The majority of automobiles used carburetors, which offered a rather high air-to-fuel ratio when catalytic converters were first introduced. As a result, the exhaust stream typically lacked enough oxygen (O2) for the catalytic reaction to work effectively. Therefore, secondary air injection, which injected air into the exhaust stream, was a feature of the majority of designs at the time. As a result, there was more oxygen accessible, which helped the catalyst work as it should.

Some three-way catalytic converter systems have air injection systems that inject air in between the first stage of the converter (NOx reduction) and the second stage (HC and CO oxidation). This injected air provides oxygen for the oxidation reactions, just like in two-way converters.

Unburned fuel is ignited in the exhaust system as a result, preventing it from ever reaching the catalytic converter. By using this method, the amount of engine runtime required to get the catalytic converter to the “light-off” or operating temperature is decreased.
