katalyyttitukina

Katalyyttitukina, also known as catalytic converters, are essential components in the exhaust systems of internal combustion engines. Their primary function is to reduce the toxicity of emissions produced by the engine, thereby improving air quality and complying with environmental regulations. Catalytic converters operate through a chemical reaction facilitated by a catalyst, which is typically made of platinum, palladium, and rhodium. These metals are coated onto a ceramic honeycomb structure, providing a large surface area for the reaction to occur.

The process begins when the exhaust gases pass through the converter. The catalyst lowers the activation energy required for the conversion of harmful pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), and unburned hydrocarbons (HC) into less harmful substances. Carbon monoxide is converted into carbon dioxide (CO2), nitrogen oxides are reduced to nitrogen (N2) and oxygen (O2), and hydrocarbons are oxidized into carbon dioxide and water (H2O).

Catalytic converters are crucial for reducing the environmental impact of vehicles. They are widely used in automobiles, trucks, and other internal combustion engine-powered vehicles. Regular maintenance and periodic replacement of the catalyst are necessary to ensure its effectiveness, as the catalyst can degrade over time due to exposure to high temperatures and the accumulation of soot and other contaminants.
