Environmental concerns have not emerged recently, but in recent years the search for a sustainable production system has intensified. This concern also affects means of transport, especially trucks.
As it is the most widely used transport system in Brazil, the concern with reducing polluting agents produced by trucks and other large vehicles is a crucial aspect for the country's environmental preservation and one of the ways to mitigate these emissions is through the use of nitrogen oxide depleting agents, also known as Arla.
Next, we will learn more about what Arla is, its importance and which products are most suitable for its use.
What is Arla
The term “Arla” is an abbreviation for “Liquid Nitrogen Oxide Reducing Agent”. This is a liquid solution used in diesel vehicles previously equipped with selective reduction systems (or SCR) to reduce the emission of nitrogen oxides (NOx) produced by the combustion of fuel. Arla is a mixture of high-purity urea and demineralized water.
In the SCR system, Arla is injected into the engine exhaust, where a chemical reaction occurs with the hot exhaust gases. This reaction transforms nitrogen oxides into nitrogen and water, thus reducing air pollution. The addition of Arla is a measure that aims to comply with the most stringent pollutant emission reduction standards established in several regions of the world.
It is also important to note that Arla 32 is a common commercial name for this solution, as its urea content of 32.5% is one of the most common measurements found.
Importance
We can see that Arla plays a fundamental role in reducing pollutant emissions from vehicles equipped with SCR systems. Now let's delve a little deeper into this issue:
Reduction of nitrogen oxide (NOx) emissions
As previously stated, Arla is designed to react with exhaust gases in the SCR system and convert NOx into nitrogen and water. Nitrogen oxides are harmful air pollutants that contribute to air pollution and have detrimental effects on human health. The use of Arla helps to significantly reduce emissions of this component and, consequently, helps to improve air quality.
Compliance with emissions standards
In many countries, there are strict regulations regarding the emissions of certain chemical components from vehicles, especially for diesel vehicles. The use of Arla is a measure that helps to comply with these standards, ensuring that vehicles are within the permitted limits of pollutant emissions.
Environmental sustainability
By reducing NOx emissions, Arla contributes to protecting the environment. Air pollution can negatively affect the quality of soil, water and ecosystems, as well as causing damage to flora, fauna and biodiversity. By using Arla, we are helping to minimize these impacts and promote environmental sustainability.
Improved engine efficiency
One of the side effects of using Arla is that in addition to reducing emissions, using Arla in vehicles with SCR systems can result in an overall improvement in engine efficiency. This is because the reduction of nitrogen oxides allows for better performance and cleaner engine operation, which can result in more efficient fuel consumption.
Equipment
To fill a vehicle with Arla, the vehicle must have some equipment, let's find out a little more about them:
Arla Tank
The vehicle must be equipped with a specific tank to store Arla. This tank is usually located near the fuel tank.
Supply Nozzle
THE supply nozzle It is similar to a pistol and is designed to fit into the vehicle's Arla tank inlet. It usually has a safety lock to prevent leaks.
Hose
The filling pump is connected to the filling nozzle by means of a flexible hose. The hose enables the safe transfer of Arla from the filling equipment to the vehicle's tank.
Electrical supply kit for Arla 32
THE electrical supply kit It is made up of different components that facilitate the storage, measurement and precise injection of Arla 32. It generally includes a storage tank for the fluid, an electric pump for transferring the liquid, a measurement and control system to ensure adequate dosage, as well as sensors and electrical cables to connect the kit to the vehicle.
Electronic flow meter for Arla 32
THE electronic flow meter uses advanced electronic technology to monitor the flow of Arla 32 in real time. It is usually installed in the supply line, between the fluid storage tank and the injection system. The meter has sensors that detect the fluid flow and convert this information into electrical signals that are processed to determine the exact amount of Arla 32 being injected.
When filling your vehicle with Arla, it is important to follow the vehicle and filling equipment manufacturer's instructions. Be sure to use the correct filling nozzle and handle the equipment carefully to avoid spilling or contaminating the Arla.
