Automotive Urea Liquid
Diesel Exhaust Treatment Fluid
Diesel exhaust treatment fluid, as an important part of modern diesel vehicle environmental protection technology, its importance is self-evident.
following is a detailed introduction to diesel exhaust treatment fluid, covering its definition, composition, role, use, storage and precautions and other aspects.
1. Definition and Overview
Diesel exhaust treatment fluid, often called automotive urea, is a special liquid used to reduce nitrogen oxides (NOx) emissions in the exhaust of diesel vehicles.
It significantly reduces environmental pollution from diesel vehicle exhaust by chemically reacting with the NOx in the exhaust and converting it into harmless nitrogen and water vapour.
Automotive urea is a colourless, transparent and clear liquid, which is made of high-purity urea and ultra-pure water (or deionised water) mixed in a certain proportion.
2. the Composition
The main components of the diesel exhaust treatment fluid are 32.5% high-purity urea and 67.5% ultra-pure water (or deionised water).
This specific concentration ratio is verified through scientific research and experiments to ensure that the urea aqueous solution in the SCR (selective catalytic reduction) system to play the best reduction efficiency.
At the same time, the aqueous urea solution at this concentration also has a low freezing point (-11℃), which can maintain its stable performance in a low-temperature environment.
3. the Role and Function
Reducing NOx emissions:
Diesel exhaust treatment fluid is the core consumable of SCR technology, which significantly reduces NOx content in diesel vehicle exhaust by chemically reacting with the NOx in the exhaust and converting it into harmless nitrogen and water vapour.
This is important for improving air quality and reducing environmental pollution.
Protecting the environment:
With the increasingly stringent environmental regulations, diesel exhaust treatment fluid has become a necessary product for diesel vehicles to meet emission standards.
Through the use of qualified exhaust treatment fluid, diesel vehicles can significantly reduce the content of harmful substances in their exhaust, contributing to the protection of the environment.
Improve vehicle performance:
Long-term use of qualified exhaust gas treatment fluid can keep the exhaust gas treatment system functioning properly, avoiding system clogging and malfunctioning.
This helps to improve the overall performance and reliability of the vehicle and prolong its service life.
4. the Use of Methods
Adding method:
Diesel vehicle exhaust gas treatment fluid needs to be added to the vehicle’s urea tank on a regular basis.
In the process of adding, should ensure the use of special filling tools and clean filling port, to avoid impurities mixed in.
At the same time, it is also necessary to pay attention to the control of the filling amount to avoid over or under.
Precautions for use:
Do not stop using the vehicle until the tailpipe treatment fluid is completely consumed, otherwise the tailpipe treatment system will fail.
Regularly check the consumption of exhaust gas treatment fluid and add it in time as needed.
Avoid using poor quality or substandard tailpipe treatment fluid, which may cause damage to the vehicle and tailpipe treatment system.
5. Storage and Precautions
Storage conditions:
Diesel vehicle exhaust treatment fluid should be stored in a cool, dry and well-ventilated place, avoiding direct sunlight and high temperature environment.
The storage temperature should be kept between -5℃~25℃, there should be heat preservation measures when it is lower than -5℃, and it should be cooled down when it is higher than 25℃.
If the exhaust gas treatment fluid crystallises, the heating temperature should not be higher than 30℃.
Prevent pollution:
diesel exhaust treatment fluid is weakly alkaline and very sensitive to potential chemical impurities.
To prevent contamination, keep the storage environment clean and avoid contact with foreign objects. Care should also be taken to avoid man-made contamination during refuelling and handling.
Safety Note:
Although the toxicity of Diesel Exhaust Treatment Fluid itself is low, attention should still be paid to safety precautions during use and storage.
Avoid direct contact with skin and eyes. If contacted inadvertently, immediately flush with plenty of water and seek medical attention.
