What is automotive grade urea?

Automotive grade urea, also known as diesel exhaust fluid (DEF), is a high-purity solution of urea in deionized water. It is used as a consumable in diesel engines with selective catalytic reduction (SCR) systems to reduce nitrogen oxide (NOx) emissions.

In the SCR process, the diesel exhaust fluid is injected into the exhaust gas stream where it reacts with the NOx emissions to convert them into harmless nitrogen and water vapor. Automotive grade urea is specifically formulated for use in SCR systems and meets stringent purity and quality standards to ensure reliable and efficient operation of the SCR system.

The purity of automotive grade urea is critical to prevent contamination of the SCR system, which could result in costly repairs or even failure of the system. It is typically available at fueling stations and automotive supply stores in containers ranging from small bottles to large bulk tanks.

How to use Automotive grade urea?

Automotive grade urea is used in diesel engines equipped with selective catalytic reduction (SCR) systems. Here are the steps to use it properly:

1. Locate the DEF tank: The DEF tank is usually located near the fuel tank and is labeled with the blue DEF cap.

2. Check the DEF level: Check the DEF level using the gauge or indicator on the dashboard or by manually checking the level in the tank.
   

3. Purchase the correct DEF: Make sure to purchase automotive grade urea that meets the specifications of your vehicle's SCR system.
   

4. Open the DEF cap: Open the blue DEF cap on the tank and insert the DEF nozzle.
   

5. Fill the DEF tank: Slowly fill the DEF tank until it reaches the recommended level.
   

6. Close the DEF cap: Close the DEF cap securely to prevent contamination or evaporation.
   

7. Check for leaks: After filling the DEF tank, check for any leaks or spills and clean them up immediately.
   

It is important to follow the manufacturer's guidelines for using automotive grade urea and to use only approved DEF products to ensure proper operation of the SCR system and minimize the risk of damage to the engine.

Store Automotive grade urea

Should be stored properly to maintain its purity and quality. Here are some guidelines for storing automotive grade urea.

1. Store in a cool, dry place: Automotive grade urea should be stored in a cool, dry place, away from direct sunlight and heat sources. The ideal temperature range for storage is between 12°C and 25°C (54°F to 77°F).

2. Keep the container sealed: The container should be kept tightly sealed to prevent contamination and evaporation.

3. Avoid exposure to air: Automotive grade urea can absorb moisture from the air, so it is best to keep it in an airtight container.

4. Do not mix with other fluids: Do not mix automotive grade urea with any other fluids, as this can contaminate the solution and cause damage to the SCR system.

5. Check the expiration date: Make sure to use DEF before the expiration date printed on the container.

6. Rotate stock: If storing large quantities of DEF, use the first-in, first-out (FIFO) method to ensure that the oldest stock is used first.

By following these guidelines, you can ensure that your automotive grade urea remains pure and effective when you need it to reduce NOx emissions in your diesel engine with SCR technology.

Automotive grade urea liquid transportation 

Automotive grade urea （Diesel Exhaust Fluid  DEF） is a solution of 32.5% high-purity urea and 67.5% deionized water that is used in diesel engines to reduce harmful nitrogen oxide emissions. Here are some guidelines on how to transport automotive grade urea:

Use a dedicated container: DEF should be transported in a dedicated container that is specifically designed for this purpose. This can be a bulk tanker truck, a tote, or a drum.

Protect from contamination: DEF is highly sensitive to contamination, and even small amounts of dirt or dust can render it ineffective. Ensure that the container is clean, and use dedicated pumps and hoses to prevent contamination.

Avoid exposure to high temperatures: DEF should be transported and stored at temperatures between 12°F and 86°F (-11°C to 30°C). Avoid exposing the container to direct sunlight or storing it near sources of heat.

Prevent freezing: DEF will freeze at temperatures below 12°F (-11°C). If the DEF freezes, it may cause damage to the container or the engine. Ensure that the container is properly insulated and use a heater if necessary.

Follow regulations: There may be regulations regarding the transportation of DEF in your area. Ensure that you comply with all relevant regulations, including the appropriate labeling of the container and documentation of the transport.

By following these guidelines, you can safely and effectively transport automotive grade urea, ensuring that it arrives at its destination in optimal condition.
