Diesel Exhaust Fluid (DEF) system cleaners are essential products that keep the DEF system clean and free from contaminants. These cleaners are used in diesel engines with a selective catalytic reduction (SCR) system to reduce NOx emissions. However, there are certain mistakes that users should avoid while using DEF system cleaners. This article will discuss these mistakes and how to avoid them.
Mistake 1: Using the Wrong DEF System Cleaner
Using the wrong DEF system cleaner can cause damage to the SCR system and reduce its efficiency. Therefore, using the manufacturer’s recommended DEF system cleaner is essential. The wrong cleaner may contain different chemicals, which may cause corrosion or damage to the system. Always check the cleaner’s label to ensure it is compatible with your engine.
Mistake 2: Using Too Much DEF System Cleaner
Using too much DEF system cleaner can cause harm to the engine and the SCR system. Overuse of the cleaner may result in the formation of deposits that can clog the system and cause damage. It is recommended to use the cleaner as directed by the manufacturer. Using too much cleaner can also be wasteful and may not improve the system’s performance.
Mistake 3: Not Using the DEF System Cleaner Regularly
Not using the DEF system cleaner regularly can lead to the build-up of contaminants in the SCR system. This build-up can lead to decreased system efficiency and an increase in emissions. Using the cleaner at least once a year or as recommended by the manufacturer is recommended. Regular use of the cleaner helps to maintain the system’s efficiency and extends its lifespan.
Mistake 4: Not Following the Correct Procedure for Using DEF System Cleaners
Not following the correct procedure for using DEF system cleaners can lead to ineffective cleaning and even damage to the system. The correct procedure involves adding the cleaner to the DEF tank and allowing it to circulate through the system. It is essential to follow the manufacturer’s instructions and to use the correct quantity of the cleaner. Failure to follow the correct procedure can cause damage to the system and reduce its efficiency.
Mistake 5: Using a Dirty DEF Tank
Using a dirty DEF tank can cause contamination of the cleaner and lead to ineffective cleaning. A dirty tank can also lead to clogging of the system and damage to the engine. It is essential to ensure that the DEF tank is clean before adding the cleaner. If the tank is dirty, it should be cleaned before adding the cleaner.
Mistake 6: Using DEF System Cleaner as a Fuel
The use of the DEF system cleaner as a fuel additive leads to serious engine damage. DEF system cleaner is specifically designed for use in the DEF system, not as a fuel additive. The use of the cleaner as a fuel additive can lead to corrosion and damage to engine components. Always use the cleaner as directed by the manufacturer.
Mistake 7: Not Disposing of the Used Cleaner Properly
Improper disposal of the used cleaner can cause harm to the environment. It is essential to dispose of the used cleaner in accordance with local regulations. The cleaner should be disposed of in a designated hazardous waste disposal facility.
How to use DEF Cleaner System?
A Diesel Exhaust Fluid (DEF) system cleaner is an important component of diesel engines equipped with a selective catalytic reduction (SCR) system. This cleaner is designed to remove contaminants and deposits from the SCR system, which helps to maintain the system’s efficiency and reduce NOx emissions. This article will discuss how to properly use DEF system cleaner.
Step 1: Check the Manufacturer’s Recommendations
Before using a DEF system cleaner, it is important to check the manufacturer’s recommendations. The manufacturer will provide instructions on how to use the cleaner, the recommended frequency, and the quantity required. It is important to follow the manufacturer’s recommendations to ensure the cleaner is effective and does not cause damage to the engine or SCR system.
Step 2: Prepare the DEF Tank.
To use the DEF system cleaner, the DEF tank must be empty. It is important to drain the DEF tank completely before adding the cleaner. If the tank is not empty, the cleaner may not be effective, and it could mix with the DEF fluid, which can cause damage to the SCR system.
Step 3: Add the DEF System Cleaner
Once the DEF tank is empty, adding the DEF system cleaner is time. The cleaner should be added directly to the DEF tank. Adding the correct amount of cleaner, as the manufacturer recommends, is important. Adding too much or too little cleaner can result in ineffective cleaning or damage the SCR system.
Step 4: Circulate the Cleaner
After adding the cleaner to the DEF tank, it is important to circulate it through the system. The engine should be started and run for several minutes to circulate the cleaner. The engine should be run at idle speed to ensure the cleaner is distributed evenly throughout the system.
Step 5: Allow the Cleaner to Work
After circulating the cleaner, it is important to allow it to work. The cleaner should be left in the system for at least 30 minutes or as the manufacturer recommends. This will give the cleaner time to dissolve deposits and contaminants in the SCR system.
Step 6: Drain the Cleaner
After allowing the cleaner to work, it is time to drain it from the system. The engine should be turned off, and the DEF tank should be drained completely. The cleaner should be drained into a container and disposed of according to local regulations. It is important not to reuse the cleaner, as it may contain contaminants that could damage the SCR system.
Step 7: Refill the DEF Tank
After draining the cleaner from the system, it is time to refill the DEF tank. Using fresh DEF fluid that meets the manufacturer’s specifications is important. The DEF tank should be filled to the appropriate level, and the system should be checked for leaks.
In conclusion, using DEF system cleaner is essential to maintain the efficiency of the SCR system and reduce emissions. You can hire clean diesel specialists. However, avoiding the mistakes discussed above is important to ensure effective cleaning and prevent damage to the engine and SCR system. Always use the recommended cleaner, follow the correct procedure, use the correct quantity, and dispose of the used cleaner properly. Regular use of the cleaner can help maintain the system’s efficiency and extend its lifespan.
