Diesel exhaust fluid
What is Diesel exhaust fluid (DEF)?
Diesel exhaust fluid or DEF is designed for use in diesel engines with SCR systems, which have proven to reduce 90% of emissions of nitrogen oxides. The Environmental Protection Agency explains. It will be injected into the exhaust gas, chemically reacting with NOx, converting it into harmless nitrogen and water vapor. In doing this, it brings cleaner emissions and better air quality.
Without DEF, the SCR system cannot do this conversion effectively, which leads to an increase in NOx emissions and failure to meet the emissions standards. DEF is quite similar to a cleaning agent for an exhaust system that allows diesel engines to operate with less environmental pollution.
How do you correctly fill the diesel exhaust fluid in your vehicle?
Keeping your vehicle’s DEF tank filled ensures optimal engine performance and compliance with emission regulations.
Here’s a guide on how to properly refill DEF in your car. Also kindly refer to the individual vehicle manual for topping Adblue.
Step 1: Find the Tank Position of the DEF
A blue cap typically indicates the DEF tank. Depending on the type of vehicle, the DEF filler opening might be:
– Beside the diesel fuel,
– Under the hood,
– Behind the rear or back of the vehicle
Step 2: Choose the Right Diesel Exhaust Fluid
DEF’s topping-off process should use fluid certified by ISO 22241 to ensure purity and composition. Impure DEF can bring down the whole SCR system. It is always expensive to correct such problems.
Step 3: Prepare for Refill
Make sure to follow these precautions:
– Wear gloves to avoid skin irritation.
– Avoid spills, as DEF can corrode certain surfaces if it dries.
– Check the fluid level on your dashboard
Step 4: Refill the DEF Tank
Step 5: Secure the Cap and Clean Up
– Close the DEF cap tightly to prevent contamination.
– Wipe any spills immediately with water to avoid crystallization.
– Dispose of the empty DEF containers properly following the local disposal guidelines.
The Future of Diesel Engines and Emissions Compliance
As per the global standards, DEF will be vital to ensure that diesel engines are compatible with environmental regulations. The adoption of DEF has helped diesel engines take a positive shift in perception regarding their capability to have lower emission levels and contribute toward clean air. In the future, SCR systems and usage of DEF can continue to become more efficient as technologies advance to help diesel-powered vehicles and machinery reduce their environmental footprints.
Additional Tips for Maintaining Your DEF System
✔ Store DEF properly with minimum direct sun and extreme temperature.
✔ Use fresh DEF- DEF’s shelf life is around 12 to 24 months; do not use a liquid past that.
✔ Never mix various DEF brands in a vehicle because different DEFs may have impurities and lower their quality.
Monitor DEF levels regularly. Running out of DEF means your vehicle could end up in limp mode, reducing performance. By following these easy steps, your diesel vehicle will operate efficiently and in complete harmony with emissions laws.
