Diesel Exhaust Fluid (DEF) is one such product that has gained popularity recently due to its ability to reduce harmful emissions from diesel engines. This article will explain what DEF is, how it works, and its environmental benefits.
What is Diesel Exhaust Fluid?
Diesel Exhaust Fluid is a non-hazardous solution of urea and deionised water. It is used in diesel engines with Selective Catalytic Reduction (SCR) systems to reduce harmful Nitrogen Oxide (NOx) emissions. The NOx is broken down into harmless nitrogen and water vapour by the SCR system after injecting DEF into the exhaust stream.
Types of DEF Products Available:
DEF is available in various forms, including:
- Bulk DEF: This is the most common type of DEF and is sold in bulk quantities for use in commercial and industrial settings.
- Packaged DEF: Packaged Diesel Exhaust Fluid is sold in smaller quantities, usually in 2.5-gallon or 5-gallon containers, for use in passenger cars and light-duty trucks.
Features and Specifications of DEF:
Diesel Exhaust Fluid has the following features and specifications:
- Non-toxic and non-flammable
- Colourless and odourless
- The freezing point of 12 degrees Fahrenheit
- The boiling point of 220 degrees Fahrenheit
Uses or Applications of Diesel Exhaust Fluid:
- Reducing Harmful Emissions:
- Diesel Exhaust Fluid (DEF) reduces the harmful emissions of Nitrogen Oxide (NOx) from diesel engine exhausts.
- The DEF mixture reduces NOx emissions by converting them into harmless nitrogen gas and water vapour.
- Meeting Emission Standards:
- DEF is essential to meet emission standards set by the government in various countries.
- The Indian government has mandated the use of DEF in heavy-duty commercial vehicles manufactured after April 1, 2020.
- Improving Engine Performance:
- DEF also helps improve the engine’s performance by reducing fuel consumption and increasing power output.
- It also helps minimise soot formation and other harmful deposits, increasing the engine’s lifespan.
- Ensuring Compliance:
- Using Diesel Exhaust Fluid ensures compliance with various regulations and standards, avoiding penalties and fines.
- It also helps to improve the organisation’s reputation by demonstrating its commitment to environmental sustainability.
- Cost-Effective:
- Diesel Exhaust Fluid is a cost-effective solution to reduce NOx emissions as it can be used in existing engines with minor modifications.
- It also helps reduce maintenance costs and increase the engine’s lifespan, resulting in cost savings in the long run.
- Widely Available:
- DEF is widely available in various packaging sizes, making it easy to store and transport.
- It can be easily refilled at retail outlets, service stations, and maintenance centres.
Diesel Exhaust Fluid has become an integral part of the modern diesel engine ecosystem. Its use is essential to meet government regulations and reduce harmful emissions and improve engine performance.
Things to Consider When Buying DEF:
If you are looking to purchase Diesel Exhaust Fluid for your diesel engine, you should consider a few things to ensure that you get the right product for your needs. Here are some crucial factors to keep in mind:
- Quality: When buying DEF, ensuring you get a high-quality product that meets industry standards is essential. Look for DEF that meets the ISO 22241 standard, which ensures that the product is of consistent quality and free from impurities.
- Shelf Life: DEF has a limited shelf life, so checking the expiration date before purchasing is essential. Most Diesel Exhaust Fluid has a shelf life of around two years, so be sure to use it before it expires.
- Storage: DEF should be stored in a cool, dry place, away from direct sunlight and heat sources. Storing Diesel Exhaust Fluid in a hot or humid environment can cause it to break down and degrade, reducing its effectiveness.
- Quantity: When buying Diesel Exhaust Fluid, consider the amount you need based on your engine’s usage. Most diesel engines use DEF at a rate of around 2-3% of diesel fuel consumption, so you should be able to calculate how much you will need based on your engine’s fuel consumption.
