How does DEF fluid work is crucial in understanding the benefits it has for your vehicle. Its importance can be understood by its widespread adoption in the automotive industry’s efforts to produce cleaner and environmentally responsible vehicles.

Diesel Exhaust Fluid (DEF) helps reduce harmful nitrogen oxide (NOx) emissions from diesel engines by converting them into harmless nitrogen and water vapor through a process known as Selective Catalytic Reduction (SCR). DEF in diesel engines is largely driven by regulatory pressures aimed at mitigating the environmental impact of nitrogen oxides (NOx) emissions.

Governments may offer incentives for adopting cleaner technologies or impose penalties for non-compliance with emission standards. International agreements, such as the Kyoto Protocol and the Paris Agreement, further commit countries to reduce greenhouse gas emissions.

By reducing the formation of harmful pollutants in the exhaust system, DEF also contributes to extended engine life and reduced maintenance costs.

So, how does DEF work? And what benefits does it have for your vehicle? 

The Role of Diesel Exhaust Fluid in Emission Reduction

Diesel Exhaust Fluid primarily reduces nitrogen oxides emissions in diesel engines through a process called Selective Catalytic Reduction. 

In the presence of the catalyst, ammonia reacts with nitrogen oxides (NOx) in the exhaust gas. The reaction converts NOx into nitrogen (N₂) and water vapor (H₂O). These byproducts are harmless and inert gasses, making the exhaust emissions environmentally friendly.

“ The adoption of DEF in diesel engines stems from increasingly stringent environmental regulations imposed by governments worldwide. Research linking NOx emissions to respiratory diseases and other health problems has prompted regulatory bodies to prioritize NOx reduction in emissions. 

The SCR technology, enabled by DEF, has become a vital component in meeting these regulatory pressures, helping achieve cleaner air and environmental sustainability.

What is Diesel Exhaust Fluid (DEF) Fluid Made of?

So, what is DEF fluid made of?

The fuel is essentially a solution composed of approximately 32.5% urea and 67.5% deionized water. Urea is a key component in DEF because it is essential for the Selective Catalytic Reduction (SCR) process. 

When urea is injected into the hot exhaust stream, it undergoes thermal decomposition to produce ammonia (NH₃), a crucial reducing agent in the SCR catalyst.

Deionized water is used as the carrier for urea in DEF. It ensures that urea is adequately dissolved, forming a homogeneous solution. 

“ The high water content helps lower the freezing point of DEF, preventing it from crystallizing in cold temperatures. This is crucial for ensuring the proper functioning of the DEF system in a variety of environmental conditions.

Now that we understand what is DEF, and its composition, the question of how DEF fluid works remains unanswered.

How Diesel Exhaust Fluid Works in a DEF System

It’s true that DEF helps reduce harmful emissions from diesel exhaust engines, but how does the DEF system work?

The Science Behind Selective Catalytic Reduction (SCR) Technology

The answer lies in its pivotal role in the SCR process by providing the necessary ammonia to facilitate the reduction of nitrogen oxides in the exhaust gasses. 

It is stored in a separate tank in the vehicle and injected into the hot exhaust stream before it reaches the diesel particulate filter. The high temperatures in the exhaust system cause the urea in DEF to undergo thermal decomposition, breaking down to ammonia (NH₃) and carbon dioxide (CO₂).

In the presence of the catalyst, ammonia reacts with nitrogen oxides (NOx) in the exhaust gas. The reaction converts NOx into nitrogen (N₂) and water vapor (H₂O).

” DEF injection isn’t a ‘one-size-fits-all’ approach. The amount of DEF added to the exhaust stream actually varies based on a bunch of factors. Think of it like your car’s computer carefully calculating the perfect dose! It considers things like the engine’s temperature, how hard it’s working, and even the amount of harmful NOx emissions present. This ensures just the right amount of DEF is used to convert those emissions into harmless nitrogen and water vapor, keeping your engine running clean and efficiently.

Components of the SCR System

DEF is stored in a separate tank, which is equipped with level sensors to monitor the DEF fluid level. DEF injectors deliver the precise amount of DEF into the exhaust stream.

The injection occurs upstream of the selective catalytic reduction (SCR) catalyst.

When the engine is running, the engine control unit (ECU) determines the optimal amount of DEF required for NOx reduction based on inputs from NOx sensors.

“ NOx sensors are strategically placed in the exhaust system to monitor the concentration of nitrogen oxides. These sensors provide real-time feedback to the engine control unit (ECU) to optimize DEF injection for efficient NOx reduction.

The SCR catalyst is a crucial component made of materials such as titanium or vanadium. Exhaust gases pass through the catalyst, converting nitrogen oxides into harmless nitrogen and water vapor. 

Environmental Benefits of DEF

The usage of DEF in diesel engines is a response to stringent environmental regulations set by organizations like the Environmental Protection Agency (EPA) and other regulatory bodies worldwide.

DEF must meet strict quality standards to ensure its effectiveness in reducing nitrogen oxide (NOx) emissions. Maintaining high purity and quality in the production process of DEF can increase costs.

“ The adoption of DEF in diesel engines has a significant positive environmental impact, by substantially reducing NOx emissions. NOx emissions, when released into the atmosphere, can contribute to the formation of acid rain and smog that have detrimental effects on ecosystems, water bodies, and soil quality.

Reduced air pollution from diesel engines also has a positive impact on vulnerable populations, including children, the elderly, and individuals with pre-existing health conditions.

Comparative Analysis: DEF in Diesel Engines vs. Petrol/Gasoline Engines

Diesel and petrol engines differ in their combustion processes and, consequently, their emission profiles. Diesel engines tend to produce higher levels of nitrogen oxides (NOx) and particulate matter, while petrol or gasoline engines typically emit more carbon monoxide (CO) and hydrocarbons (HC). 

Petrol engines commonly use catalytic converters to reduce CO, HC, and NOx emissions. These devices effectively convert these pollutants into less harmful substances.

“ The Selective Catalytic Reduction (SCR) technology, facilitated by DEF, is particularly effective in reducing NOx emissions. Diesel engines, with their higher NOx output, benefit significantly from this technology. 

While both types of engines employ various technologies to reduce emissions, the distinct combustion characteristics of diesel engines make DEF a crucial component for achieving cleaner and more environmentally friendly diesel engine operation.

A chemical reaction occurs within the SCR system when DEF is introduced into the exhaust. As the vehicle heats up, the urea transforms into ammonia (NH3), an alkaline compound of nitrogen and hydrogen. Diesel Exhaust Fluid (DEF) freezes at 12°F (-11°C). Depending on the specific car and the type of fuel used, DEF can contribute to reducing NOx emissions by an impressive 70-95%.

An important question arises: At what temperature does DEF freeze, and how can we keep the DEF from freezing? Proper knowledge is essential because neglecting DEF freezing can lead to several engine problems and increased harmful emissions.

“ DEF (Diesel Exhaust Fluid) can solidify in low temperatures, posing a risk to the Selective Catalytic Reduction (SCR) system’s function. The exhaust filtration systems become less effective in the cold due to the frozen DEF, causing a ten-times rise in harmful vehicular emissions.

Common Misconceptions About DEF Freezing Point

There are a few common misconceptions about Diesel Exhaust Fluid (DEF) freezing that are important to clear up. So, let’s discuss them:

Frozen DEF Does Not Convert to its Normal State

There is a misconception that when Diesel Exhaust Fluid (DEF) freezes, it causes permanent damage and does not return to its regular status. However, the fluid can often return to normal once it melts or unfreezes.

Frozen DEF Instantly Loses Emission-Reducing Ability

Another common misunderstanding regarding DEF in cold weather is the belief that frozen DEF instantly loses its ability to reduce emissions. However, it’s important to note that proper thawing and preventive measures can often restore DEF functionality.

DEF Freezing Does not Impact Engine Performance

Some may mistakenly believe that DEF freezing in cold weather has no impact on engine performance. They overlook possible issues with the Selective Catalytic Reduction (SCR) system. The frozen DEF can impact engine performance by hindering the optimal operation of the SCR system, which is vital for reducing emissions. It may disrupt the system’s ability to convert harmful gases effectively, especially if the DEF tank heater is not utilized.

DEF Freezing Can Never Be Controlled in Cold Weather

It’s a misconception that DEF constantly freezes in cold weather and cannot be controlled. However, vehicles with heated DEF systems and proper storage often prevent freezing-related issues.

DEF Freezing Point: At What Temperature Does DEF Freeze?

DEF has a lower freezing point than water due to the ratio of urea (a synthetic nitrogen compound), which can lead to DEF issues if not managed properly. It freezes at 12 degrees Fahrenheit (-11 degrees Celsius). The urea concentration allows both parts of the compound to freeze at the same temperature and helps them thaw at the same rate without degrading the product.

“ Diesel exhaust fluid can freeze in storage containers and a vehicle’s tank. However, freezing will not compromise the quality of the DEF unless it remains frozen for a longer period. If DEF freezes in the tank, it will melt with the rise in temperature without affecting the operational effectiveness of the vehicles.

Consequences of DEF Freezing

In winter, frozen DEF can stall your trucking operation completely. DEF freezing can lead to the following consequences:

• Frozen DEF can hinder the Selective Catalytic Reduction system’s ability to convert harmful emissions.

When we neglect the cleanliness of the diesel fuel filter, the engine won’t perform well, it’ll guzzle more fuel, and we might end up with severe engine damage. On the flip side, the diesel fuel filter does precisely what it says: it filters out impurities from the diesel fuel, ensuring only clean gasoline enters the engine. 

Therefore, a proper route planning for slowing wear down and with a fuel filter cleaning involves regular maintenance. Knowing how to clean a diesel fuel filter can be essential to keep your engine running smoothly. Additionally, diesel-delivery services can make refueling easier, ensuring the engine is never left high and dry. 

Now, let us break down each stage of cleaning a diesel fuel filter to ensure the engine remains in a premium condition.

What Is A Diesel Fuel Filter?

A diesel fuel filter is vital to a diesel engine’s fuel system. It removes contaminants and impurities from the fuel, safeguarding the engine’s performance and durability by keeping harmful particles out of the fuel system. Diesel fuel often contains pollutants that, if unfiltered, can clog fuel injectors, harming the fuel’s quality. 

These contaminants include:

• Dirt and Debris – Unwanted particles from refueling or present in the tank.
• Water – Moisture in the tank leads to microbial growth, rust, and corrosion, harming the engine
• Microbial Growth – Bacteria and fungi thrive in fuel tanks with a hint of water, creating sludge and clogs. 
• Rust and Corrosion – Tank corrosion generates contaminating particles in the fuel.

With its housing and replaceable filter element, the filter captures and holds these contaminants, ensuring clean diesel fuel passes through and shields the fuel injectors. 

Diesel fuel filter costs fluctuate based on the vehicle and equipment’s make, model, filter brand, and type. Filter elements usually range from $10 to $30, whereas specialized or high-performance filters may be pricier.

Purpose of A Diesel Fuel Filter 

Other than preventing contaminants from damaging critical engine components such as fuel injectors and pumps, the diesel fuel filter has many purposes, such as:

1. Protecting Fuel Injection System – Diesel engines nowadays have high-pressure fuel systems with tiny fuel injector openings that need to stay clean. If dirty fuel gets in, it can clog these openings, reducing engine performance and leading to expensive fixes.
2. Improving Fuel Efficiency – Clean fuel is essential for efficient combustion in a diesel engine. A clogged or dirty fuel filter can restrict fuel flow, leading to incomplete combustion and reduced fuel efficiency.
3. Extending Engine Life – By preventing contaminants from entering the engine, a diesel fuel filter helps extend the life of the engine components and reduces the risk of costly repairs.
4. Maintaining Emissions Compliance – Diesel engines must follow emissions rules, and having a fuel filter to keep the gasoline supply clean is crucial to staying within those standards. 
5. Preventing Water Contamination – Diesel fuel can soak up moisture from the air, resulting in water buildup in the tank. This can lead to rust and nasty stuff growing in the fuel system. A fuel filter with a water separator can stop that from happening.

Using these lubricants and automotive fuels is very important as lubricants keep the engine running, and automotive fuels such as DEF play a huge role in controlling harmful emissions in the air we breathe due to diesel fuel engines. It, however, makes us wonder, while having a great demand, why is DEF so expensive?

DEF is costly because of the high price of urea, its main ingredient, and the impact of fluctuating global supply chains. This article will help you discover why there has recently been a significant increase in the price of DEF.

What is DEF?

Diesel Exhaust Fluid (DEF) is a clear liquid that consists of a mix of two significant liquids: urea and water. DEF is used in diesel engines to neutralize the emissions produced by nitrogen oxides (NOx) into harmless gases.

It also helps increase the efficiency of diesel engines while lowering their temperature while running.. It is a highly important fluid that hugely impacts companies running on diesel fuel.

Why is DEF so expensive?

According to the American Petroleum Institute, DEF is a mixture of urea 32.5 percent and deionized pure water 67.5 percent.

The United States Environmental Protection Agency has made it mandatory for any machinery or vehicles that have a diesel engine to use DEF since 2010 to reduce harmful emissions in the air we breathe.

Since urea is in high demand, it is synthetically produced on a large level with different quality grades. DEF, however, uses high-grade Urea, which is quite expensive and significantly contributes to the increase in the price of DEF. 

“ You can maintain a supply of high-quality DEF for your business by opting for Fuel Logic. You are just one call away from getting nationwide delivery of fuel such as diesel, gasoline, and DEF directly to equipment/trucks, into bulk tanks, or generators.

Another reason why there has been an increase in diesel exhaust fluid prices is in recent years; several factors have affected the price of urea. These factors are mentioned below:
 

• Supply issues: Urea that was exported from China to the west coast of the US has stopped because China has decreased its production due to its harmful effects on the environment, as most production happened near areas with human settlements. Hence, this decrease in supply will maintain its impact on pricing.
   
• Impact of urea pricing on DEF pricing: urea prices have fluctuated since 2021. According to the United States Department of Agriculture, urea prices increased by 149 percent by December 2021. It is observed that the prices have dropped after that but at a very slow rate and are still higher than they were before 2021.
  
• Effect of Ukraine/Russia war: Due to the war, the price of natural gas has increased, parallel to the cost of urea, causing it to rise. The price of DEA-grade urea, which is used in making DEF, also increased as Russia, the top exporter of fertilizer products, stopped its supply. The war is negatively affecting the price of urea and will possibly have the same effect on it in the future.
  
• Impact of drastic changes in urea prices over time: While the supply of urea is not meeting the market demands as much as it should, the costs will tend to stay higher and unstable even in 2023, according to jobbersWorld.
  
• Tariffs imposed by the American government in 2018: Tariffs were imposed on China to import urea, causing a supply chain issue. However, this gap was filled by other countries such as Nigeria, Trinidad, and Russia, which were again affected by the Ukraine/Russia war. These tariffs were later removed from urea imports from Russia and Trinidad.
  

How to avoid the changes in the price of DEF?

Now we know the reason why DEF is so expensive. It is important to understand that it is due to all the issues mentioned earlier related to urea. Hence, here are some ways we can adopt to avoid the changes in prices as long as we can or the worst-case scenario, prevent a shortage of DEF:
 

• Have a sufficient supply of DEF: As a business, you should devise smart ways to decrease costs. Hence, the best you can do is increase your storage capacity of DEF so you have the optimal supply for as long as DEF can last. Don’t forget to store it in the optimal conditions required, as DEF can have a year’s shelf life but can be prolonged if stored properly.
  
• Increase the storage capacity: this can be done by storing the maximum amount of DEF in your inventory. Its capacity can be increased to do that. It may be expensive for your business, but it will help you in the future to avoid price changes. They don’t affect your business as long as you have redundant supplies.
  
• Automated contact with the supplier: Since DEF shortage is possible. It will help if a business maintains the DEF supply so its shortage does not instantly impact the business. You can place your order at Fuel Logic DEF order page to avoid supply issues, as we provide hassle-free delivery nationwide.
