Exhaust Gas Recirculation (EGR) is an acronym meaning “exhaust gas recirculation.” Most manufacturers relied on EGR to comply with the first set of pollution standards in 2004 and 2007. Exhaust gas is cooled and regenerated through the engine in an EGR system. The cylinder’s combustion temperature is decreased, which reduces NOx output. However, because to the lower efficiency of the operating temperature, the cooler combustion creates more particulate matter. Furthermore, the engine is not running at its optimal combustion temperature, resulting in decreased fuel efficiency and engine output. An SCR system has the advantage of allowing the engine to operate at greater temperatures in order to improve performance while also lowering NOx levels.
SCR has a number of drawbacks, the most significant of which are logistical. DEF (Diesel Exhaust Fluid) must be added to the system as needed by SCR; consumption rates are determined by engine usage. DEF’s distribution infrastructure is still in its infancy, and while DEF is available in many spots around the country, it may be more difficult to obtain for operators in isolated areas. Because the new SCR systems take up more space on the chassis, bodybuilders and upfitters may have difficulty working around their packaging.
SCR system maintenance is simple and may be done at the same time as regular chassis maintenance. DEF filter replacements will most likely be measured in years rather than months, and will take only a few minutes.
The answer to this question will differ depending on the vehicle’s manufacturer and year. New instrument gauges and indications have been introduced to most vehicle dashboards and on-board displays. If the SCR is permitted to operate without DEF, the vehicle will display a gradual series of warnings and indicators, as well as performance losses. For further information, go to your OEM’s website (a list of OEM links is available on this site).
At high temperatures, DEF’s shelf life begins to deteriorate. It will progressively begin to create minor amounts of ammonia if kept at or above 120 degrees Fahrenheit. For further information on correct DEF handling in severe temperatures, contact your DEF supplier.
Diesel Exhaust Fluid (DEF) is an acronym for Diesel Exhaust Fluid. It’s made up of 32.5 percent chemically pure Urea and 67.5 percent deionized or demineralized water. It’s a non-hazardous, unregulated solution. It’s also known as NOx reduction agent AUS32 or AdBlue, both of which are widespread in Europe.
No, DEF is injected into the exhaust stream of a diesel engine. It’s kept in its own tank, which is normally right next to the diesel tank. To identify it as DEF, it usually has a blue cap or other blue sign (whereas diesel is often associated with the color green).
No, DEF is a stable, non-toxic liquid that does not require the use of a DOT-approved hazardous material placard to transport.
DEF weights about 9 pounds per gallon. DEF is a somewhat hefty product as compared to diesel fuel, which weighs around 7.05 pounds on average, and gasoline, which weighs about 6.19 pounds on average.
DEF should last a minimum of one year if stored between 10 and 90 degrees Fahrenheit.
Although DEF has a freezing point of +12 degrees Fahrenheit, it can still be utilized once it has thawed.
I’ve been hearing a lot about the importance of DEF purity. How can I tell if my DEF is pure and compliant?
The only way to tell for sure is to take a sample and send it to a laboratory for analysis. Many manufacturers, on the other hand, have gotten API (American Petroleum Institute) certified, which is a voluntary program that monitors DEF quality. Remember that DEF is a colorless, transparent liquid. If your DEF container has any color, haze, phase separation, or sediment, this should raise an urgent red alert.
Since 2006, SCR has been employed across Europe and has an established track record. In Europe, almost 600,000 SCR vehicles are in use, with more coming on the market every day.
No, DEF is a highly purified mixture of high-purity urea and deionized or demineralized water. To keep the product from clumping when dry, agricultural grade urea contains chemicals like formaldehyde.
No, Off-road diesel engine manufacturers are starting to embrace this technology early in order to fulfill EPA emissions limits in 2013 and 2014 and beyond. This leads to applications in locomotives, tractors, boats, and seagoing vehicles.
SCR technology has been reported to boost fuel efficiency by 4% to 9% by allowing diesel engines to operate at more efficient temperatures, in addition to the obvious environmental benefits.
Urea is a nitrogen molecule that, when heated, converts to ammonia. It is extensively used as fertilizer in agriculture.
DEF, on the other hand, will not “The metal of many storage containers (such as aluminum) will leach into the DEF and contaminate it, causing harm to numerous goods.
There are much more materials that are incompatible with DEF than there are materials that are. In the building of DEF equipment, stainless steel and DEF certified poly are regularly used materials. ISO 22241 specifies the materials that can be used in the storage and manipulation of DEF. The transfer and distribution of the Diesel Exhaust Fluid must be done with specially formulated DEF hose.
DEF is usually sold by the gallon, and prices in this new market have been volatile. Because the buyer is paying for the packaging as well as the commodity, packaged items (shelf goods) are frequently more expensive per gallon than bulk (from dispensers). DEF costs between $2 and $5 a gallon in Europe, where the market has had time to mature and distribution is more established.
Initial estimates put the consumption rate between 2% and 3%. For every 100 gallons of diesel fuel burned, for example, 2 to 3 gallons of DEF will be consumed. However, results will vary according on the engine make and model, and off-road vehicles may consume DEF at a higher rate while also gaining more fuel economy.
For on-road cars, we’ve seen tanks with capacities ranging from 4 to 28 gallons. The size and location will differ depending on the brand and model. For larger off-road vehicles that burn more fuel, larger tanks will be required. DEF tanks are built of poly or stainless steel that has been approved for use with DEF.
What is the best way to get rid of DEF that isn’t on the list?
Although DEF is not a dangerous material, you should consult your local government, municipal government, and environmental organizations to determine the right disposal technique. Your local water treatment facility and department of health and environmental control are two examples of these agencies. Also, for more information, contact your DEF provider.
Around DEF equipment and containers, I observe a white, chalky residue. Is this typical?
Yes, the urea returns to its solid, concentrated condition as the liquid evaporates from the DEF solution. (Think of salt water that has been allowed to evaporate, leaving a salt residue behind.) Sediment and other built-up deposits can be removed with a simple deionized water wash. This residue is commonly seen in nozzles.
DEF is available in a number of packaging options and bulk dispensing devices. Packaged foods, or what are usually referred to as “junk food,” are the smallest of these “Jugs.” The most prevalent packaged products sizes are 1 and 2.5 gallons, which are available at most truckstops and dealerships around the country. 55 gallon barrels are the next level up, which can be refilled or not. Hand pumps and electric drum pumps can be installed on top of the drums to dispense the product at a rate of 4-8 gpm. DEF is stored and transported in totes with capacities of 275 or 330 gallons. Pumps for dispensing are provided that mount on top or to the side of the tote. A digital flow meter is frequently included with tote pumps.
What color is exhaust fluid?
DEF (Diesel Exhaust Fluid) is an important component of meeting emission regulations. However, if any common vehicle fluids (including water) are unintentionally put to the DEF tank, the Diesel Exhaust Fluid will be polluted, causing system components to be damaged and rendering the system’s emission reduction qualities ineffective.
- DEF is typically clear, but it turns “light blue” when it comes into touch with copper or brass, and it turns “rusty” when it comes into contact with steel or galvanized steel.
- Due to the fact that DEF is heavier than diesel fuel and oil, these fluids will float on top of it.
If you believe that the DEF has been contaminated but can’t tell by smell or color, use a refractometer to analyze the fluid, or use a scan tool on select cars to do a DEF quality test.
What does DEF in diesel fuel look like?
32.5 percent high-purity synthetic urea and 67.5 percent deionized water make up diesel exhaust fluid (DEF). At 9.08 lbs. per gallon, DEF is slightly heavier than water (versus 8.34). It’s a transparent liquid with a little ammonia smell, despite marketing names like AdBlue and Blue DEF. Although DEF has a freezing point of 12 degrees Fahrenheit, it is safe to use if frozen and thawed because both urea and water freeze and thaw at the same rate. In severely cold temperatures, most vehicles include a DEF heating system to keep them operating. DEF is transformed to ammonia when pumped into the exhaust, which subsequently breaks down NOx into nitrogen and water.
Is Blue DEF really blue?
What Is BlueDEF Diesel Exhaust Fluid, and What Does It Do? DEF, or diesel exhaust fluid, is a critical component of the Selective Catalytic Reduction (SCR) process utilized by most medium and heavy-duty engine manufacturers to comply with EPA 2010 rules. BlueDEFTM is a harmless mixture made up of 67.5 percent purified water and 32.5 percent ultra pure automotive grade urea. BlueDEFTM aids in the conversion of NOx to nitrogen gas and water vapor, which are both safe and natural components of the air we breathe. BlueDEFTM is a colorless, odorless, and stable substance.
2. How much DEF is going to be used by my truck?
Every 300 miles, one gallon of BlueDEFTM is consumed. Between fill-ups, a truck with a 20 gallon DEF tank may travel up to 6,000 miles.
3. What happens if a truck runs out of DEF?
No. Running out of BlueDEFTM will not cause an engine to shut down or fail to restart. Engine horsepower will de-rate if the DEF tank is empty, hence BlueDEFTM should be added to the tank.
4. Does DEF freeze in the winter?
At 12 degrees Fahrenheit (-11 degrees Celsius), DEF begins to freeze. The engine will start and run normally if DEF freezes (no de-rate or malfunctioning lights). The fluid will be thawed for use by a DEF tank heater, which will have no effect on the engine’s operation.
5. Why are you doing this now?
The Environmental Protection Agency, OEMs, and several trucking fleets pledged to reduce NOx emissions in 2010 to help the environment. Most new trucks will be equipped with a Selective Catalytic Reduction (SCR) system to reduce NOx emissions. Diesel exhaust fluid is required for SCR technology (DEF).
Is there a difference between DEF and Blue DEF?
AdBlue and Blue DEF are really the same thing; they’re just different DEF brands. AdBlue and Blue DEF are just trademarked names used by two separate firms to advertise diesel exhaust fluid, or DEF, and they are very identical. DEF, or diesel exhaust fluid, is a specific fluid that is poured into a particular container and then pumped into the exhaust stream to reduce the amount of pollutants produced by diesel engines. It’s an aqueous urea solution that reduces nitrous oxide emissions from diesel engines.
What is green diesel?
On-road diesel is either clear or somewhat green in appearance. When diesel fuel is freshly dispensed into a bottle to observe its color, refineries add a green dye, which is visible. This dye fades to yellow or darker colors as the fuel ages. Checking the fuel for a “bright” appearance, with the faint green dye being a giveaway that the diesel is new and in good condition, is part of a visual inspection to assess diesel fuel quality.
What is dyed diesel?
Diesel contains dye in almost all of it. When we talk about dyed diesel, we usually mean a red dye applied to off-road diesel. Off-road diesel is typically used for heating oil, construction fueling, agricultural use, and other off-road equipment not needed to pay fuel taxes on the highway system.
What is farm diesel?
Off-road diesel, often known as farm diesel or diesel for agricultural purposes, is diesel that is not subject to on-road fuel taxes. Diesel fuel used for agricultural purposes is tax-free. Taxes can be avoided if diesel is burned on a farm and can be tracked. In Oregon, farms are able to obtain clear diesel without paying any road fees. It is frequently coloured red to indicate that it is tax-free. Some farms may track their use of clear diesel so they can submit for Federal road taxes for off-road usage in Oregon, where P.U.C. for trucks over 26,000 GVW pay a weight mile tax instead of a per gallon state road tax.
What color is dyed diesel?
Every gallon of fuel sold in the United States contains some color. Diesel for on-road use usually has a slight green hue. This is a dye that is mixed into the fuel by either the refiner or the terminal supplier. Off-road diesels are coloured red to indicate that the fuel is tax-free and intended only for off-road use.
Why is diesel dyed?
Diesel is coloured to indicate whether or not it has paid road tax. In the United States, on-road diesel usually has a faint green hue. Off-road diesel is dyed red to indicate that it has not paid the required road taxes in all states and by the federal government.
What is off-road diesel?
Off-road diesel is diesel fuel that has been dyed red to indicate that it is tax-free and only available for off-road fuel uses such as construction fueling, equipment that is never used on a public road, agricultural use, heating oil, boiler fuel, and other non-taxed diesel fuel uses as defined by state and federal fuel tax laws. Some off-road users in Oregon can use the Oregon state tax exemption to buy on-road fuel if they have the correct papers.
Is dyed or off-road diesel flammable?
The National Fire Code classifies off-road diesel as a Class II combustible liquid. A flammable fuel has a flash point below 100 degrees Fahrenheit. The flash point of diesel ranges between 126 and 205 degrees Fahrenheit (typically assumed to be about 160 degrees F). As a result, it’s classified as a Class II combustible.
Is off-road diesel or dyed diesel high sulfur diesel?
Dyed diesel (also known as off-road diesel) contains a lot of sulfur. Diesel fuel having a sulfur level of more than 500 parts per million is known as high sulfur diesel.
Is off-road diesel or dyed diesel ultra-low sulfur diesel?
Off-road and colored diesel fuels may have ultra-low sulfur, however this is not always the case. In the United States, there has been a persistent campaign to reduce sulfur in all fuels, led by EPA regulation. Off-road construction and agricultural equipment have been required by EPA rules in recent years to have an emissions system that allows ultra-low sulfur to function without serious difficulties. As a result, today’s off-road diesel is ultra-low sulfur. If you have a tank with old dyed red diesel fuel in it, you can infer it has a sulfur concentration that is higher than ultra-low.
What is dyed ULSD fuel?
Dyed ULSD fuel is ultra-low sulfur diesel that has been dyed red to indicate that it is only intended for off-road or untaxed use. Heating oil, construction fuel, agricultural fuel, generator fuel, and other off-road uses are common uses for this type of fuel. The abbreviation “ULSD” stands for ultra-low sulfur diesel.
Is dyed diesel #1 or # 2 diesel?
Diesel that has been dyed can be either #1 or #2 diesel. Both fuels must include a red dye to prove that they are untaxed and cannot be utilized as on-road fuels.
Why does the government require diesel be dyed red?
“For two reasons, the federal government demands dyeing of untaxed diesel fuel and kerosene. To aid in the reduction of tax fraud by recognizing fuel that hasn’t paid excise taxes and to aid in the reduction of air pollution by identifying fuel that isn’t acceptable for use in highway vehicles.”
Is dyed diesel and off-road diesel kerosene?
Kerosene (which crosses as #1 diesel fuel) can be found in dyed diesel and off-road diesel, but it is not always the case. Do not mistake a dyed fuel for kerosene, which is a more uncommon fuel. Kerosene differs from #1 diesel in one way: it has been proven that it may be absorbed and taken up by a wick. All kerosene is classified as #1 diesel. Kerosene isn’t found in all #1 diesel fuels. Diesels that have been colored and off-road fuels are in the same boat. All coloured kerosene and off-road diesel are dyed. Kerosene isn’t the only coloured fuel.
Is dyed diesel and off-road diesel stove oil?
Stove oil is coloured diesel and off-road diesel. Similar to diesel, it’s usually a #1 or #2 stove oil. Stove oils, as opposed to diesel, had a slightly distinct set of specification problems in the past, which is why they were named “stove oils.” It was less precise when petroleum refineries distilled crude oils to make diesel range fuels than it is now with hydrocracking technology. The number of distillate range fuel requirements is significantly more concentrated today, thanks to both oil refinery technologies and EPA emission standards, in order to assure compliance with EPA and state rules. If your heating appliance requires stove oil, it will most likely require #1 stove oil or #1 kerosene. This product is supposed to produce less soot, making it better suited for use in a pot stove. Monitor and Toyostove thermostatically controlled direct vent heaters are the most current stove oil appliances in the United States.
Is off-road diesel bad for my truck?
It depends on the year of your truck, and we’re assuming you’re talking about red diesel fuel. To begin, it is illegal to use dyed diesel, off-road diesel, or heating oil in an on-road vehicle. If you are found in Oregon, you might face a punishment of up to $10,000, and the state is very aggressive in pursuing tax evasion. Beyond the usage of off-road fuel, which is legal. On the west coast, coloured diesel is often ultra low sulfur fuel. This means that if it’s burned in your engine, it won’t cause any problems. It may be high sulfur or low sulfur fuel, depending on the age of the colored fuel or whether it is genuinely a heating oil. If you use that fuel in a post-2007 engine with a particle trap, you’ll have major maintenance problems.
Is dyed diesel or off-road diesel heating oil?
Yes, colored diesel and off-road fuel can be used to heat your home. These days, most dyed diesel and off-road diesel is ultra-low sulfur diesel. According to the EPA and most state rules, heating oil can have a low or high sulfur concentration. So, while heating oil cannot always be colored diesel (when used for off-road machinery or agricultural purposes), dyed/off-road diesel can always be used for heating oil and meet the requirements of heating oil furnaces.
Does off-road diesel freeze?
At low temperatures, off-road diesel gels. Wax crystals form and fall out of the diesel at lower temperatures, clogging filters and gelling the fuel. Water and naturally held-in diesel will also ice up, clogging filters. Diesel gelling is the term for this phenomena.
Does off-road diesel gel in cold weather?
If it gets cold enough, all diesel fuels will gel. Wax crystals and ice accumulating in your fuel will clog filters and cause your equipment to shut down. As a rule of thumb, if you don’t treat your diesel fuel, it should work OK above 20 degrees F. If the temperature drops below 20 degrees Fahrenheit, make sure your vendor treats the fuel for winter use so it can operate at -20 degrees Fahrenheit. If you’re going to be operating in temps below that, check with your vendor to see if they’ve tested the fuel to work in temperatures below -20 degrees F.
Does off-road diesel go bad?
Off-road and dyed diesel might deteriorate with time. All ASTM-compliant diesel fuels should be safe to store for up to a year without extra treatment or testing. If you’re storing diesel for a long time, it’s a good idea to treat it with a biocide and an oxidative stabilizer to guarantee that it stays within specifications and that nothing grows in your fuel tank. Water and dirt entering the fuel through a tank vent is the worst opponent of long-term diesel storage. A tank will breathe when the temperature changes, bringing in air and moisture from the outside. Keeping your gasoline within specification means making sure there’s no water in the tank and that no outside impurities can get in.
How long can I store off-road or dyed diesel in a fuel tank?
Diesel fuel has a one-year shelf life if left untreated. You can anticipate diesel to last two to three years if it is treated with a biocide to prevent biological development in the tank. When diesel is sampled after two to three years, it loses its brightness and begins to exhibit signs of age. After three years, you’ll want to sample and test the fuel to make sure it’s up to code and safe to use.
What is the difference between off-road diesel and on-road diesel?
The significant difference between the two fuels is the amount of gasoline taxes levied. To indicate that it is both ultra-low sulfur diesel and that the on-road fuel taxes associated with using it to power a highway vehicle have been paid, all on-road diesel is transparent or greenish in color. Fuel that has been dyed has not been taxed and cannot be used to power a vehicle on a public road.
Do you pay sales tax on dyed diesel or off-road diesel in Washington state?
Yes. The sales tax is charged if you consume dyed diesel and do not pay the on-road fuel taxes in Washington state. The sales tax is not paid if you use clear fuel with road taxes connected to it. The Washington Department of Revenue has more information about Washington gasoline taxes.
What are the taxes on dyed diesel or off-road diesel in Oregon state?
Your gasoline distributor pays a modest tax (less than $.01) on the fuel they purchase at the wholesale terminal. The US EPA Superfund cleanup and the “LUST” (Leaking Underground Storage Tank Cleanup Fund) are two of the taxes. Aside from that, there are no taxes on off-road diesel fuel in Oregon (federal, state, or local municipality).
Is there a way to buy clear diesel without a road tax on it?
In Oregon, you can purchase clear fuel that is exempt from state road charges. The following are the requirements for using clear diesel in Oregon without paying state taxes:
- cars with a legal Oregon “E” plate and registered to a US government agency, an Oregon state agency, or an Oregon county or city
- Vehicles or farm tractors/equipment that are only used on the roadway inadvertently, as specified in ORS 319.520
- Unlicensed vehicles or equipment that are utilized exclusively on privately owned property
What happens if I use dyed diesel in an on-road vehicle?
If you are caught in Oregon, you might be fined $10,000 each day. We’ve seen fuel tax evaders nabbed before, so be advised that Oregon is looking for any amount of dye in an on-road vehicle’s saddle tank. You will have maintenance concerns with your vehicle’s emission system if you use low sulfur or high sulfur fuel and your vehicle has a particulate trap.
Can you use dyed diesel in a diesel pickup truck?
Only if the pickup is solely for off-roading. If you plan to utilize that truck on a public road (even to cross a street) and colored fuel is discovered in it, state regulators can (and do) levy fines of up to $10,000 per occurrence. You can use off-road diesel as the vehicle’s fuel if you have a closed facility or a large farm and are not registering the vehicle for on-road use (thus the pickup must not leave the site). Any regulator observing dyed fuel in your vehicle will assume it’s an on-road pickup if you have license plates and it’s approved for on-road use.
How does the government test if someone used dyed diesel?
Typically, regulators may take a sample from the tank or spin the gasoline filter to look for obvious dyed fuel when checking for illegal usage of dyed fuel. If the fuel is clear (or even slightly pink) and they suspect dyed fuel was used in the car, they can use a special black light to show that dyed fuel was in touch with the vehicle. They’ll beam the light on the gasoline filter, the fuel tanks, and other portions of the engine compartment that may have come into contact with the fuel. They will cite the vehicle operator if they detect even a minor trace of the red-dye used in off-road fuel in specific regions. On the internet, there are kits for filtering dye out of gasoline to eliminate the color. Those kits won’t be able to remove enough dye to keep these lights from detecting it.
Why is off road diesel illegal for pick up trucks to use?
Off-road diesel is painted red to indicate that on-road fuel taxes have not been paid or that the fuel is tax-free. Fuel taxes for on-road fuel usage are levied by the federal government and state governments to help pay for the roads we all use. Fuel taxes are deductible if you use diesel for non-road equipment, machinery, or heating/boiler uses, and the fuel is coloured to make its tax-free status obvious. In a roadside or site level inspection, regulators can also shine a black light on certain parts of a vehicle’s system to see if colored gasoline is being used illegally.
What is the difference between dyed diesel and heating oil?
What’s going on in the Pacific Northwest right now? Typically, nothing. Diesel-colored heating oil is used. To reduce the overall cost of the fuel, most petroleum distributors sell the mainstream colored diesel grade for use as heating oil. Heating oil and dyed diesel have varied ASTM requirements depending on where you acquire it. Because furnaces and boilers can manage dirtier, lower-quality fuels than off-road equipment with a particle trap, heating oil specifications have larger tolerances than diesel criteria. Although heating oil is always a diesel fuel, dyed diesel for off-road machinery may have a distinct specification. In Oregon, for example, any dyed diesel fuel used in off-road equipment must include at least 5% biodiesel or renewable diesel. Heating oil and boilers are excluded from the biofuel mandate. Heating oil, on the other hand, can be free of biodiesel, while off-road diesel for machinery cannot.
Can refrigerated trailers or “reefers use dyed diesel even if they are attached to a truck moving it on the highway?
Refrigerated trailers are, in fact, off-road vehicles. Because its engine is not pushing something along the road, the diesel-fueled refrigeration trailer is considered off-road equipment. Any ultra-low sulfur diesel fuel can be used in these trailers (dyed or clear). If you use on-road clear fuel in a refrigerated trailer and keep track and verification of the on-road fuel used in the off-road piece of equipment, you can get your fuel taxes returned. However, proof is required, so speak with your CPA or accountant.
What does diesel exhaust fluid do?
We get a lot of questions about DEF and how to use it effectively on your forecourt, so we asked the expertise of Danny Seals, a forecourt solutions expert, to provide us with some simple answers.
What is DEF?
DEF is a urea-water solution that is injected into the exhaust stream of diesel automobiles to convert NOx gases (harmful emissions) into nitrogen and water. Vehicle manufacturers introduced a Selective Catalytic Reduction (SCR) technology to meet EPA emissions limits in 2010. This is a strategy to achieve the requirements without sacrificing engine performance or fuel economy. DEF isn’t a fuel additive, and it’s kept in its own tank.
Who needs DEF, why?
DEF is required for medium and heavy-duty vehicles equipped with diesel engines manufactured after 2010. To meet emissions rules, the vehicle is configured to inject DEF into the exhaust stream. The engine performance will be diminished and lower speeds will be imposed if the vehicle is allowed to run out of DEF.
What are the different delivery modes of DEF?
DEF is available in a variety of forms. A driver can purchase jugs/containers in a variety of sizes. This necessitates the driver physically transferring the DEF into the car. When installed, DEF can also be dispensed into the vehicle using a fueling dispenser.
Which retailers should offer DEF and what indicators can they use to decide?
Because there is such a vast population of automobiles on the road, DEF is an excellent product for all c-stores to offer. Retailers who sell diesel at their gas stations can utilize the volume sold to estimate the number of diesel customers they have. DEF is required by the majority of today’s heavy-duty trucks. Locations with a separate large truck filling station might think about putting DEF in the dispensers. Because they buy DEF in quantity to keep in their tanks, this results in higher profit margins. Some places that sell a lot of diesel on their forecourt should also consider a dispenser option.
How can Gilbarco help retailers get into DEF?
Since the inception of DEF requirements, Gilbarco has been the industry leader in DEF dispensers. Over the years, we’ve worked with large stores to provide dispenser functionality, and we’ve established the industry standard for this service. Gilbarco assists merchants in entering the DEF dispensing market by providing factory-installed options and retrofitting existing dispensers where DEF is stored in bulk.
What dissolves DEF crystals?
A small amount of Diesel Exhaust Fluid (DEF) spilled can be cleaned up or rinsed away with water. It will transform into white crystals if left to dry. Water can be used to remove them.
Will DEF hurt a diesel engine?
To meet EPA pollution rules, most new diesel trucks are fitted with selective catalytic reduction (SCR) systems that utilise diesel exhaust fuel (DEF).
What is a SCR system?
A catalyst reacts with engine exhaust to break down ecologically hazardous exhaust components in the SCR system. Injector nozzles, in a nutshell, spray controlled dosages of DEF into the exhaust. The DEF vaporizes and decomposes into ammonia and carbon dioxide, which mix with the nitrogen oxide in the exhaust to produce the harmless nitrogen and water byproducts.
First of All
DEF fluid is only for vehicles with the SCR system, therefore don’t try to use it on an earlier truck. Although this may seem self-evident, uninformed owners and even well-intentioned service station attendants and technicians at non-diesel shops have mistakenly assumed that because DEF is so wonderful for new diesel trucks, it must also be good for older diesel trucks.
Despite the fact that measures have been put in place to keep diesel fuel separate from DEF, it still happens: DEF is placed into the diesel tank by accident, or diesel is poured into the DEF tank by accident. When this happens, it’s more than a little annoyance: it can result in major damage and pricey repairs.
A fill port, a tank, and lines from the tank to the SCR and injection nozzles make up the DEF system. The dispensers should be properly labeled, and the DEF tank’s fill port, which has a blue cap, is designed to be smaller than the diesel tank’s fill port, preventing the diesel nozzle from being inserted into the DEF tank’s fill port.
Non-DEF chemicals are detected by SCR systems, which include built-in warnings. If non-DEF enters the SCR catalyst, the driver will receive a warning and a code indicating approaching SCR interruption.
What Happens If I Put Diesel into a DEF Tank?
Because diesel is lighter than DEF, it will float on top of it. If it gets inside the SCR catalyst, it can cause substantial damage, necessitating service or, worse, a (expensive) catalyst replacement. Before replenishing the DEF tank, it should be drained and thoroughly cleaned with deionized water. A single teaspoon of a foreign contaminant can contaminate a full tanker load of DEF.
What Happens If I Put DEF into a Diesel Tank?
You remove the fuel cap and open the fuel filler door, and your brain goes into automatic mode.
Putting DEF in the diesel tank is a simple error that could result in a truck being towed to the junkyard.
Because DEF is made up of urea and water, the entire tank of fuel becomes contaminated right away. Long-term implications will ensue if the engine is started and the diesel and DEF combination is introduced into the engine.
The DEF fluid crystallizes once the engine is started, causing irreversible damage… and the repair might cost as much as $12,000.
DEF corrodes and damages a variety of metals, including carbon steel, brass, aluminum, copper magnesium-nickel, and zinc.
What happens if you put a little DEF in diesel tank?
Owners and operators of trucks must not allow even a trace of DEF to enter their diesel tanks. The diesel fuel system will be contaminated as a result of this. A slight lack in judgment could lead to a vehicle’s demise. DEF, when used properly, makes the environment much cleaner.
