Diesel Exhaust Fluid (DEF) also known as AdBlue®, is a non-toxic, colourless, odourless and non-flammable fluid. … It enables Land Rover to meet EU6 emissions legislation by reducing the levels of nitrogen oxide (NOx) emitted from the exhaust system by up to 90%.
Beside above, how do you put diesel exhaust fluid in a Range Rover?
Considering this, what does diesel exhaust fluid do? Diesel Exhaust Fluid (DEF) is a solution of urea and water that’s injected into the exhaust stream of diesel vehicles to turn NOx gases (harmful emissions) into nitrogen and water. This system is called a Selective Catalytic Reduction (SCR) implemented by vehicle manufacturers to meet EPA emissions standards in 2010.
Additionally, what happens when a diesel runs out of DEF? When DEF runs out entirely, the light turns red, and the truck is electronically limited from going more than five mph. DEF levels can also be checked manually. The storage tank can typically be found next to the diesel fuel saddle tank on a truck, or in the spare tire area of a passenger vehicle.
Subsequently, how much does DEF fluid cost? DEF, available at most service stations for $6 to $10 per gallon, is a fluid consisting of urea and deionized water in a 1:2 solution. It’s contained in a reservoir separate from the fuel tank and is metered into the engine’s exhaust stream to control certain emissions.For example, for every 100 gallons of diesel fuel consumed, between 2 and 4 gallons of DEF will be automatically injected into the exhaust system. The typical DEF tank will be approximately 15 – 20 gallons, thus requiring a fill every 5,000 to 6,000 miles.
Is all diesel exhaust fluid the same?
DEF fluids all must meet an international standard and standards from the EPA that measure the purity of this fluid. Only purchase a DEF that meets the ISO 22241 standard. Sometimes, inexpensive bottles of fluid may claim to be DEF-compatible. However, if they don’t also meet the ISO 22241 standard, they are not DEF.
Does DEF fluid go bad?
Because it doesn’t include any preservatives, DEF does come with a shelf life. The good news is, it’s a fairly long shelf life; DEF can usually be stored up to one year without any issues.
Can you use water instead of DEF fluid?
Subject: RE: Anyone replace DEF with water? Water won’t hurt the system but it will de-rate you pretty quick. ECM compares NOx values pre/post, if conversion is low it will start throwing codes and will eventually derate.
Is DEF bad for diesel engines?
While it’s good for the environment, the water and urea mixture can result in the formation of crystals that can plug up fuel filters, damage aircraft engines, and result in engine failure. DEF should never be used as an additive for any fuel, diesel or aircraft, and is sprayed directly into exhaust systems.
Can you pee in your DEF tank?
But sadly, the answer is “no”. A modern clean diesel car will recognize that your pee is not the right stuff. AdBlue solution has a far higher concentration of urea–32.5%–mixed into deionized water.
Can I drive without DEF?
Drivers need to be vigilant when it comes to DEF, so that they don’t lose time, damage their vehicles, and end up in big trouble with their employer. Ignoring the DEF light is never a good idea, so if it comes on, the driver should pull over and have their DEF refilled immediately.
Can you run a diesel without DEF?
SCR Systems Modern trucks will not run without the DEF. Hence the need for diesel truck owners to check their fluid levels frequently. Reducing emissions should be everyone’s goal. Maintaining your vehicle would also reduce emissions and DEF consumption.
Do all diesels use DEF?
A: Because almost all diesel-powered passenger cars and trucks built since 2010 are equipped with Selective Catalytic Reduction (SCR) and require Diesel Exhaust Fluid (DEF), it is readily available at most fueling stations and automotive parts retail stores. Truck stops often have a DEF pump right on the fuel island.
Why is DEF so expensive?
Prices for the diesel exhaust fluid that is a vital component of emissions systems on newer trucks are rising as costs for urea — a core DEF ingredient — have jumped. … But it’s all driven by urea prices.”
Is DEF cheaper at the pump?
Registered. Bulk def at the pump will always be cheaper.
