What is diesel exhaust fuel used for?

What is diesel exhaust fuel used for?

What is the Purpose of Diesel Exhaust Fluid? In 2010, the EPA required diesel engines to reduce their production of (NOx) nitrogen oxides. That reduction is accomplished with the additive Diesel Exhaust Fluid (DEF). This fluid reduces NOx and air pollution.

Is diesel exhaust fluid fuel?

DEF is not a fuel additive and never comes into contact with diesel. It is stored in a separate tank, typically with a blue filler cap.

Is diesel exhaust fluid the same as diesel?

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.

What happens if I run out of DEF?

The Cost of Running Out of DEF‍ In a best-case scenario, running out of DEF simply means refilling the tank and restarting your machine. If you have DEF nearby, you could be back to work within minutes. But sometimes it isn’t so quick and easy.

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.

How do you buy DEF?

Def can be purchased with a company fuel card, credit card or cash at most truck stops and retail gas stations. At cardlock fuel stations you will need a cardlock fuel card that is accepted at that specific location.

Is diesel exhaust worse than gas?

The simple answer is diesel emits slightly more pollutants per gallon than gasoline does. But, as is often the case, the simplest answer does not tell the whole story with respect to diesel emissions versus gasoline. The reality is, gasoline both emits more emissions and is a greater polluter than diesel.

Is diesel exhaust harmful to humans?

Workers exposed to diesel exhaust face the risk of health effects ranging from irritation of the eyes and nose, headaches and nausea, to respiratory disease and lung cancer.

Can you use water as DEF fluid?

If you put water in an EMPTY DEF tank, there will be no urea injected into the exhaust to convert to ammonia. Ammonia is an essential requirement to eliminate NOX (Oxides of Nitrogen) via the SCR (Selective Catalytic Reducer).

How many miles will 1 gallon of DEF last?

between 300 to 500 miles
Most DEF tanks require one gallon of DEF for every 50 gallons of diesel fuel, and one gallon will generally last between 300 to 500 miles.

Can you run a diesel without DEF?

If you ignore the DEF warning the truck will cease to work. Some diesel engine manufacturers allow the engine to go into reduced power mode so the truck can “limp home” or limit the number of times you can turn the engine over. At some point though the diesel engine will not start.

How much does DEF 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.

Is diesel exhaust cleaner than gas?

Diesel engines are cleaner than gasoline engines and alternative fuel engines as well. Diesel engines do not produce as much carbon dioxide as gasoline. They may produce more carbon dioxide than alternative fuels.
