Diesel exhaust fluid definition

Diesel exhaust fluid or “DEF” means a liquid reducing agent used in conjunction with selective catalytic reduction to reduce NOx emissions. DEF is generally understood to be an aqueous solution of urea conforming to the specification of ISO 22241.

Diesel exhaust fluid means an aqueous urea solution

Diesel exhaust fluid means a preparation of aqueous urea [(NH2)2CO], containing 32.5 per cent by mass of technically-pure urea in high-purity water.

Examples of Diesel exhaust fluid in a sentence

• Diesel exhaust fluid (also referred to as DEF or AUS 32) is injected into the diesel exhaust stream and the heat from the exhaust, the fluid, and a catalyst convert the NOx into the harmless gases.Diesel exhaust fluid is a 32.5% solution of technically pure urea in purified water.

• Examples of such abnormal conditions may include excessive exhaust backpressure from an overloaded particulate trap, and running out of diesel exhaust fluid for engines that rely on urea-based selective catalytic reduction.* * * * *Diesel exhaust fluid (DEF) means a liquid compound used in conjunction with selective catalytic reduction to reduce NOX emissions.

• The consumer is regarded as the driving force in the market with the power of transformation (ibid.).

• The project also has a self-targeting mechanism in its design, allowing communities to decide whether they are willing to make the commitment to participate.

• Section 1039.801 is amended by revising the definitions for ‘‘Diesel exhaust fluid (DEF)’’ and ‘‘Emergency equipment’’ to read as follows:§ 1039.801 What definitions apply to this part?* * * * *Diesel exhaust fluid (DEF) means a liquid reducing agent (other than the engine fuel) used in conjunction with selective catalytic reduction to reduce NOX emissions.

• Since 2010, Selective Catalytic Reduction (SCR) has been incorporated into vehicle designs by many diesel vehicle manufacturers to meet the 2010 standards in new diesel trucks, vans and SUVs. Diesel exhaust fluid (DEF) is used with the SCR system to achieve emissions requirements.

• For some meters, you may accomplish this by using a suffi- cient length of straight tubing (such as a length equal to at least 10 pipe diam- eters) or by using specially designed tubing bends, orifice plates or straight- ening fins to establish a predictable ve- locity profile upstream of the meter.§ 1065.247 Diesel exhaust fluid flow rate.(a) Application.

More Definitions of Diesel exhaust fluid

Diesel exhaust fluid or “DEF” means an aqueous urea solution used in selective catalytic reduction to lower oxides of nitrogen concentration in the exhaust emissions of diesel engines that meets the last version of International Organization for Standardization (ISO) specification for DEF.

Diesel exhaust fluid or “DEF” means a liquid reducing agent (other than engine fuel) used in conjunction with selective catalytic reduction to reduce NOX emissions. DEF is generally understood to be an aqueous solution of urea conforming to the specification of ISO 22241. DEF is used in Generation 2 and Generation 3 vehicles and is sometimes referred to by the trademarked name, “AdBlue.”
