Diesel exhaust fluid (DEF; also known as AUS 32 and sometimes marketed as AdBlue[3]) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous urea solution made with 32.5% urea and 67.5% deionized water.
This article explains how DEF (Diesel Exhaust Fluid) works in conjunction with the SCR in diesel engines and how the EPA regulations affect truck owners.
It’s called DEF for short, but the very first thing you may be wondering is what on earth is diesel exhaust fluid, and the answer is quite simple: it’s a fluid that gets injected into the exhaust system of your truck to help reduce pollution.
From the particulate filter, the exhaust gas travels past a nozzle which sprays diesel exhaust fluid into the stream of gases. DEF is made from deionized water and a very pure form of urea.
Diesel exhaust fluid, or DEF, is a key component in lowering pollutants emitted from diesel engines, helping to improve efficiency and reduce emissions.
What is Diesel Exhaust Fluid. Diesel Exhaust Fluid is a crucial component used in modern diesel engines equipped with Selective Catalytic Reduction (SCR) systems to reduce harmful nitrogen oxide (NOx) emissions. Here’s a breakdown of its properties, composition, and importance:
DEF is "Diesel Exhaust Fluid" and, as a matter of fact, modern diesels run just fine without it. DEF is instead concerned with what comes out of modern diesel engines. Diesels burn really...
Though it sounds like a close cousin of blinker fluid, DEF is an important part of regulating the emissions of modern diesel engines.
Diesel Exhaust Fluid, often abbreviated as DEF, is a non-toxic, colorless, and odorless solution composed of purified water and urea. It is injected into the exhaust stream of diesel engines equipped with Selective Catalytic Reduction (SCR) systems.
DEF is a safe, pure, and stable fluid and is regulated by the American Petroleum Institute (API). The EPA governs the production, handling, and transportation through its ISO 22241-1 standard. DEF is also known as an exhaust fluid under the brand name BlueDEF® and as an aqueous urea solution of 32% (AUS 32).
