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.
3 Οκτ 2024 · Diesel exhaust fluid, or DEF, is a key component in lowering pollutants emitted from diesel engines, helping to improve efficiency and reduce emissions.
To comply with cutting down emission levels, diesel engine manufacturers as a whole decided to implement a selective catalytic reduction (SCR) system, which includes an SCR catalyst, a pump, a tank, lines, an injector, and a synthetic, non-toxic diesel exhaust fluid (DEF).
9 Σεπ 2023 · 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:
5 ημέρες πριν · Diesel Exhaust Fluid, commonly known as DEF, is a non-toxic solution made from a mix of urea and deionized water. It’s designed to reduce the harmful emissions produced by diesel engines. DEF is stored in a separate tank on your vehicle and is injected into the exhaust stream to break down harmful nitrogen oxide (NOx) emissions into harmless ...
20 Μαρ 2023 · Diesel exhaust fluid is a clear liquid you can buy at gas stations, supermarkets, auto parts stores, or even big box home improvement stores, and it usually comes in 1-gallon jugs or 2.5-gallon cardboard boxes with a plastic liner inside.
24 Απρ 2024 · Diesel Exhaust Fluid (DEF) is formulated from 32.5% urea and 67.5% deionized water. DEF reduces the emissions of nitrogen oxides (NOx), which are harmful pollutants produced during the combustion of diesel fuel. The process begins when DEF is injected into the exhaust stream of a diesel engine.
