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 .
Diesel exhaust is the exhaust gas produced by a diesel engine, plus any contained particulates. Its composition may vary with the fuel type, rate of consumption or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator ...
The Cummins ISX diesel engine can be run in a dual fuel configuration, meaning it can properly operate on diesel fuel and natural gas. The burning of a natural gas alternative preserves diesel thermal efficiencies. The more efficient engine can produce less emissions in turn. The ISX can achieve this by altering ignition delay and injection timing.

Diesel fuel has many colloquial names; most commonly, it is simply referred to as diesel.In the United Kingdom, diesel fuel for road use is commonly called diesel or sometimes white diesel if required to differentiate it from a reduced-tax agricultural-only product containing an identifying coloured dye known as red diesel.
An ingredient in diesel exhaust fluid (DEF), which is 32.5% urea and 67.5% de-ionized water. DEF is sprayed into the exhaust stream of diesel vehicles to break down dangerous NO x emissions into harmless nitrogen and water. A component of animal feed, providing a relatively cheap source of nitrogen to promote growth
BlueTEC is Mercedes-Benz Group's marketing name for engines equipped with advanced NO x reducing technology for vehicle emissions control in diesel-powered vehicles.The technology in BlueTec vehicles includes a selective catalytic reduction (SCR) system that uses diesel exhaust fluid, and a system of NOx adsorbers the automaker calls DeNO x, which uses an oxidizing catalytic converter and ...
To meet EPA Tier 4 emission standards for nitrogen oxides , manufacturers rely on one of two methods: exhaust gas recirculation (EGR), where exhaust gases are cooled and recirculated back through the combustion cycle, or selective catalytic reduction (SCR) using urea-based diesel exhaust fluid, which converts NOx in the catalytic converter to ...
