What Is Diesel Exhaust Fluid Used For? DEF is used to break down NOx gases produced during diesel combustion. The liquid reduces harmful nitrogen oxide emissions. Theseemissions contribute to air pollution, smog
DEF, short for diesel exhaust fluid, is a component in diesel engines to reduce harmful emissions and improve environmental sustainability. Diesel exhaust fluid is made from a formulated mixture of urea and deionized water and is injected into the exhaust stream of diesel vehicles that have Selectiv...
Click here to read about after-treatment of diesel exhaust fluid (DEF) also known as AdBlue. We take a look at what diesel exhaust fluid is and why it’s needed.
All told, diesel exhaust fluid is just as important to your vehicle as fuel, coolant, oil and all the other fluids you regularly check and replace. Your machine will not function without DEF, and you can face serious consequences from letting the DEF tank run dry. Learn moreabout T3's re...

AdBlue is a diesel exhaust fluid, not a fuel additive. It's stored in a separate tank and is topped up via a (usually) blue filler cap located either next to your fuel filler, in the boot or under the bonnet. It’s extremely important that AdBlue is never added to the fuel tank ...
DEF is an acronym for Diesel Exhaust Fluid. Its purpose is to reduce harmful tailpipe emissions that are produced by a running diesel engine. Without DEF, diesel exhaust gases can be very harmful to the environment. DEF is technically a combination of urea and deionized water. ...
A turbocharger is a critical component highly customized for the engine. It uses an engine’s exhaust gas to drive the turbine wheel up to 350,000 RPM. The turbine wheel then drives the compressor wheel through a shaft. The compressor wheel provides compressed air to the engine, and th...
Nachtman says the only scheduled maintenance for Navistar’s SCR system (Cummins Single-Module aftertreatment) is changing the diesel exhaust fluid tank neck filter, which is in place to keep grit and debris out of the tank. “It’s a scheduled item at 30,000 miles,” he says. “That’...
