Diesel exhaust fluid is a new approach to global emissions reduction. Learn more about DEF and what it does for your diesel engine.
Diesel Exhaust Fluid (DEF) is the reactant necessary for the Selective Catalyst Reduction System (SCR system) function. DEF is required for the proper after-treatment operation of your emissions system. It is a carefully blended aqueous urea solution of 30% high-purity urea and 70% deionized w...
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...

The article presents information on a study conducted by Southwest Research Institute and Shell on diesel. The study found that major constituents of light-duty diesel exhaust can be organized into a synthetic diesel exhaust, useful for exhaust emissions after treatment development. The study also ...
High idle reduces soot in the exhaust which results from incomplete combustion at low engine revs. This is important because when diesel engines are operating at low RPMs, more soot is generated. That can fill up the diesel particulate filter (DPF) which has been installed on diesel engines si...
The engine in the hybrid car is powerful enough to move the car along on the freeway, but when it needs to get the car moving in a hurry, or go up a steep hill, it needs help. That "help" comes from the electric motor and battery — and this system steps in to provide the nec...
Turbos utilize exhaust gases to power a turbine wheel, which is connected via a shaft to a compressor wheel. As the two wheels turn, large amounts of ambient air are sucked in and compressed. This air is passed through a charge-air cooler to further increase its density before it en...
Diesel engine, like other internal combustion engines, converts chemical energy contained in the fuel into mechanical power. Diesel fuel is a mixture of hydrocarbons which—during an ideal combustion process—would produce only carbon dioxide (CO2) and water vapor (H2O). Indeed, diesel exhaust ...
Believe it or not, lightly glowing manifolds are not that uncommon on diesels, particularly if they've been straining under a load. Even on its best day, the average diesel's exhaust gas temperatures can push its manifold to glow a dull red in low-light
