What is Diesel Exhaust Fluid?

DEFUnless you work with big diesel trucks, the majority of drivers out there probably haven’t even heard of such a thing as diesel exhaust fluid.

Ever drive behind the big trucks on the road puffing black unpleasant smoke? This is what diesel fluid aims to eliminate.

Shipped in a 2.5 gallon jug, DEF is a non-toxic mixture of 67.5 percent purified water and 32.5 percent urea.

Peak BlueDEF is non flammable, colorless, odourless, and is safe if it comes in contact with skin. Cleanup of any spilled fluid is also easily addressed with a simple wet cloth or paper towel.

Peak has built a name for itself by researching and providing chemical products to the heavy equipment and industrial sector. With 4 decades worth of experience, Peak allows clients to get the most out of their machines while also doing the environment a favor. A great example of one of these products is the BlueDEF DEF002 Diesel Exhaust Fluid.

What Does Diesel Exhaust Fluid Do?

Companies that use heavy duty trucks that require compliance with the more strict emission laws have to modify their vehicles to allow use of this product. The diesel exhaust fluid has to be contained in its own dedicated storage tank with a system that can inject it over the catalytic converter.

Diesels are much more powerful than gasoline engines but the combustion is very dirty producing large amounts of dark particulates. So you may be wondering why we don’t directly inject this fluid into the engine to avoid the hassle of installing a separate system.

DEF is not a fuel, therefore it would adversely affect the power output of the engine.

In addition, contamination of the fluid is avoided to ensure proper functionality. During engine operation, the exhaust undergoes phase one filtration through a particulate filter. The next stage involves passing through the catalytic converter that has been dosed with the exhaust fluid.

The result is a chemical reaction that converts oxides of nitrogen to nitrogen gas and water, both of which are already present in our atmosphere. This is known as the selective catalytic reduction process or SCR for short.
