Diesel engines are typically more efficient at turning fuel into torque and power than those that burn gasoline. That gives diesel engines an advantage when it comes to keeping certain types of emissions down, with carbon dioxide output levels normally being lower per mile traveled.
Diesel is an Attractive Fuel With a Major Drawback
At the same time, the usual diesel combustion cycle also encourages the production of other compounds that can be problematic in different ways. While they do not necessarily contribute to large-scale environmental problems, nitrogen oxides emitted by diesel engines can encourage the formation of smog in particular areas.
Fortunately, this serious drawback can be minimized or even eliminated entirely. When a solution consisting of purified water and urea is injected into an appropriately designed exhaust system, the nitrogen oxides produced by a diesel vehicle can be broken down and rendered harmless.
Many types of diesel vehicles now regularly employ this approach to keep their emissions levels down. Often referred to by the abbreviation DEF, diesel exhaust fluid is a consumable supply that is the key to this productive, desirable arrangement.
A Reliable Supply of Diesel Exhaust Fluid Makes All the Difference
However, the same traits that make diesel exhaust fluid so effective in this application also mean it can be challenging to store, transport, and dispense. Impure or degraded diesel exhaust fluid will not work well at reducing the emission of nitrogen oxides, with a measurable decline in its efficaciousness resulting from even slightly suboptimal handling.
As a result, great care must always be taken to design and manage the diesel exhaust fluid supply chain. Manufacturers produce the substance in carefully controlled environments where every possible type of contamination can consistently be ruled out.
Suppliers of diesel exhaust fluid have developed their own solutions to ensure the material can be delivered to end users in perfectly pristine shape. That will often mean needing to make adjustments to conventional arrangements at every stage of the process to maintain the quality of diesel exhaust fluid through to the end. All that effort pays off, however, in the ability to leverage the benefits typical of diesel engines without the downsides.
