Diesel Exhaust Fluid: Keeping Diesel Engines Going Strong

During the late 1800s, certain aspects of the world changed a great deal. Gasoline engines made their first appearances, and a few years later, diesel motors entered the mix. Though gas burners were the first to be introduced, diesel counterparts quickly rose to fame. In many instances, they’re the most effective and efficient options on the market. While they certainly have their places in automotives and heavy machinery, the do give off their fair shares of harmful emissions.

Finding a Solution

In the beginning, emissions weren’t really considered an issue. Over the years, though, society and the powers that be became a great deal more conscious of the carbon footprints each generation was leaving behind. Regulations were put into effect to help create balance, and experts were charged with the task of finding ways to counteract the problem of pollution. For diesel engines, diesel exhaust fluid became the solution.

How Does DEF Counteract Diesel Pollution?

DEF is a chemical additive designed to eliminate many of the harmful byproducts of the diesel combustion process. When these types of engines burn fuel, they give off potentially dangerous nitrous oxide. This gas can have detrimental effects on the human body as well as the environment in high concentrations. DEF serves to neutralize these emissions. It’s comprised of deionized water and urea, components known to transform nitrous oxide into simple, innocuous water and nitrogen.

How to Use DEF Effectively

In vehicles and machinery designed to use DEF, this compound is added to a tank separate from that in which fuel is stored. When diesel engines are in use, DEF is filtered into their exhaust system via an automated device. There, it works its magic to neutralize the dangerous chemical byproducts of combustion.

The device responsible for its distribution adds small amounts into the exhaust based on engine capacity, running temperature and certain other factors. When DEF levels begin to run low, the device lets operators know it’s time for a refill via a warning light much like those for low fuel, engine oil and coolant levels.

Diesel engines have helped transform the world in a number of ways. They’re among the most powerful and cost-effective options for a wide range of equipment and heavy machinery. Without DEF, those relying on diesel might’ve had been forced to find other alternatives. Thanks to this well-known additive, though, diesel engines are still going strong while remaining in compliance with environmental regulations.
