During the last few years, diesel has faced a rough time, but progressively ordinary technology is working to modify the fuel’s reputation and make diesel vehicles feasible for the future.
Back in 2010 Long haul truckers, diesel truck enthusiasts and fleet managers conjointly had a Chicken Little movement. During this movement, the Environmental Protection Agency made the use of particular catalytic reduction(SCR) mandatory in diesel engines.
Why? Due to the things that happen to brighten the magic of SCR is a consumable fluid known as diesel exhaust fluid. With the introduction of this fluid, all diesel vehicle owners have to make DEF a part of their vehicles.
It’s a fact that nobody desires to spend more without getting anything fruitful in return. But by involving DEF and SCR they have received the appropriate return and that is extremely fuel-efficient and diminished emission. This made the hassle of filling the fuel every now and then reduced, thus it is worth it.
So now you know what DEF and SCR are, but why they are popular is another question that needs to be explained.
Firstly, SCR (selective catalyst reduction) is not a novel technology; in fact, the EPA made it mandatory in the last decade. So that makes the technology available for nearly half a century and was firstly utilized by the power generation industry to diminish oxides of nitrogen from power plants that run with coal-fire.
In a vehicle that is SCR-equipped, the exhausted gas from the engine is defeated foremostly with the help of a specific filter to capture every soot and ash created from burning what is a comparatively impure fuel.
The exhaust gas travels from the specific filter past a nozzle that sprays def diesel exhaust fluid into the gases of streams. DEF is created from deionized water and an extremely pure form of urea. This is a cultivated form of the compound and is primarily used in the agricultural industry as an element of fertilizer.
Now comes the question of how SCR works? Well, the diesel exhaust fluid and hot exhausted gas enter the catalytic converter where the reaction between DEF and the exhaust gas takes place with a diversity of metallic elements to turn nitrogen dioxide and monoxide into water and nitrogen. This is the extremely easiest version of SCR works but it’s not how your car’s catalytic converters work that are gasoline-powered. Mostly the use of SCR in modern diesel engines works in amalgamation with exhaust gas recirculation to diminish emissions.
Gaining knowledge about the increase in the visible emission control system and becoming more critical, many manufacturers started to offer diesel models more in traditional segments of gasoline-dominant.
Every big company in the automobile industry is either planning or offering to give minor-displacement lighter-duty diesel engines in their huge-volume truck range. For example, Ford’s have V6 PowerStroke and Ram 3.0-liter EcoDiesel V6, all these engines will have DEF tanks and SCR systems.
When the big diesel engines come into existence def diesel exhaust fluid becomes critical because these vehicles go miles and massive amounts of fuel are required. Thus now at truck stops, you will get DEF sold at pumps.
The bottom line is when you use DEF, you are reducing the emission from the environment and helping human life as well as the plant being a much safer place.
