The Nitty-Gritty of SCR

The advancements in the green movement have improved the state of the world and have encouraged continual human advancement. For example, the development of Selective Catalytic Reduction (SCR) technology has created a major change in the transportation industry. Diesel emissions meet and even sometimes exceed EPA standards. One thing we’ve noticed, however, is that the development of new technology usually means that there is a gap in the knowledge of what exactly the technology does. That’s where this post comes in! You may have a general idea of what Victory Blue does and you can easily learn about diesel exhaust fluid, but it can be really difficult to find accurate, understandable information on SCR. Read on to discover the nitty-gritty details of SCR!

What It Is

Selective Catalytic Reduction converts dangerous NOx emissions into nitrogen and water vapor using a catalyst, the heat from the exhaust, and diesel exhaust fluid (DEF). DEF is injected into the diesel exhaust stream, and the heat from the exhaust, the fluid, and the catalyst convert the NOx into the harmless gases. The catalyst in SCR is in the DEF.

What It Needs

Since SCR systems require the catalyst to react, they require a regular top-off of DEF, the urea solution. DEF is either odorless or might have the slight smell of ammonia. Urea is not considered harmful at normal temperature, but the dust may irritate the skin, eyes and nose. The important thing to know about SCR is that it requires stringent quality control. The area around where DEF is put into the system needs to always be clean. Dust can contaminate DEF. SCR systems rely on DEF, which means that DEF needs to meet certain standards. Victory Blue DEF meets the ISO Standard 22241 (1-3) which guides the API Certification process. Victory Blue DEF is API certified. So make sure that you drive with confidence- Drive with Victory!

Benefits

Aside from helping the environment, the biggest benefits of SCR for vehicle owners are the fuel savings that the technology provides. On top of this, owners of SCR vehicles enjoy greater reliability and a longer maintenance cycle, which adds up to impressive savings over the life of the vehicle. Thus, owners of SCR vehicles are able to get more out of their vehicles than previous emission control attempts. Because SCR deals with emissions in the exhaust pipe, engineers are able to tune the engine to provide more torque and reduce fuel consumption. Due to these reasons, as well as the fact that SCR reduces dangerous emissions, SCR is the technology of choice for the majority of truck and engine manufacturers to meet 2010 emissions standards for heavy-duty trucks.

Current and Future Usage

SCR isn’t just used in eighteen-wheeler trucks. Most cars made after 2010 that run on diesel require a regular top-off of DEF because they use SCR technology. Several pick-up trucks and even many luxury passenger cars are adapting SCR in order to meet EPA requirements.
