What is the SCR System in a Car?

SCR is a system in cars that reduces nitrogen oxide emissions. This system works in tandem with a reagent called AdBlue. It is poured inside the car's exhaust system, thereby cleaning everything that comes out of it. The process that takes place in the SCR is impossible without the AdBlue reagent, which is located in a special compartment.

The main advantage of the operation of this system is that it quite significantly reduces emissions that were previously much higher.

Also, this system can improve fuel economy because it optimizes engine performance. The only negative side is the presence of AdBlue, because if it runs out, then the process cannot be started properly. To constantly monitor the level of emissions and process them, you need to keep your eye on the device and pay attention to any malfunctions that can occur.

Do SCR Systems & Catalytic Converters Work Together?

If a person wants to put a catalytic catalyst and an SCR system in his car at the same time, he most likely will not encounter any issues. However, the process is obviously cannot be done on your own, unless you have specific knowledge and necessary tools. The operating principle of SCR and general catalysts differs a bit, but they were made for the same purpose, which is the reduction of harmful emissions.

Most of the time, a catalytic converter is installed in cars that use gasoline as fuel. Thus, it is crucial to understand, that SCR cannot be installed on such vehicles. Keep in mind, that SCR works with diesel engines and often supported by DPF (Diesel Particular Filter) system.

However, the catalytic converter and the SCR system can work and clean up harmful emissions if installed on the correct diesel vehicle. By combining these two parts together, it will help to increase the efficiency of processing the exhausts for which they are intended.

And all the after-treatment tasks will be very conveniently distributed because the SCR system is further away from the catalyst, which means that it will process everything left after the catalyst before processing.

Installing an additional device that will help clean other exhausts can look like a good thing from first glance, however, it has to be done with caution and knowledge to specific details and components of the vehicle.

The Future of SCR Systems in Diesel Emission Control

The future in the world of catalysts and SCRs is great because these parts are environmentally friendly and emission efficient. In the future, the SCR system will undoubtedly improve in terms of the efficiency of cleaning up emissions of nitrogen oxides. This will be possible because the catalysts will become more powerful and will help the SCR system work together combined.

The development of new regents and components is also quite essential, scientists are thinking about improving AdBlue, which already shows good results nonetheless. Thanks to new catalysts and an improved reagent, one can only imagine how greener cars can become in the future.

Besides, with the development of the requirements and environmental standards of countries around the world, these innovations will not make people wait long for them, because reducing emissions is what everyone wants to achieve.

Summing up, we can say that the future will be as it should be, the SCR system paired with catalysts will become many times better and will work for the benefit of mankind.
