Have you heard about the Selective Catalytic Reduction system? Here are some facts you probably didn’t know about the SCR systems, AdBlue and AdBlue emulators.

  1. “SCR” stands for the Selective Catalytic Reduction system
    Selective Catalytic Reduction is a technology that reduces air pollutants by converting toxic nitrogen oxides into nontoxic diatomic nitrogen and water. It is widely used commercially. 
  2. The SCR system has been in use since 1957
    Selective Catalytic Reduction was patented in 1957 in the United States. In recent years the system has become the most common way to reduce the level of air pollutants emitted by diesel engines.
  3. SCR systems are commonly used in European Union and the U.S.
    Following the U.S. Environmental Protection Agency emission regulations and the European Union directive from 2014 called Euro 6, diesel engines are required to meet nitrogen oxides standards. The way to meet both indicated standards are Selective Catalytic Reduction systems with the AdBlue fluid. 
  4. AdBlue is made of urea
    The SCR system uses a diesel exhaust fluid (DEF) also known as AdBlue, which is made of aqueous urea solution which is 32,5% urea and 67,5% water.
  5. AdBlue fluid freezes below -10°C
    Diesel exhaust fluid freezes below -10°C (14°F) and when it happens, it causes diagnostic system errors that lead to power loss. Generally speaking, the SCR system is a great idea. It helps protect the environment and does not affect the engine performance. Unfortunately, the Selective Catalytic Reduction system and its components perform a high failure rate, which means huge costs for the drivers. That is why SCR emulators such as adblue emulator euro 6 scania and adblue emulator euro 6 renault are growing in popularity.

    An SCR emulator (or an AdBlue emulator) is a device that simulates a functioning SCR system. It sends the same signals to the engine control as the SCR system. It can be deactivated or dismantled anytime and does not interfere with the truck’s electronics. Euro 6 and EPA regulations state the law for the U.S and European countries. If you are driving outside their borders you are probably not required to use the SCR system and in some countries (especially in cooler climate) you probably better not. If you are searching for adblue emulator euro 6 renault or adblue emulator euro 6 scania, check BlueTruck24BlueTruck24 offers a wide range of high-quality SCR emulators compatible with any truck. They are easy to install and uninstall and come with a 2-year warranty.
