SCR emulator, also known as Adblue emulator, is a device designed to regulate SCR (Selective Catalytic Reduction) setup. SCR emulators are used to replace SCR systems and make them discrete without harming any other vehicle parts. SCR Emulators are an excellent way to override SCR setups without any loss of torque or power in the engine.

Working if SCR Emulators

SCR emulators are developed to override the current running SCR systems. SCR emulators are categorized on various parameters, and the most common category is the type of engine or truck model the emulator is installed in.

Principle of working: An SCR emulator works by sending specific signals to the engine control setting of a vehicle. The engine receives this signal and proceeds to shut down the SCR system of the vehicle while ensuring smooth engine performance simultaneously.

So here is a brief illustration of how an SCR emulator works:

  • An SCR emulator is installed within a compatible vehicle.
  • The emulator then takes control over the Selective Catalytic Reduction or SCR of the vehicle and its components.
  • SCR emulator is designed to imitate the exact functioning of the SCR at the OBD level.
  • When the SCR emulator is installed, it thrusts the vehicle’s SCR system onto dormant mode and transits necessary information to the central ECU simultaneously to avert the vehicle from going into the limp mode.
  • This ensures that there are no fallacies in the vehicle’s OBD setup because the SCR emulator takes control over everything.
  • This way, the SCR emulators can let you drive around safely even with faulty SCR systems.

Benefits of an SCR emulator

SCR emulator is a wonderful way to avoid hefty repair costs and risky vehicle breakdowns. Here are some other benefits that it extends:

  • SCR emulator emulates signals and data to the main ECU, which ensures an error-free OBD system.
  • There is no loss of engine power, or DTC, or any smoke exhaustion from the exhaust system.
  • It does not consume DEF (Diesel Exhaust Fluid), which reduces diesel cost significantly.
  • It restores fuel consumption levels and engine power levels to regular figures.
  • Any kind of diagnostic error related to SCR system failure can be prevented by installing an SCR emulator.

Tires of SCR Emulators

SCR emulators were first introduced to prevent bothersome SCR system failures of a vehicle. On the basis of generations, the division can be as follows:

  • First-generation SCR emulators: The first-generation SCR emulators were designed to avert errors that damage the OBD setup of a vehicle in case of SCR failure.
  • Second generation SCR emulators: The second generation SCR emulators were designed to override the actual SCR system in case of a faulty SCR setup.

On the basis of engine types, SCR emulators can be of two types:

  • EURO 5 diesel engine
  • EURO 6 diesel engine

Both of these emulators are not compatible with one another and cannot be used interchangeably.

Applications of SCR emulator

SCR emulators can be applied to many areas like:

  • Heavy trucks
  • Buses
  • Agricultural machinery
  • MAN
  • DAF
  • Renault
  • Ford
  • Mercedes-Benz
  • Iveco
  • Volvo
