How the emulator is improving the engine’s work?

The device works as a digital replacement for specific parts of the emission control system, including:

– Diesel Particulate Filter (DPF)

– AdBlue Pump

– Temperature Sensors

– Nitrogen Oxide (NOx) sensors

– Differential Pressure Sensor

– Fluid Level Sensor

– Fluid Quality Sensor

– Tank Pressure Sensor

– NH3 (Ammonia) Sensor

– Fluid Level Sensor

– Fluid Quality Sensor

By replacing the signals from the sensors, the device can cause the error codes to disappear. This is because the emulator mimics the sensor signals that the ECU expects to receive when the system is functioning correctly. As a result, the ECU perceives that everything is working as it should, and thus, no error codes are generated. This is one of the key benefits of using an emulator in a vehicle system.

The leader in fuel maintenance and management solutions, AXI international wrote dangers that come with the DPF filter that isn’t maintained as the producers recommend.

Installation of the DPF/DEF emulator

The DPF emulator & DEF emulator is a key innovation in modern diesel vehicles. Our solution replaces all components of the emission control system, thereby restoring lost engine power. As a digital replacement, the DPF/DEF emulator mimics the functions of key parts such as the diesel particulate filter (DPF), DEF (AdBlue) pump and various sensors.

The device ensures efficient vehicle operation, bypassing the limitations of traditional systems. Essentially, the DPF/DEF emulator is an effective way to avoid immobilizing failures.

DPF Check Engine Light

Among the many emulation devices, two types of devices can be distinguished. With the first type of DPF/DEF emulator, the idea is to establish connections to independent sensors, such as temperature sensors, differential pressure sensors and NOx sensors.

The DPF/DEF emulator is designed to understand the values it receives and sends to the ECU (engine control unit), signals that mimic those of the sensors, to trick the system into believing that the two systems are operational. This is accomplished by reading data from the sensors and then sending the appropriate signals to the ECU with proper conversion using the device’s program.

The second type of devices, thanks to the design of the ACM (Aftertreatment Control Module), makes it possible to put the entire device on a single circuit board. The installation process is simpler here. Like the first type, this DPF/DEF emulator also sends specific values to the ECU to trick the system into thinking that both systems are working.

It is always advisable to read the manufacturer’s instructions or, if necessary, seek the support of a professional.

The benefits of the DPF/DEF emulator

The benefits of installing our solution are numerous. Firstly, it eliminates emission-related error codes entirely, saving time and effort spent on troubleshooting and repairs. Additionally, it eliminates the need for regular maintenance of the emission system, saving both time and money. By restoring full engine power and eliminating the need for DPF filter regenerations, it enhances operational efficiency while reducing fuel consumption.

Financial savings accrue from reduced expenses on emission system repairs and maintenance, as well as from the elimination of Diesel Exhaust Fluid (AdBlue) costs. Moreover, by minimizing emission-related downtime, the device maximizes machine effectiveness, ensuring continuous operation without idle-mode interruptions. Robust, shock-resistant components ensure reliability even under extreme conditions, backed by our comprehensive post-purchase support and tech assistance.

Considering these significant advantages, the DPF/DEF emulator clearly emerges as an indispensable tool that plays a crucial role in optimizing the performance and efficiency of diesel vehicles, thereby enhancing their overall functionality.


To summarize. Exhaust aftertreatment system emulation devices open the way for users of modern diesel engines to a simpler and much more fail-safe diesel engine. The possible savings from eliminating the constant fuel-intensive regeneration and cleaning of the DPF will allow you to do keep your focus on what’s important.
