For Isuzu 4JJ1, 4HK1, 6HK1, 6UZ1, and 6WG1 Industrial Engines

The EMRT Professional SCR & DPF Emulator is a heavy-duty, complete-system emulation solution for Isuzu Stage V engines. Designed for clean integration into civil and earthmoving machinery, this unit provides a total bypass of both the SCR (AdBlue) and DPF/DPD (soot filter) networks, permanently preventing costly downtime, forced regenerations, emission fault codes, and engine derates.

Key Features

• Full Dual Emulation – Replaces the entire SCR/AdBlue and DPF/DPD system electronic signals, ensuring the machine operates at 100% power without derates, filter blockages, or warning lights.

• Simple Integration – Clean, efficient installation layout designed for straightforward workshop or field technician setup.

• Ruggedised Protection – 100% waterproof housing built with premium, industrial-grade components to survive the extreme vibrations, dust, and harsh operating conditions of Australian worksites.

• Performance Security – Completely eliminates AdBlue-related fault codes, DPF differential pressure errors, and prevents the engine from entering limp mode.

•  

Emulated System Components

The emulator completely overrides and outputs precise simulated data streams to the Engine ECM for the following components:

• DCU Control Unit

• NOx Sensors (Upstream & Downstream)

• Urea Dosing Pump Module

• Urea Quality and Level Sensors

• DPF / DPD Differential Pressure Sensors

• Exhaust Gas Temperature (EGT) Sensors

Isuzu Stage V Engines:

• 4JJ1 Stage V

• 4HK1 Stage V

• 6HK1 Stage V

• 6UZ1 Stage V

• 6WG1 Stage V

Application Note

Full Exhaust Integration: This emulator is developed specifically for Isuzu Stage V engines equipped with both an SCR system and a diesel particulate filter (DPF/DPD). It fully emulates both exhaust aftertreatment systems simultaneously. For optimal engine performance and to prevent exhaust back-pressure, it is recommended to ensure the physical DPF/DPD core is unobstructed.
