Removing Adblue from Deutz Fahr - Deutz Engines

Agro tuning pro

Deutz engines

Deutz Fahr specializes in agricultural machinery, with their recent models meeting stringent pollution standards, primarily powered by Deutz engines. These engines, such as the TCD series, comply with Tier 4F/Stage 5 standards. They are controlled by an Electronic Engine Control Unit (EMR), with the latest iterations being EMR4, which monitors feedback and errors related to the exhaust gas after-treatment system. Most of these engines are equipped with an Exhaust Gas Recirculation (EGR) valve, a Particulate Filter (FAP/DPF), and Adblue (Selective Catalytic Reduction - SCR system).

Deutz Fahr Emission Control System: SCR System

Neutralizing the aftertreatment system, which involves removing the Adblue from Deutz Fahr vehicles, begins with disabling the Adblue operation. This entails halting the consumption of Diesel Exhaust Fluid (DEF) and disconnecting various components such as the pump, NOx sensors, and Adblue injector.

  • Zero consumption of Adblue (DEF)
  • Elimination of the Adblue warning light on the dashboard
  • Deactivation of limp mode, which reduces torque
  • Possibility to disconnect Deutz Fahr Adblue system components.

Neutralizing the DPF in Deutz Fahr Emission Control System

Deutz engines are equipped with particle filters designed to trap micro-particles. Positioned just after the catalytic converter, the particle filter gradually accumulates soot emitted by the engine. As it fills up, it can hinder engine performance, necessitating a regeneration process to burn off the accumulated soot. However, if the soot level exceeds a certain threshold, regeneration becomes impossible, triggering degraded mode and restricting the tractor or machine’s performance.

Our solution offers:

  • Elimination of particulate filter regeneration
  • Permanent erasure of dashboard faults
  • Removal of audible alerts
  • Option to empty the particulate filter, preventing further soot accumulation
  • Deactivation of limp mode, preventing engine torque reduction during degraded mode.

This option can be added to the SCR system according to your requirements, offering a cost-effective alternative to replacing the entire exhaust system.

Deutz Fahr Emission Control System: EGR Valve

The EGR valve recirculates exhaust gases back into the intake system for a second combustion cycle. While intended to reduce air pollution, it can actually contribute to engine contamination. This counterintuitive process reintroduces unburnt particles into the intake, contrary to the optimal condition where the air should contain maximum oxygen molecules for peak performance. Neutralizing this valve prevents the intake ducts of your Deutz engine and Deutz Fahr machine from clogging. Physically disconnecting the valve and sealing it with a metal plate blocks gas passage.

Benefits of this approach include:

  • Optimal engine operation
  • Possibility of EGR valve blockage
  • Feasibility of physical disconnection
  • Neutralization of faults related to EGR valve issues in the EMR4 engine ECU
  • No engine torque restriction caused by EGR valve faults.

Deutz Fahr: Assistance and Viability of AdBlue Elimination and Aftertreatment System Modification

Applicable to:

  • All Deutz engines
  • All vehicles equipped with FAP, EGR valve, and SCR (AdBlue)
  • All Bosch EDC17 and MD1 type EMR4 ECUs
  • All TCD engines meeting Tier 4F/Stage V standards.

Emulating Systems via EMR4 Programming

The removal of the anti-pollution device from Deutz Fahr machinery is conducted directly within the EMR engine management unit. Prior to any modifications, the EMR memory is backed up as a precautionary measure. We establish connection either through the manufacturer’s diagnostic socket or directly to the engine ECU pinout via bench method, without physically opening the unit. The programmed operational data enables:

  • Neutralization of the entire emission control system
  • Prevention of degradation and loss of power/torque
  • Enhancement of engine performance, including improved torque and power management
  • Emulation of operational data through reverse methods (e.g., resetting DPF soot levels to zero).

Deutz Fahr Adblue withdrawal: Mercedes engines

Mercedes engines

Similar to Deutz engines, Mercedes engines powering the largest machines in the range can encounter issues with Adblue. It's also feasible to disable the anti-pollution system in these vehicles. This includes deactivating SCR, DPF, and EGR valve functionalities.

Mercedes Engines and Feasibility

Mercedes engines differ in operation from Deutz engines. Exhaust after-treatment is managed by two interconnected modules, the MCM (Motor Control Module) and the ACM (After Treatment Control Module), which communicate via the CAN BUS network. Modification of data in both ECUs is necessary due to this interconnectivity.

For MCM and ACM HDEP (2.1) models up to 2019/2020, the Bench method is directly applicable for machines up to 2018/2019 with D4 hardware. For machines up to 2020, unlocking program read/write operations by opening the MCM box is necessary beforehand.

Key points:

  • SCR, DPF, and EGR deactivation is feasible.
  • For machines from 2021 onwards, reprogramming the MCM box is possible after unlocking read/write operations. However, data modification in the new-generation ACM (ACM3 model) is currently unavailable. Efforts are underway to develop solutions for reading and writing programming data in these new ECUs.
