Agricultural Machinery Export

If you are exporting Agricultural machinery to any country where there are no emissions laws, you will need to delete all emissions systems from the machine before it leaves the UK. The diesel available in these parts of the world is lower quality in comparison to the fuel available across the UK, although the machines are capable of running on the lower quality fuel the emissions systems can’t cope with it. DPFs will block quickly requiring repeat regens until they become overwhelmed, EGR’s will circulate heavily sooted exhaust gas blocking inlets and increasing carbon deposits throughout, causing many issues including Variable geometry turbo problems, AdBlue systems will struggle to keep up with the reduction of NOx gasses assuming that AdBlue is available at the destination of the machine, often resulting in failures where parts are not available.

These deletes can be carried out easily in preparation to export. If you have diagnostic equipment, in most cases the ECU’s can be sent to Agri Remaps or alternatively the work can be carried out on the machine on-site.

Removing these emissions systems from any machine only improves the reliability and efficiency. Removing the DPF means no more regens, The DPF is a filter in the exhaust, it has no effect on the engines running unless it becomes blocked. This filter collects soot and then burns it off when conditions are right often increasing fuel use to increase exhaust temperature helping to burn off the stored soot. Alternatively, the machine will ask for a standstill regen, at this point the machine is just burning fuel to burn off soot to keep the exhaust filter clear. Both types of regen also produce ash, the ash is permanently stored in the DPF and can only be removed by either removing and cleaning it or replacing it, meaning the heavier the soot the shorter the DPF life.  The DPF delete allows the exhaust filter to be removed leaving the machine to function as if it never had one; All DPF error codes are removed from the software, regens are no longer required and fuel usage is reduced. It’s also worth noting that Mass air flow and injector faults increase the soot produced, dramatically shortening the time between regens and shortening the time it takes for ash to build up.

EGR valves recirculate exhaust gases back through the intake system. These exhaust gases are heavy with carbon and steadily coat everything they pass through with carbon, this slowly reduces efficiency and is known to have cause common failures on many engines. Common failures include:

-EGR valve failure, where the valve sticks open or closed altering the gas flow expected by the machine causing derate, often if it sticks open that itself causes reduced boost and a reduction in power.

-EGR component failure, this can appear in a multitude of different ways. Some engines suffer EGR cooler failure where the engines coolant is introduced into the intake or exhaust gas is pushed in to the cooling system others have issues with coatings from inside the valve and its pipework flaking off causing serious damage to the block liners resulting in catastrophic engine failure, and all are plagued by carbon build up throughout the EGR system, Intake, Turbo and combustion chambers, which more often than not results in component failure, engine damage or reduced performance.

An EGR delete removes all EGR fault codes and operation from the machine’s software, it prevents derates and ensures the EGR stays shut removing the circulation of exhaust gases and preventing future failures. In the event of an already failed EGR that is stuck open a blank can be fitted, this solution also allows the removal of the EGR cooler or in most cases the entire EGR system if required.

AdBlue systems have no physical bearing on the engines running. AdBlue is injected into a part of the exhaust downstream after all the important power making is done. The process is a gas reaction that reduces NOx gas. If the AdBlue isn’t working the only difference in the whole process is that NOx gas emissions from the exhaust are increased, the engines workings are completely unchanged, or at least they would be if it wasn’t for sensors and software. The AdBlue system is constantly monitored for correct operation and faults. If there are any discrepancies at all the system decides on how serious it thinks it is and either provides a warning, a countdown, or puts the machine in derate or limp mode, often even after repair this still need resetting with manufacturer or aftermarket software. These warnings or derates are not to protect the engine but to ensure you get the fault fixed, the engine will operate for its entire life without a single injection of AdBlue in the exhaust and if it wasn’t for the software and sensors, it would do exactly that.

An AdBlue delete stops the use of AdBlue and removes all the fault codes stopping derates allowing the engine to operate issue free. The AdBlue pump or injector can be electronically disconnected and, in most cases, removed from the machine if required. In some cases the Tank level has to be kept working but often this can be worked around.

All Deletes allow the machines to work exactly as they have previously without fault codes, errors or lights on the dash. Emissions related derates and limp modes are removed allowing the machines to run on lower quality fuel problem free around the world.
