AdBlue agricultural machines

What is AdBlue fluid?

AdBlue fluid is the commercial name of a solution of urea in water, widely used in exhaust emission reduction systems (SCR) in diesel engines, especially in agricultural machinery. This special fluid is used to reduce nitrogen oxide (NOx) emissions by neutralizing these substances in the exhaust system.

AdBlue is essential in many modern agricultural machines that are equipped with advanced emission control systems. The NOx reduction process takes place in the SCR catalytic converter reactor, where AdBlue liquid is injected into the exhaust stream. This process produces ammonia, which then reacts with nitrogen oxides, converting them into harmless nitrogen and water.

The key issue in maintaining the effective operation of the SCR system is the proper management of AdBlue fluid. Agricultural machinery requires regular checking of the AdBlue level in the tank and its regular refilling to ensure continuous environmental protection and meet exhaust emission standards.

It is also worth remembering to store AdBlue in conditions that protect against contamination, avoid mixing it with other substances and follow the manufacturer’s recommendations regarding the maintenance and servicing of the SCR system. Thanks to these activities of adblue, agricultural machines will maintain high efficiency and compliance with applicable ecological standards.

What are the symptoms of AdBlue problems in agricultural machinery?

Problems with the AdBlue system in an agricultural machine may manifest themselves in many ways, depending on the type of fault and the machine model. Here are some typical signals that may indicate a problem with the AdBlue system:

1. AdBlue Warning Indicator: Many manufacturers equip their machines with dashboard indicators that alert you when the AdBlue fluid level is low or there are problems with the AdBlue delivery system.
2. ECU Fault Codes: Modern agricultural machinery often has advanced on-board diagnostic systems that can generate fault codes related to the SCR system. These error codes may need to be read by specialized diagnostic tools.
3. Reduced engine performance: If the AdBlue system is not functioning properly, it may lead to a reduction in engine power or an engine limp mode to prevent emissions from being exceeded.
4. Increased fuel consumption: A malfunctioning SCR system can cause the engine to become less efficient, resulting in higher fuel consumption.
5. Problems starting the machine: In extreme cases, if the AdBlue system is completely out of order, the agricultural machine may have problems starting or may not be able to work at all.
6. Sediment Accumulation: Improper operation of the AdBlue system can lead to contamination of the SCR catalytic converter, which may require cleaning or replacement.

If you experience any of these symptoms, we recommend that you contact us for further diagnosis and repair.

Disabling the SCR / DPF / EGR system adblue agricultural machines.

Although AdBlue is not essential for the proper operation of the engine, the controllers have been programmed so that without its presence the machine will not be able to operate.

A fault in the SCR system results in a reduction in machine power, necessitating repair. As with trucks, manufacturers must adapt to European emission standards.

The difference is that the prices of spare parts for construction and agricultural machines are three times higher than those intended for trucks – sometimes it is even the same NOx sensor that costs PLN 1,200 for a passenger vehicle and PLN 3,500 for a combine harvester.

We offer the option of disabling the SCR/DPF/EGR system, eliminating power limitations and removing errors displayed on the control panel of construction and agricultural machines.

What is DPF in an agricultural machine?

DPF, i.e. diesel particulate filter, is a device installed in the exhaust system of agricultural machines with diesel engines, which is used to eliminate soot particles and other solid pollutants emitted in the exhaust gases. This filter captures particulate matter and burns them periodically in a process called regeneration, which can be performed passively (during normal engine operation) or actively (by increasing the exhaust gas temperature).

What is the SCR system in an agricultural machine
and the impact of adblue on agricultural machinery?

The SCR (Selective Catalytic Reduction) system in an agricultural machine is an advanced exhaust emission control system used in modern diesel engines, which reduces nitrogen oxides (NOx) emissions into the atmosphere. The SCR system uses a solution called AdBlue, which is injected into the exhaust gas stream before a special catalytic converter.

In the SCR process, AdBlue, which is an aqueous solution of urea, decomposes in the exhaust gases into ammonia and carbon dioxide. The ammonia then reacts with the nitrogen oxides on the catalytic converter surface, converting them into nitrogen (N2) and water vapor (H2O), which are naturally occurring and safe components of air.

The SCR system is widely used in heavy agricultural equipment such as tractors, combines and other large vehicles because of its effectiveness in cleaning exhaust gases and enabling equipment manufacturers to meet strict emissions standards.

What is the EGR system and what impact does it have?
him adblue agricultural machinery?

The EGR (Exhaust Gas Recirculation) system in an agricultural machine is a mechanism that aims to reduce nitrogen oxides (NOx) emissions by recirculating part of the exhaust gases back to the combustion chamber. This process lowers the combustion temperature because recirculated exhaust gases contain less oxygen than fresh air, resulting in less production of NOx, which is mainly produced at high temperatures.

The EGR (Exhaust Gas Recirculation) system in an agricultural machine is a mechanism that aims to reduce nitrogen oxides (NOx) emissions by recirculating part of the exhaust gases back to the combustion chamber. This process lowers the combustion temperature because recirculated exhaust gases contain less oxygen than fresh air, resulting in less production of NOx, which is mainly produced at high temperatures.

The EGR system requires proper maintenance because the build-up of soot and other contaminants in the recirculating component can lead to reduced engine performance and operational problems. Cleaning and maintaining the EGR system is therefore an important aspect of keeping agricultural machinery in good technical condition.
