What Is Adblue?
In vehicles with Euro 4, Euro 5, Euro 6 engines, the exhaust gases are transferred to the SCR catalyst with an injector before they reach the Adblue catalyst. The high heat generated in the exhaust turns Adblue into gas.
Then the substance and gas react with each other and turn into non-harmful water vapor. Adblue cannot be controlled at the services, so vehicles often encounter AdBlue malfunctions.
What Is Dpf And Egr Solutions?
DPF and EGR; They are the engine parts that determine the “Exhaust Emission Standards” of the vehicles (such as Euro 4 – Euro 5 – Euro 6) and work in association with the exhaust systems of the vehicles so that the exhaust gases pollute the air less.
DPF “Diesel Particulate Filter” is used to minimize harmful soot particles in the exhaust gases with high heat.
What Is Egr Valve? (Exhaust Gas Recirculation)
The EGR Valve, on the other hand, allows some of the exhaust gases to be thrown back into the engine, so that the combustion reaction rate in the combustion chamber decreases and the combustion temperature decreases.
The low combustion temperature ensures the reduction of nitrogen oxide emissions.
The EGR Valve is deactivated by the control unit when the engine is running at full load, because good power gain requires an excess of oxygen in the combustion chamber.
Mercedes Sprinter is one of the commercial vehicles actively used today. This vehicle has a Diesel Particulate Filter (DPF) and Exhaust Recycle Valve (EGR) and Adblue system.
How To Solve Dpf And Egr?
EGR, DPF, SCR systems that can be resolved with software are solved by reading the ECU of the vehicle, modifying the software and writing it back to the ECU of the vehicle. First of all, you need an Ecu Programming Device.
In the software, we define the system that we want to fix. For example, the vehicle’s EGR system is faulty.
After the necessary regulation are done in the software, the modified file is rewritten to the vehicle’s ECU.
The modified ecu sends updated signals and fix the malfunctions in the vehicle. This is the most preferred solution method with both cost and time savings.
Repairing the system from scratch or finding and repairing defective parts are very laborious, expensive and time-consuming solutions.
If you want, you can buy an ecu programming device and you can overcome these malfunctions yourself, or you can get service from Nitro Mechatronics Garages located all over Turkey.
