Mercedes Truck EGR Exhaust Gas Recirculators (all models up to MP4)

As in other trucks, also in Mercedes vehicles, EGR exhaust gas recirculation devices are used, the function of which is to reduce harmful substances that are emitted into the atmosphere. We have already introduced information about the recirculators themselves quite thoroughly on our company’s offer pages, as well as in other entries on our blog, so in this post we will only focus on general information about this system, as well as on the Mercedes trucks themselves.

Operation and functions of Mercedes EGR recirculators

The function of the EGR exhaust gas cooler in Mercedes trucks is to reduce the content of harmful substances in the exhaust gases. These are carbon monoxide (CO), nitrogen oxides (NOx) and hydrocarbons (CH).

• Operation: An appropriate amount of exhaust gas is introduced into the combustion chamber, the presence of which in the combustion chamber causes chemical reactions, thanks to which less harmful substances are formed.
• Faults: The recirculators fail mainly from a build-up of debris that overloads the EGR valve controls. They can also be caused by the fact that the materials are burned off by the exhaust fumes.
• Care: Mercedes EGR valve failures can be prevented by using clean fuel and by regularly servicing the vehicle and cleaning the engine from deposits.
• Symptoms of damage: Drop in engine power, uneven operation and difficult start, limited flow of exhaust gases to the intake system or lack of smoothness during acceleration.
