EGR Valve Solution
The EGR valve is an electropneumatic valve. It is located in the engine compartment and is used to control the exhaust gas recirculation process. The EGR system ensures that the fresh air entering the engine mixes with a low amount of burned exhaust gas, reducing the combustion temperature and the amount of excess oxygen in the engine's combustion chamber.
EGR has undertaken the task of reducing NOx emissions by lowering the high combustion temperatures where nitrogen oxides are formed. In modern engines, EGR is designed both to reduce the engine's suction power and to use the positive effect of waste gas on combustion in certain driving situations.
What are EGR valve malfunctions?
EGR valve can soot over time due to exhaust gases. Accordingly, the need for cleaning the EGR valve arises. The accumulation of soot, similar to coal dust, can cause this part to malfunction and deteriorate over time. Therefore, EGR valve cleaning and maintenance should be done at the right time and should be changed when necessary.
