10 Common Symptoms Of Bad EGR valve

#egr_valve #egrsystem #exhaust
The primary function of the EGR valve is to reduce nitrogen oxide emissions by recirculating a portion of exhaust gases back into the engine's combustion chambers. By reintroducing these exhaust gases into the combustion chamber, the overall oxygen concentration is reduced, lowering the peak combustion temperatures. High temperatures can lead to the formation of nitrogen oxide.
In this video, we discuss the symptoms of a faulty EGR valve. When the EGR valve goes bad, it produces different signs such as rough idle, poor fuel economy, performance issues, check engine light illumination, excessive exhaust emissions, engine knocking, carbon buildup, engine misfires, or increased engine temperature.
