What does the EGR system actually do on a diesel engine? In modern inline-six engines used in semi trucks, exhaust gases don’t just leave the engine — a portion is routed back into the intake through the EGR system.As exhaust gases drive the turbo and fresh air is cooled and fed into the intake, the EGR valve diverts a controlled amount of exhaust through a cooler and reintroduces it into the intake stream. This process is called Exhaust Gas Recirculation (EGR).EGR isn’t designed for performance

Common EGR System Problems- EGR Valve Failure: A faulty EGGR valve can lead to poor engine performance, rough idling, and increased emissions. It may become stuck open or closed, disrupting the proper flow of exhaust gases.- Clogged EGR Cooler: Over time, carbon deposits and soot can build up in the EGGR cooler, restricting the flow of exhaust gases. This can cause overheating, decreased EGR efficiency, and potential engine damage.- EGR Sensor Failure: The EGR system relies on sensors to monitor
