Since the 1960s, vehicle manufacturers have installed Exhaust Gas Recirculation (EGR) valves to reduce nitrous oxide (NOX) emissions. The EGR valve recirculates a small amount of exhaust into the combustion cycle. The warmth of the exhaust lets the combustion chambers warm up quickly, while the spent, inert gases keep the chambers from getting too hot when the engine fully warms up. Whether mechanical or electronic, EGR valves open and close to control the gas flow. If left open, the excess vacuum will cause the engine to act like it wants to stall, idling roughly or surging. If the valve stays closed, detonation could occur in the combustion chambers; this knocking or pinging will lower mileage and the lifespan of the engine. To smooth a rough idle or hesitant or surging acceleration, and reduce knocking, clean your EGR valve.
In diesel engines, fouling as a result of soot accumulation and depositing occurs as a result of driving at low revs, eco driving or from making short journeys. If fouling occurs anywhere in the diesel engine, the dirt quickly spreads through the entire intake system, as a result of which the engine starts to run irregularly and eventually it even cuts out. This dirt does not go away of its own accord or from regular motorway driving. The intake system must therefore be pointedly and preventively cleaned.
