Where is the Exhaust Gas Recirculation (EGR) control system and what does this do?

A valve, usually situated near the intake manifold to recirculate some exhaust gases into the intake during vehicle cruise to reduce NOx emissions.|||It's a system that reintroduces uncombusted gas back in to your engine. It is usually found near where the air intake meets your engine.|||sends unburned gas back to the system to be burned causeing less emmisions. when it builds up the valve lets it back into the manifold or straight down to the cattalitic converter|||The EGR system came about to reduce NOx emissions to meet new EPA standards. It does this by introducing exhaust gases back into the combustion chamber to reduce combustion temperatures. The lower the temperature, the lower the NOx emissions. Simple as that.





Of course, when the EGR valve gets stuck open, the car has a tough time idling...





Good luck!|||It looks like a little flying saucer near your throttle body. And gases that didn't get burned up in the combustion chamber go through this to get sent back in to the Combustion chamber to get burned again.


Completely burned fuel emits less harmful things into the atmospere than gas that hasn't completely burned so the egr gives those gasses a chance to burn off completely.|||i own a repair shop,and the egr system takes unburned gas from the exhaust system,and runs it back through the intake manifold and then attempts to re-burn it it doesn't always work well,but on most cars it does help a lot,and the system does this all the time especially under acceleration,is when it mostly works,but that's pretty much what it does ,,good luck i hope this help,s.and have a good thanks giving.|||It depends on what kind of car that you have but generally it plumbs back into your intake tract somewhere. The function is to take unspent oxygen gases and route them back into the combustion chamber to be burned again.
