EGR question(s)
next question: in 01/02 egr was eliminated in the ls1, right? then how the heck do they pass emissions testings?
also, is egr still commonly used in cars? i figured since chevy stopped doing it in the ls1 a lot of other manufacturers found an alternative.
and lastly, is egr actually better for the environment? seems like egr is only delaying the amount of exhaust that comes out of your car since you are recycling it but that either way, with or without egr, the exhaust still comes out of the car, just the concentration is limited by the egr system.
thanks for the answers.
the EGR valve only operates under crusing conditions. it is an emissions device and it will effect a sniffer check. a good idea is to have your A/F richened up a tad when you remove the EGR to keep the combustion chamber temps down.
