You do realize what an EGR system does, and why, right? They are currently used in every production gasoline engine. .............................But what do I know.
It shows you don't know that EGR systems are NOT used in "every" production made. I have a 2004 Ford Ranger without an EGR system. There are many new vehicles made without them. I've worked on dealership lines since 1980 so I think I know about EGR systems. I've done diagnosis and repair on turbos while on the line and sat through some turbo repair and theory classes for Ford, GM and Chrysler, so I know a touch about how turbos work. I'm no expert....and I've said it many times. Me personally, I don't like turbos. I don't really give a rat's butt how you think they work, either. I think sometimes you'd argue about how to take a piss just for arguement's sake.
