Hello!
Anyone tried out the cooled EGR system in practice on (gasoline engine)?
I modified my car yesterday to test it out: The cooled exhaust gas is taken from near the end of the exhaust pipe and runs through the installed pipe to the intake manifold.
Test car is 1990 passat with 2.0 doch engine.
Currently I do have no regulator valve for the egr. I just pinch the hose with clamp to get the desired flow. I have adjusted so that the car is still able to idle, opened up the idle screw fully. Bad that this engine have mechanical injection, so there is no easy way to measure the fuel consumpion(mpguino). I will take longer trip some day soon and lets see if I notice some fuel saving.
