go to google and search:
"clean_and_cool.pdf"

it should be the first link.

Regards.

I was thinking about the heat exchangers which cool down EGR gasses with coolant (like in most new turbodiesels): We ecomodders want to run our engines hotter than normal, but then the coolant is also hotter, so there is less EGR cooling. So in a gasser, why not use intake air for cooling? It is almost always colder than coolant, it works like a WAI, and if the HX gets a leak, then there is not too much wrong with some exhaust gasses seeping into the intake.

You don't want to cool the EGR gas down too much so that it condenses. If it does you now have to worry about water in the EGR system.

I think that water is not a problem, but different impurities that accumulate to cooler with moisture and eventually block it.

There you go:

Maybe a "water bubbling filter" like the guys that run the wood gasifyers have should prevent that...

I'd like to dabble with EGR mods first beginning with EGR cooling. For the sake that i have an archaic 80 car and no cooler. Rather than complicate my cooling system i'd rather have an air cooled heat exchanger by means of tapping the exhaust pipe further down stream.

Should get my egr source at a medium temp in front of the cat or after the cat at the coldest point. I plan to return it to the engine with 5 - 10 feet of copper tubing. I understand it should not be cooled too much.

My main question is should I take advantage of unburned combustibles before the cat or go for max cooling and keep the intake charge dense???

Thanks!
