[Vwdiesel] intercoolers

[Kenneth E. Oldrid]

Hey Fred,
it seems to me that intercoolers are a type of air to air heat exchanger,
cooling the intake air after it's compressed by the turbo.
When the turbo compresses the intake air, it heats it as well. This is because
the turbo is powered by and connected to the exhaust gasses and manifold. The
heated air expands, becoming less dense, which has less O2. We want more O2 per
unit area in our intake air to facilitate complete combustion of the fuel
(ecodiesels). More O2 also allows more fuel to be injected and thus combusted,
yielding more power(normal TD).
So, the hot compressed air is passed through the intercooler. The air cools,
becoming more dense. The end product is compressed air with more O2 and more
power.
I believe the TDI's are the only VW diesels to come stock with intercoolers, in
the US anyway. Is this true?
